The Sony PlayStation DualSense, DualShock 4, Nintendo Switch JoyCons (used in pairs), and Nintendo Switch Pro Controller have much in common. They have many of the features expected of modern game controllers. They also have an incredibly versatile and underutilised input that their biggest rival (Microsoft's Xbox One controller) doesn't have: a 3-axis gyroscope (from here on, “gyro”).
My goal with JoyShockMapper is to enable you to play PC games with DS, DS4, JoyCons, and Pro Controllers even better than you can on their respective consoles -- and demonstrate that more games should use these features in these ways.

For developers, version 2.2 and older serve as a reference implementation for using JoyShockLibrary to read inputs from DualShock 4, DualSense, JoyCons, and Pro Controller in your games. It now uses SDL2 for controller support, and I've made code contributions to SDL2 to make sure it covers the same features.
JoyShockMapper is also a reference implementation for many of the best practices described on GyroWiki.
JoyShockMapper is primarily developed on Windows. JoyShockMapper should now be able to be built on and for Linux. See the instructions for that below. Please let us know if you have any trouble with this.

JoyShockMapper is written in C++ and is built using CMake.
The project is structured into a set of platform-agnostic headers, while platform-specific source files can be found in their respective subdirectories. The following files are platform-agnostic:
include/JoyShockMapper.h- This header provides important type definitions that can be shared across the whole project. No variables are defined here, only constants.include/InputHelpers.h- This is platform agnostic declaration of wrappers for OS function calls and features.include/PlatformDefinitions.h- This is a set of declarations that create a common ground when dealing with platform-specific types and definitions.include/TrayIcon.h- This is a self contained module used to display in Windows an icon in the system tray with a contextual menu.include/Whitelister.h- This is another self contained Windows specific module that uses a socket to communicate with HIDCerberus and whitelist JSM, the Linux implementation, currently, is a stub.include/CmdRegistry.h- This header defines the base command type and the CmdRegistry class that processes them.include/JSMAssignment.hpp- Header for the templated class assignment commandsinclude/JSMVariable.hpp- Header for the templated core variable class and a few derivatives.src/main.cpp- This does just about all the main logic of the application. The core processing logic should be kept in the other files as much as possible, and have the JSM specific logic in this file.src/CmdRegistry.cpp- Implementation for the command line processing entry point.src/operators.cpp- Implementation of all streaming and comparison operators for custom types declared inJoyShockMapper.h
The Windows implementation can be found in the following files:

Generate the project by runnning the following in a command prompt at the project root:
- Windows:
mkdir build && cd build- To create a Visual Studio x86 configuration:
cmake .. -G "Visual Studio 16 2019" -A Win32 . - To create a Visual Studio x64 configuration:
cmake .. -G "Visual Studio 16 2019" -A x64 .
- Linux:
mkdir build && cd buildcmake .. -DCMAKE_CXX_COMPILER=clang++ && cmake --build .
Please note that JoyShockMapper is primarily written for Windows and is a program in rapid development.
While JSM can be built for Linux, please note that the rapid pace of development and limited number of Linux maintainers means that the Linux release may not always build.
In order to build on Linux, the following dependencies must be met, with their respective development packages:
- clang++ (see below bug)
- gtk+3
- libappindicator3
- libevdev
- libusb
- SDL2
- hidapi
Distribution-Specific Package Names:
- Fedora:
clang SDL2-devel libappindicator-gtk3-devel libevdev-devel gtk3-devel libusb-devel hidapi-devel - Arch:
clang sdl2 libappindicator-gtk3 libevdev gtk3 libusb hidapi - Please provide an issue report or pull request to have additional library lists added.
Due to a bug in GCC, the project in its current form will only build with Clang.
JoyShockMapper was initially developed for Windows, this has the side-effect of some types used through the code-base are Windows specific. These have been redefined on Linux. This was done to keep changes to the core logic of the application to a minimum, and lower the chance of causing regressions for existing users.
The application requires rw access to /dev/uinput, and /dev/hidraw[0-n] (the actual device depends on the node allocated by the OS). This can be achieved by chown-ing the required device nodes to the user running the application, or by applying the udev rules found in dist/linux/50-joyshockmapper.rules, adding your user to the input group, and restarting the computer for the changes to take effect. More info on udev rules can be found at https://wiki.archlinux.org/index.php/Udev#About_udev_rules.
The application will work on both X11 and Wayland, though focused window detection only works on X11.
The latest version of JoyShockMapper can always be found here. All you have to do is run JoyShockMapper.exe.
Included is a folder called GyroConfigs. This includes templates for creating new configurations for 2D and 3D games, and configuration files that include the settings used for simple Real World Calibration.
-
Connect your controller either with a usb cable or via bluetooth. Most modern controllers will be suported, including all Xbox, Playstation and Switch controllers, although Xbox and many others don't have the gyro sensor required for gyro controls.
-
Run the JoyShockMapper executable, and you should see a console window welcoming you to JoyShockMapper.
- In the console you can start entering bindings : [button name] = [key name]. See Digital Inputs section for details on how buttons and keys are named.
- Sticks, the gyro and analog triggers require some more configuration: typically some MODE you want to set, a sensitivity value and some other settings. Each is explained in the corresponding section. They follow the same format : [setting name] = [value]
- Buttons and settings will display their current values if you only enter their name in the console.
- Settings can display a short description of what they do if you enter [setting name] HELP
- There are quite a few commands that do not work as assignments like above but just runs a function. For example RECONNECT_CONTROLLERS will update the controller listing, and RESET_MAPPINGS will set all settings and bindings to default. README will lead you to this document!
- You will find a JoyShockMapper icon in the system tray: right click on it to display a quick list of commands and configuration files.
-
JoyShockMapper can load all the commands contained in a text file.
- Enter the file's path and name in the console. If the file path is too long, or contains unusual characters, enter the relative path instead (eg: GyroConfigs/config.txt).
- Every line of the text file will be run as a command typed directly into the console. The pound # symbol starts a comment until the end of the line and will be ignored by JoyShockMapper.
- You can find example configuration files in the GyroConfigs folder. Files can refer one another : feel free to edit those in GyroConfigs as your customized gyro configuration for example.
- Find more details in the Configuration Files section.
-
If you're using a configuration that utilises gyro controls, the gyro will need to be calibrated (to be told what "not moving" is). See Gyro Mouse Inputs section for more info on that, but here's the short version:
- Put all controllers down on a still surface;
- Enter the command RESTART_GYRO_CALIBRATION to begin calibrating them;
- After just a couple of seconds, enter the command FINISH_GYRO_CALIBRATION to finish calibrating them.
- These commands are also accessible via the tray icon contextual menu as well.
- JoyShockMapper relies on a Real World Calibration value for some features such as flick stick. If you didn't find this value in the online database, check the Real World Calibration section to calculate it yourself.
-
If you run into some issues, make sure you check the Troubleshooting section and Known and Perceived Issues. If you couldn't find your answer, you can find more help online on the GyroGaming subreddit and its affiliated Discord Server.
Commands can be executed by simply typing them into the JoyShockMapper console windows and hitting 'enter'. You can see the list of all available commands by entering HELP, or all commands containing STICK by typing HELP STICK for example. Since there's a quite a lot of them, they are organized in this document by what part of the controller or software they affect.
Commands can mostly be split into 8 categories:
- Digital Inputs. These are the simplest. Map a button press or stick movement to a key or mouse button. There are many binding options available, such as tap & hold, simultaneous press, chorded press and more.
- Analog Triggers. Many controllers have 2 analog triggers: L2 and R2 on Playstation for example. JoyShockMapper can set different bindings on both "soft pull" and "full pull" of the trigger, maximizing use of those triggers. This feature is unavailable to controllers that have digital triggers, like the Nintendo Pro and Joycons.
- Stick Configuration. Joysticks can drive the mouse or trigger key presses in many different ways, such as flick stick or scroll wheel. They need to be set a mode, and some settings particular to that mode. This is all explained in this section.
- Gyro Mouse Inputs. Controlling the mouse with gyro generally provides far more precision than controlling it with a stick. Think of a gyro as a mouse on an invisible, frictionless mousepad. The mousepad extends however far you're comfortable rotating the controller. For games where you control the camera directly, stick mouse inputs provide convenient ways to complete big turns with little precision, while gyro mouse inputs allow you to make more precise, quick movements within a relatively limited range.
- Real World Calibration. This calibration value makes it possible for flick stick to work correctly, for the gyro and aim stick settings to have meaningful real-life values, and for players to share the same settings between different games.
- ViGEm Virtual Controller. JoyShockMapper can connect to Nefarius' ViGEm bus software to create virtual xbox controllers and virtual DS4 controllers. To make use of this feature you need to download and install the latest release at this link.
- Modeshifts. The controller configuration can dynamically change depending on the current button presses, in a way akin to chorded presses. This is handy to handle weapon wheels for example. These are called modeshifts to echo the Steam Input naming convention.
- Miscellaneous Commands. These don't fit in the above categories, but are nevertheless useful. They typically are related to JoyShockMapper itself rather than the controller configuration.
So let's dig into the available commands.
Digital inputs are really simple. They are structured mostly like the following:
[Controller Input] = [Key or Mouse Button]
For example, to map directional pad LEFT to the F1 key, you'd enter:
LEFT = F1
One important feature of JoyShockMapper is that a configuration that works for a PlayStation controller works the same for a pair of JoyCons or a Pro Controller. Because JoyCons can have slightly more inputs than the DualShock 4, the button names are mostly from the Nintendo devices. The main exceptions are the face buttons and the stick-clicks. Because they are named more concisely, the stick-clicks are named after the DualShock 4: L3 and R3.
The face buttons are a more complicated matter.
The Xbox layout has become the defacto layout for PC controllers. Most PC gamers who use some sort of controller will be familiar with the Xbox layout, whether from Xbox controllers, Steam controller, or other 3rd party controllers that can be interpreted by a game as an Xbox controller. Even PlayStation users will be somewhat used to interpreting Xbox face button names. Nintendo devices have the same face buttons in a different layout. X and Y are swapped, and so are A and B. Nintendo's layout has also been around for longer, but is less familiar to PC players.
So the best solution, in my opinion, is to use neither layout, and use an unambiguous layout with button names that aren't used by any controller, but still have obvious positions: the cardinal layout. North, East, South, West, denoted by N, E, S, W, respectively.
So, here's the complete list of digital inputs:
UP, DOWN, LEFT, RIGHT: D-pad directional buttons
L: L1, LB or L the top left shoulder button
ZL: L2, LT or ZL the bottom left shoulder button (or trigger)
R: R1, RB or R, the top right shoulder button
ZR: R2, RT or ZR, the bottom right shoulder button
ZRF: Full pull binding of right trigger, only on controllers with analog triggers
ZLF: Full pull binding of left trigger, only on controllers with analog triggers

E: The East face button, â—‹, B (Xbox) or A (Nintendo)
S: The South face button, ⨉, A (Xbox) or B (Nintendo)
W: The West face button, â–ˇ, X (Xbox) or Y (Nintendo)
LUP, LDOWN, LLEFT, LRIGHT: Left stick tilted up, down left or right

GYRO_TRACKBALL, GYRO_TRACK_X, GYRO_TRACK_Y: Keep last gyro input, or in just the x or y axes, respectively
; ' , . / \ [ ] + - `
"any console command": Any console command can be run on button press, including loading a file
SMALL_RUMBLE, BIG_RUMBLE, Rhhhh: rumble commands. The 'h' are capital hex digits, such as 'R8000' or 'RFFFF'
For example, in a game where R is 'reload' and E is 'use’, you can do the following to map □ to 'reload' and △ to 'use':
W = R
N = E
Those familiar with Steam Input can implement Action Layers and Action Sets using the quotation marks to load a file on demand. That file can contain partial or full remapping of the controller bindings. This is very useful for having a different scheme for vehicles, menus or characters.
# Load the driving control scheme.
HOME = "Autoload/GTA5/GTA_driving.txt" # That file should bind HOME to loading the walking scheme file!
Take note that the command bound in this way cannot contain quotation marks, and thus cannot contain the binding of a command itself. In this case, you should put the command in a file and load that file.
Since a keyboard has many more inputs available than most controllers, console games will often map multiple actions to the same button while the PC version has those actions mapped to different keys. In order to fit keyboard mappings onto a controller, JoyShockMapper allows you to map taps and holds of a button to different keyboard/mouse inputs. So let's take that same game and make it so we can tap â–ˇ to 'reload' or hold â–ˇ to 'use':
W = R E
If you want â–ˇ to 'reload' when tapped, but do nothing at all when held, you can do the following:
W = R NONE
The time to hold the button before enabling the hold binding can be changed by assigning a number of milliseconds to HOLD_PRESS_TIME. The default value is 150 milliseconds.
See the tap press and hold press event modifiers below for more details on how keybinds are applied.
Taps and holds are the most common bindings used on a controller. But sometimes, you will find the need to require bindings that are somewhat more complicated, either because you want to work around an in-game behaviour, or you want to create some unusual key press combination. In any case, JoyShockMapper allows you to highly customize how mappings are assigned to your button through binding modifiers.
Before we dive in, there's a few notions to understand. A key press always involves a key down and a key up action. In a simple binding, JoyShockMapper will match the button down and button up events with a key down and key up action respectively. However when you use Tap and Hold bindings, JoyShockMapper will bind the key down and key up to different events that will happen a certain time while the button is down and after the button is released. Some bindings do not have a matching "key up" action such as scroll wheel bindings and console command bindings.
There are two kinds of modifiers that can be applied to key bindings: action modifiers and event modifiers. They are represented by symbols added before and after the key name respectively. And each binding can only ever have one of each. You can however have multiple keys bound to the same events, thus sending multiple key presses at once.
Action modifiers affect how the key down and key up actions are bound to the events. They come in two kinds: toggle (^) and instant (!).
- ^ Toggle makes it so that the key will alternate between applying and releasing the key at each press.
- ! Instant will send the key up action very shortly after the key down, making it seem instant.
Event Modifiers affect what button events the key up and key down actions will be bound to. They come in five kinds: start press (\), release press (/), tap press ('), hold press (_),\ and turbo (+).
- \ Start press is the default event modifier when there is only a single key bind. It will apply the key down action as soon as the button is pressed and the key up when the button is released by default. This can be useful to have a key held while other keys are being activated.
- / Release press will apply the binding when the button is released. A binding on release press needs an action modifier to be valid.
- ' Tap press is the default event modifier for the first key bind when there are multiple of them. It will apply the key press when the button is released if the total press time is less than the
HOLD_PRESS_TIME. By default the key press is released a short time after, with that time being longer for gyro related actions and calibration. - _ Hold press is the default event modifier for the second key bind when there are multiple of them. It will apply the key only after the button is held down for the
HOLD_PRESS_TIME. By default, the key is released when the button is released as well. - + Turbo will apply a key press repeatedly (with consideration of action modifiers), resulting in a fast pulsing of the key. The turbo pulsing starts only after the button has been held for
HOLD_PRESS_TIME.
These modifiers can enable you to work around in game tap and holds, or convert one form of press into another. Here's a few example of how you can make use of those modifiers.
ZL = ^RMOUSE\ RMOUSE_ # ADS toggle on tap and release the toggle on hold
E = !C\ !C/ # Convert in game toggle crouch to regular press
UP = !1\ 1 # Convert Batarang throw double press to hold press
W = R E\ # In Halo MCC, reload on tap but apply E right away to cover for in-game hold processing
-,S = SPACE+ # Turbo press for button mash QTEs. No one likes to button mash :(
R3 = !1\ LMOUSE+ !Q/ # Half life melee button
UP,UP = !ENTER\ LSHIFT\ !G\ !L\ !SPACE\ !H\ !F\ !ENTER/ # Pre recorded message
UP,E = BACKSPACE+ # Erase pre recorded message if I change my mind
Take note that the Simultaneous Press below introduce delays in the raising of the events (notably StartPress) until the right mapping is determined. Those time windows are not added but events will be pushed together within a poll callback or two.
Also, Double Press bindings has some special timing handling in order to give the user the option to have the first binding skippable or not. See its dedicated section below for details
Finally, Here is a graph containing a comprehensive description of when the button events are raised over the course of a press.
less than 150 ms hold time
150 ms hold time 80ms turbo period V 500 ms for gyro and calibration
V V |------|< actions or 40 ms otherwise
______|-----|---|---|---|---|---|--|___________|---|____________

(a) (b) (c) (c) (c) (c) (c)(d) (a) (d) (g)
(c) (f) (e)

c: turbo +
d: release press /

Events a, b, c, d and e have an Instant Release event attached to them 40ms after they occur.
JoyShockMapper additionally allows you to map simultaneous button presses to different mappings. For example you can bind character abilities on your bumpers and an ultimate ability on both like this:
L = LSHIFT # Ability 1
R = E # Ability 2
L+R = Q # Ultimate Ability
To enable a simultaneous binding, both buttons need to be pressed within a very short time of each other. Doing so will ignore the individual button bindings and apply the specified binding until either of the button is released. Simultaneous bindings also support tap & hold bindings as well as modifiers just like other mappings. This feature is great to make use of the dpad diagonals, or to add JSM specific features like gyro calibration and gyro control without taking away accessible buttons.
The time window in which both buttons need to be pressed can be changed by assigning a different number of milliseconds to SIM_PRESS_WINDOW. This setting cannot be changed by modeshift (covered later).
Chorded press works differently from Simultaneous Press, despite being similar at first blush. A chorded press mapping allows you to override a button mapping when the chord button is down. This enables a world of different practical combinations, allowing you to have contextual bindings. Here's an example for Left 4 Dead 2, that would enable you to equip items without lifting the thumb from the left stick.
W = R E # Reload / Use
S = SPACE # Jump
E = CONTROL # Crouch
N = T # Voice Chat
L = Q NONE # Other weapon, hold to select with face button.
L,W = 3 # Explosives
L,S = 4 # Pills
L,E = 5 # Medpack
L,N = F # Flashlight
A button can be chorded with multiple other buttons. In this case, the latest chord takes precedence over previous chords. This can be understood as a stack of layers being put on top of the binding each time a chord is pressed, where only the top one is active. Notice that you don't need to have NONE as a binding : the chord binding could very well be bound to a button that brings up a weapon wheel for example.
You can also assign the double press of a button to a different binding. Double press notation is the same as chorded button notation, except the button is chorded with itself. It supports taps & holds and modifiers like all previous entries.
The double press binding is applied when a down press occurs within 150 milliseconds from a previous down press. The regular binding will apply any on press event on the first press, but will only apply the tap binding if the second press is ommitted and with a delay. The double press binding also supports tap & hold bindings as well as modifiers. The time window in which to perform the double press can be changed by assigning a different number of milliseconds to DBL_PRESS_WINDOW.
N = SCROLLDOWN # Cycle weapon
N,N = X # Cycle weapon fire mode
W = !E\ # Pick up item
W,W = I # Pick up item and open Inventory
E = C' # Crouch
E,E = Z # Don't crouch but go prone
Lastly, there is one digital input that works differently, because it can overlap with any other input. Well, two inputs, but you'll use at most one of them in a given configuration:
GYRO_OFF
GYRO_ON
When you assign a button to GYRO_ON, gyro mouse only work while that button is pressed. GYRO_OFF disables the gyro while the button is pressed. This is a really important feature absent from most games that have gyro aiming -- just as a PC gamer can temporarily "disable" the mouse by lifting it off the mousepad in order to reposition it, a gyro gamer should be able to temporarily disable the gyro in order to reposition it. This binding doesn't affect other mappings associated with that button. This is so that the gyro can be enabled alongside certain in-game actions, or so that the gyro can be disabled or enabled instantly regardless of what taps or holds are mapped to that button.
For games that really need to use all the buttons available on the controller, but one of those inputs is rarely used and can be toggled easily (like crouching, for example), it might make sense to make that input tap-only, and make it double as the gyro-off button when held:
E = LCONTROL NONE
GYRO_OFF = E
Or if you really can't spare a button for disabling the gyro, you can use LEFT_STICK or RIGHT_STICK to disable the gyro while that input is being used:
GYRO_OFF = RIGHT_STICK # Disable gyro while aiming with stick
I prefer to be able to use stick aiming (or flick stick) at the same time as aiming with the gyro, but this can still be better than having no way to disable the gyro at all if your game doesn't have an obvious function to tie to enabling gyro aiming (like a dedicated "aim weapon" button as is common in third-person action games).
GYRO_ON is really useful for games where you only sometimes need to aim precisely. If ZL causes your character to aim their bow (like in Zelda: Breath of the Wild or Shadow of Mordor), maybe that's the only time you want to have gyro aiming enabled:
ZL = RMOUSE # Aim with Bow
GYRO_ON = ZL # Turn on gyro when ZL is pressed
GYRO_ON and GYRO_OFF can also be bound as an action to particular buttons. Contrary to the command above, this takes the spot of the action binding. But you can still find creative ways with taps & holds or chorded press to bind the right gyro control where you need it.
Take note that taps apply gyro-related bindings for half a second. Another option is inverting the gyro input with GYRO_INVERT. Such a binding can be handy if you play with a single joycon because you don't have a second stick. When that action is enabled, the inversion makes it so that you can recenter the hands by continuing to turn in the opposite direction!
SL + SR = GYRO_OFF GYRO_INVERT # Disable for .5s / Invert axis on simultaneous bumper hold
Bound gyro actions like those have priority over the assigned gyro button should they conflict.
The command NO_GYRO_BUTTON can be used to remove the gyro-on or gyro-off mapping, making gyro always enabled. To have it always disabled, just set GYRO_ON = NONE or leave GYRO_SENS at 0.
If you're using GYRO_TRACKBALL or its single-axis variants, you can use TRACKBALL_DECAY to choose how quickly the trackball effect loses momentum. It can be set to 0 for no decay. Its default value of 1 halves the gyro trackball's momentum over each second. 2 will halve it in 1/2 seconds, 3 in 1/3 seconds, and so on. Some smoothing is applied when getting the trackball initial velocity in order to reduce the effects of noise or controller instability when pressing the button.
The following section does not apply to Joycons and Switch Pro controllers because they only have digital triggers.
Analog triggers report a value between 0% and 100% representing how far you are pulling the trigger. Binding a digital button to an analog trigger is done using a threashold value. The button press is sent when the trigger value crosses the threashold value, sitting between 0% and 100%. The default threashold value is 0, meaning the slightest press of the trigger sends the button press. This is great for responsiveness, but could result in accidental presses. The threashold can be customized by running the following command:
TRIGGER_THRESHOLD = 0.5 #Send Trigger values at half press
The same threashold value is used for both triggers. A value of 1.0 or higher makes the binding impossible to reach.
Hair trigger is also implemented: to enable it, assign a value of -1 as the trigger threshold. When hair trigger is used, the binding is enabled when the trigger is being pressed and held, and released when the trigger is being released. This allows quick tap shooting by pulsing the trigger.
JoyShockMapper can assign different bindings to the full pull of the trigger, allowing you to double the number of bindings put on the triggers. The way the trigger handles these bindings is set with the variables ZR_MODE and ZL_MODE, for R2 and L2 triggers. Once set, you can assign keys to ZRF and ZLF to make use of the R2 and L2 full pull bindings respectively. In this context, ZL and ZR are called the soft pull binding because they activate before the full pull binding does at 100%. Here is the list of all possible trigger modes.
NO_FULL (default): Ignore full pull binding. This mode is enforced on controllers who have digital triggers.
NO_SKIP: Never skip the soft pull binding. Full pull binding activates anytime the trigger is fully pressed.
NO_SKIP_EXCLUSIVE: Never skip the soft pull binding. When Full pull binding is active, the soft pull binding isn't.
MUST_SKIP: Only send full pull binding on a quick full press of the trigger, ignoring soft pull binding.
MAY_SKIP: Combines NO_SKIP and MUST_SKIP: Soft binding may be skipped on a quick full press, and full pull can be activated on top of soft pull binding.
MUST_SKIP_R: Responsive version of MUST_SKIP. See below.
MAY_SKIP_R: Responsive version of MAY_SKIP. See below.
For example, in Call of Duty you have a binding to hold your breath when aiming with a sniper. You can bind ADS on a soft trigger press and hold breath on the full press like this:
ZL_MODE = NO_SKIP # Enable full pull binding, never skip ADS
ZL = RMOUSE # Aim Down Sights
ZLF = LSHIFT # Hold breath
Using NO_SKIP mode makes it so that LSHIFT is only active if RMOUSE is active as well. Then on the right trigger, you can bind your different attack bindings: use the skipping functionality to avoid having them conflict with eachother like this:
TRIGGER_THRESHOLD = -1 # Use hair trigger for primary fire
ZR_MODE = MUST_SKIP # Enable full pull binding, soft and full bindings are mutually exclusive
ZR = LMOUSE # Primary Fire
ZRF = V G # Quick full tap to melee; Quick hold full press to unpin grenade and throw on release
Using MUST_SKIP mode makes sure that once you start firing, reaching the full pull will not make you stop firing to melee.
The "Responsive" variants of the skip modes enable a different behaviour that can give you a better experience than the original versions in specific circumstances. A typical example is when the soft binding is a mode-like binding like ADS or crouch, and there is no hold or simultaneous press binding on that soft press. The difference is that the soft binding is actived as soon as the trigger crosses the threshold, giving the desired responsive feeling, but gets removed if the full press is reached quickly, thus still allowing you to hip fire for example. This will result in a hopefully negligeable scope glitch but grants a snappier ADS activation.
The Dualsense controller features adaptive trigger that allow software to control the force feedback applies on the triggers. JoyShockMapper makes use of this feature to provide useful feedback depending on the trigger mode and position of the trigger. If you don't want JSM to use this feature, it can be disbaled across the board with the following command:
ADAPTIVE_TRIGGER = OFF # Don't use force feedback in my triggers
While adaptive triggers are enabled, the Dualsense controller will ignore hair trigger threshold, and consider it to be simply threshold zero. This is because the adaptive triggers fulfill the purpose of hair triggers by restricting uneccessary travelling distance. With adaptive triggers turned off, regular hair trigger is then accessible.
Each trigger and each devices might have slightly different trigger properties, which causes a mismatch between the reported trigger position and the position setting in the resistance packet. Each trigger thus gets 2 new settings, an offset and a range, that can be determined through a single-time calibration procedure. You can start this procedure by entering the command CALIBRATE_TRIGGERS : you will be required to gently press on a trigger just until you feel the resistance push back. Then you press a button and you will feel the trigger slowly lower : make sure you press gently. Once you reach full press JSM will display to you the calculated offset and range for your trigger. The same procedure is done on the other trigger after.
You should set these values in your OnReset.txt file so that they are always set properly for your controller.
LEFT_TRIGGER_OFFSET = 20 # My DS trigger calibration values
LEFT_TRIGGER_RANGE = 167
RIGHT_TRIGGER_OFFSET = 31
RIGHT_TRIGGER_RANGE = 175
User Nielk1 has reverse engineered the adaptive trigger data and developped a C# utility for it. With his permission (and under MIT licence) I've C++-ified the code and integrated it into JSM. Two new settings are then available LEFT_TRIGGER_EFFECT and RIGHT_TRIGGER_EFFECT. They can be set to OFF or ON (JSM handling) or be provided with one of Nielk1's functions.
RESISTANCE start[0 9] force[0 8]: Some resistance starting at point
BOW start[0 8] end[0 8] forceStart[0 8] forceEnd[0 8]: increasingly strong resistance

Each stick has 8 different operation modes when you're not using a virtual controller:
AIM: traditional stick aiming
FLICK: flick stick
FLICK_ONLY: flick stick without rotation after tilting the stick
ROTATE_ONLY: flick stick rotation without the initial flick
MOUSE_RING: stick angle sets the mouse position on a circle directly around the center of the screen
MOUSE_AREA: stick position sets the cursor in a circular area around the neutral position
NO_MOUSE: don't affect the mouse, use button mappings (default)
SCROLL_WHEEL: enable left and right bindings by rotating the stick counter-clockwise or clockwise.
HYBRID_AIM: adds together traditional behavior of a stick with a mouse-like behavior.
The mode for the left and right stick are set like so:
LEFT_STICK_MODE = NO_MOUSE
RIGHT_STICK_MODE = AIM
Regardless of what mode you're in, you can have additional input bound to a partial or full tilt of either stick. For example, you might want to always be pressing LSHIFT when the stick is fully tilted:
LEFT_RING_MODE = OUTER # OUTER is default, so this line is optional
LRING = LSHIFT
Or you might want to always be pressing LALT when the stick is only partially tilted:
LEFT_RING_MODE = INNER
LRING = LALT
For backwards compatibility reasons, there are two extra options for LEFT_STICK_MODE and RIGHT_STICK_MODE that set the corresponding STICK_MODE and RING_MODE at the same time:
INNER_RING: Same as _STICK_MODE = NO_MOUSE and _RING_MODE = INNER
OUTER_RING: Same as _STICK_MODE = NO_MOUSE and _RING_MODE = OUTER
If you're holding the controller in an unusual orientation (such as for comfort reasons or when using a single JoyCon), you can set CONTROLLER_ORIENTATION to reflect how you're holding the controller:
- FORWARD is the default.
- LEFT is for when you're holding the controller rotated to its left.
- RIGHT is for when you're holding the controller rotated to its right.
- BACKWARD is for when you're holding teh controller rotated 180°.
- JOYCON_SIDEWAYS means LEFT for the left hand joycon, RIGHT for the right hand joycon, FORWARD for all other controllers.
Once set, JoyShockMapper will rearrange the stick's X and Y axis data to match your perspective. CONTROLLER_ORIENTATION only affects sticks (including motion stick). It doesn't affect the arrangement of the face buttons, d-pad, etc. Look up Gyro Mouse Inputs section for how to remap gyro axis to mouse axis.
Let's have a look at all the different operations modes.
When using the AIM stick mode, there are a few important commands:
- STICK_SENS (default 360.0) - How fast does the stick move the camera when tilted fully? The default, when calibrated correctly, is 360 degrees per second. Assign a second value if you desire a different vertical sensitivity from the horizontal sensitivity.
- STICK_POWER (default 1.0) - What is the shape of the curve used for converting stick input to camera turn velocity? 1.0 is a simple linear relationship (half-tilting the stick will turn at half the velocity given by STICK_SENS), 0.5 for square root, 2.0 for quadratic, etc. Minimum value is 0.0, which means any input beyond STICK_DEADZONE_INNER will be treated as a full press as far as STICK_SENS is concerned.
- LEFT_STICK_AXIS and RIGHT_STICK_AXIS (default STANDARD) - This allows you to invert stick axes if you wish. Your options are STANDARD (default) or INVERTED (flip the axis). To assign a separate vertical value, provide a second parameter.
- STICK_ACCELERATION_RATE (default 0.0 multiplier increase per second) - When the stick is pressed fully, this option allows you to increase the camera turning velocity over time. The unit for this setting is a multiplier for STICK_SENS per second. For example, 2.0 with a STICK_SENS of 100 will cause the camera turn rate to accelerate from 100 degrees per second to 300 degrees per second over 1 second.
- STICK_ACCELERATION_CAP (default 1000000.0 multiplier) - You may want to set a limit on the camera turn velocity when STICK_ACCELERATION_RATE is non-zero. For example, setting STICK_ACCELERATION_CAP to 2.0 will mean that your camera turn speed won't accelerate past double the STICK_SENS setting. This has no effect when STICK_ACCELERATION_RATE is zero.
- STICK_DEADZONE_INNER and STICK_DEADZONE_OUTER (default 0.15 and 0.1, respectively) - Controller thumbsticks can be a little imprecise. When you release the stick, it probably won't return exactly to the centre. STICK_DEADZONE_INNER lets you say how much of the stick's range will be considered "centre". If the stick position is within this distance from the centre, it'll be considered to have no stick input. STICK_DEADZONE_OUTER does the same for the outer edge. If the stick position is within this distance from the outer edge, it'll be considered fully pressed. Everything in-between is scaled accordingly. You can set the deadzones individually for each stick with LEFT_STICK_DEADZONE_INNER, LEFT_STICK_DEADZONE_OUTER, RIGHT_STICK_DEADZONE_INNER, RIGHT_STICK_DEADZONE_OUTER.
When using the FLICK stick mode, there is less to configure. There are no deadzones and no sensitivity. When you press the stick in a direction, JoyShockMapper just takes the angle of the stick input and translates it into the same in-game direction relative to where your camera is already facing, before smoothly moving the camera to point in that direction in a small fraction of a second. Once already pressed, rotating the flick stick X degrees will then instantly turn the in-game camera X degrees. This provides a very natural way to quickly turn around, respond to gun-fire from off-screen, or make gradual turns without moving the controller.
Since flick stick only turns the camera horizontally, it's generally only practical in combination with gyro aiming that can handle vertical aiming.
Flick stick will use the above-mentioned STICK_DEADZONE_OUTER to decide if the stick has been pressed far enough for a flick or rotation. Flick stick relies on REAL_WORLD_CALIBRATION to work correctly (covered later, as it affects all inputs that translate to mouse-movements). This is because JoyShockMapper can only point the camera in a given direction by making the right mouse movement, and REAL_WORLD_CALIBRATION helps JoyShockMapper calculate what that movement should be. A game that natively implements flick stick would have no need for calibration. Flick stick has a few settings if you really want to mess with it:
- FLICK_TIME (default 0.1 seconds) - When you tilt the stick a direction, how long does it take the camera to complete its turn to face that direction? I find that 0.1 seconds provides a nice, snappy response, while still looking good. Set the value too low and it may look like you're cheating, instantly going from one direction to facing another.
Keep in mind that, once tilted, rotating the stick will rotate the camera instantly. There’s no need to smooth it out*; the camera just needs to make the same movement the stick is. FLICK_TIME only affects behaviour when you first tilt the stick. - FLICK_TIME_EXPONENT (default 0.0) - Some people prefer the flick time to be proportional to the flick angle, and some games don't handle extreme flicks in a short timespan well. This setting scales the FLICK_TIME based on the flick angle. For any value here, FLICK_TIME will always be the time for a 180 degree flick, but smaller flicks are affected: a value of 0.0 means no scaling at all (any flick takes FLICK_TIME seconds), while a value of 1.0 causes the actual flick time to be linearly proportional to the flick angle (a 90 degree flick takes 0.5 * FLICK_TIME seconds). Higher values (over)dramatize the differences between small and large flicks.
- FLICK_SNAP_MODE (default none) - Without practice, sometimes you'll flick to a different angle than you intended. If you want to limit the angles you can flick to, FLICK_SNAP_MODE gives you three options. The default, NONE, is no snapping at all. With practice, I expect players will find this most useful, as surprises can come from any angle. But your other options are 4, which snaps the flick to the nearest of directly forward, directly left, directly right, or directly backwards. These are 90° intervals. If you want to be able to snap to 45° intervals, too, you can set FLICK_SNAP_MODE to 8.
- FLICK_SNAP_STRENGTH (default 1.0) - If you have a snap mode other than NONE set, this value gives you the strength of its snapping, ranging from 0 (no snapping) to 1 (full snapping).
- FLICK_DEADZONE_ANGLE (default 0.0 degrees) - Sometimes you want to prepare for turning quickly without flicking. Pushing the stick perfectly forward is near impossible so you end up turning a little, losing the angle you are trying to hold. This setting creates a deadzone for forward flicks: moving the thumbstick forward within this range will be treated as flicking at a 0 degree angle, basically putting you in rotation mode directly. The value is applied in both left and right directions separately: setting this to 15 creates a total deadzone arc of 30 degrees.
*Developer note: The DualSense and DualShock 4's stick input resolution is low enough that small flick stick rotations can be jittery. JoyShockMapper applies some smoothing just to very small changes in the flick stick angle, which is very effective at covering this up. Larger movements are not smoothed at all. This is more thoroughly explained for developers to implement in their own games on GyroWiki. JoyShockMapper automatically calculates different smoothing thresholds for the PlayStation and Switch controllers, but you can override the smoothing threshold by setting ROTATE_SMOOTH_OVERRIDE any small number, or to 0 to disable smoothing, or to -1 to return to the automatically calculated threshold.
The FLICK_ONLY and ROTATE_ONLY stick modes work the same as flick stick with some features blocked out. The former means you'll get the initial flick, but no subsequent rotation when rotating the stick. The latter means you won't get the initial flick, but subsequent rotations will work.
You can also emulate flick stick with a virtual controller, but it's more limited. Set FLICK_STICK_OUTPUT to RIGHT_STICK or LEFT_STICK instead of its default value of MOUSE. When outputting flick stick to a virtual controller, FLICK_TIME and FLICK_TIME_EXPONENT won't do anything. Instead, the virtual stick will be tilted at its full strength in the desired direction for enough time to complete the flick. This will generally be much less precise than MOUSE mode, but it's still useful. Tune the size of a flick stick flick/rotation by setting VIRTUAL_STICK_CALIBRATION. Ideally, this should be set to the maximum horizontal turning speed of the in game camera in degrees per second.
When using HYBRID_AIM stick mode, the output consists of the sum of the behavior of a traditional stick, i.e. stick position sets cursor speed, as well as the positional behavior, i.e. stick travelling sets cursor travelling. Additionally, there is an 'edge push' feature to preserve the motion speed when pushing the stick to the edge. Moving the stick quickly gives a large output that is dominated by the mouse-like component, whereas moving it slowly gives an output that in more influenced by the stick-like component.
With this input method it is easier to do accurate small movements of the camera while being able to do faster turns than with a traditional stick method as the combined behavior results in a high dynamic range.
This mode shares STICK_SENS*, STICK_POWER, (LEFT / RIGHT)_STICK_AXIS, (LEFT_ / RIGHT_)STICK_DEADZONE_DEADZONE_INNER and (LEFT_ / RIGHT_)STICK_DEADZONE_OUTER with AIM.
It is recommended to keep STICK_DEADZONE_OUTER as small as possible for the best experience. STICK_DEADZONE_INNER matters less, as this mode is very responsive even with a large inner deadzone.
The other settings of this mode are:
- STICK_SENS (default 360.0) - How fast the camera is moved by the position of the stick. Currently this is an arbitrary number and a calibration is not implemented for this. In the future this should represent degrees per second.
- MOUSELIKE_FACTOR (default 90.0) - How fast the camera is moved by the movement of the stick. Like the above, no calibration implemented yet. In the future this should represent degrees per one full travel of the stick from center to full deflection.
- RETURN_DEADZONE_IS_ACTIVE (default ON) - There are two possibly quite different ways this input mode can function. When this setting is set to ON, the mode may feel more like a traditional stick, when its set to OFF, the mode may feel way more responsive but it is difficult to make the output hold still because of the behavior inherent to this input method.
- RETURN_DEADZONE_ANGLE (default 45.0 degrees) - The angle to the center from the current stick position where the output is set to zero.
- RETURN_DEADZONE_CUTOFF_ANGLE (default 90.0 degrees) - The angle to the center where the return deadzone has no effect anymore. Between RETURN_DEADZONE_ANGLE and this, the output slowly returns to normal.
- EDGE_PUSH_IS_ACTIVE (default ON) - Whether or not the mouse-like movement is to be continued when hitting the edge of the stick (entering the outer deadzone). If so, it functions similar to the stick-like component until it is reset either by entering the return deadzone or inner deadzone, but is at most the value at the smallest deflection since the push.
When using the MOUSE_RING stick mode, tilting the stick will put the mouse cursor in a position offset from the centre of the screen by your stick position. This mode is primarily intended for twin-stick shooters. To do this, the application needs to know your screen resolution (SCREEN_RESOLUTION_X and SCREEN_RESOLUTION_Y) and how far you want the cursor to sit from the centre of the screen (MOUSE_RING_RADIUS). When this mode is in operation (i.e. the stick is not at rest), all other mouse movements are ignored.
When using the MOUSE_AREA stick mode, the stick value directly sets the mouse position. So moving the stick rightward gradually all the way to the edge will move the cursor at the same speed for a number of pixel equal to the value of MOUSE_RING_RADIUS ; and moving the stick back to the middle will move the cursor back again to where it started. Contrary to the previous mode, this mode can operate in conjunction with other mouse inputs, such as gyro.
When using stick mode NO_MOUSE, JSM will use the stick's UP DOWN LEFT and RIGHT bindings in a cross gate layout. There is a small square deadzone to ignore very small stick moves.
Finally, SCROLL_WHEEL turns the stick into a rotating scroll wheel. Left bindings are pulsed by rotating counter-clockwise and right bindings are pulsed by rotating clockwise. The setting SCROLL_SENS allows you to change the amount of degrees you need to perform to trigger a pulse. Unlike other sensitivity parameters, a higher value is less sensitive.
# Left stick moves
LLEFT = A
LRIGHT = D
LUP = W
LDOWN = S
LEFT_RING_MODE = INNER
LRING = LALT # Walk
Using the motion sensors, you can treat your whole controller as a stick. The "Motion Stick" can do everything that a regular stick can do:
- MOTION_STICK_MODE (default NO_MOUSE) - All the same options as LEFT_STICK_MODE and RIGHT_STICK_MODE.
- MOTION_RING_MODE (default OUTER) - All the same options as LEFT_RING_MODE and RIGHT_RING_MODE.
- MOTION_DEADZONE_INNER (default 15°) - How far the controller needs to be tilted in order to register as non-zero.
- MOTION_DEADZONE_OUTER (default 135°) - How far from the maximum rotation will be considered a full tilt. The maximum rotation is of course 180°, so the default value of 135° means tilting at or above 45° from the neutral position will be considered "full tilt".
- MOTION_STICK_AXIS (default STANDARD) - Select whether you want to invert the axis. To assign a separate vertical value, provide a second parameter.
- MLEFT, MRIGHT, MUP, MDOWN are the motion stick equivalents of left, right, forward, back mappings, respectively.
- This is also affected by CONTROLLER_ORIENTATION described at the end of the previous section.
The gyro needs to be correctly calibrated for motion stick to work best (see calibration commands below under Gyro Mouse Inputs).
By default, the neutral position is approximately the position the controller is when left on a flat surface. You can set a different neutral position by entering the command SET_MOTION_STICK_NEUTRAL. When this command is executed, however you're holding the controller at the time will be considered the "neutral" orientation.
A common use for the motion sensors is to map left and right leans of the controller. This isn't quite the same as motion stick -- regardless of whether you hold your controller flat or upright, lean mappings should still work the same. You just need:
- LEAN_THRESHOLD (default 15°) - Leaning the controller more than this angle to the left or right will trigger the LEAN_LEFT or LEAN_RIGHT bindings, respectively.
The first thing you need to know about gyro mouse inputs is that a controller's gyro will often need calibrating. This just means telling the application where "zero" is. Just like a scale, the gyro needs a point of reference to compare against in order to accurately give a result. This is done by leaving the controller still, or holding it very still in your hands, and finding the average velocity over a short time of staying still. It needs to be averaged over some time because the gyro will pick up a little bit of "noise" -- tiny variations that aren't caused by any real movement -- but this noise is negligible compared to the shakiness of human hands trying to hold a controller still.
If you have gyro mouse enabled and the gyro moves across the screen (even slowly) when the controller is lying still on a solid surface, your device needs calibrating. That's okay -- I do it at the beginning of most play sessions, especially with Nintendo devices, which seem to need it more often.
If you set AUTO_CALIBRATE_GYRO to ON, JoyShockMapper will try to detect when your controller is being held still or left on a steady surface and calibrate the gyro automatically. This is imperfect, though -- every automatic calibration solution will sometimes interpret slow and steady movement as the controller being held still. This can interrupt you making small adjustments to your aim or tracking slow/distant targets. It's also only a new feature, and we try not to change default behaviour. Also, it doesn't yet give you any settings to tweak its thresholds. For all of these reasons this setting is OFF by default, and it's recommended that you calibrate your gyro manually instead.
To manually calibrate your gyro, place your controller on steady surface so that it's not moving at all, and then use the following commands:
- RESTART_GYRO_CALIBRATION - All connected gyro devices will begin collecting gyro data, remembering the average collected so far and treating it as "zero".
- FINISH_GYRO_CALIBRATION - Stop collecting gyro data for calibration. JoyShockMapper will use whatever it has already collected from that controller as the "zero" reference point for input from that controller.
It should only take a second or so to get a good calibration for your devices. You can also calibrate each controller separately with buttons mapped to CALIBRATE. This is how you using them assuming you use the built-in mappings:
- Tap the PS, Touchpad-click, Home, or Capture button on your controller to restart calibration, or to finish calibration if that controller is already calibrating.
- Hold the PS, Touchpad-click, Home, or Capture button to restart calibration, and it'll finish calibration once you release the controller. Warning: I've found that touching the Home button interferes with the gyro input on one of my JoyCons, so if I hold the button to calibrate it, it'll be incorrectly calibrated when I release the button. If you encounter this, it's better to rely on the tapping toggle shortcuts above for each controller, or calibrate all controllers at the same time using the commands above.
The reason gyros need calibrating is that their physical properties (such as temperature) can affect their sense of "zero". Calibrating at the beginning of a play session will usually be enough for the rest of the play session, but it's possible that after the controller warms up it could use calibrating again. You'll be able to tell it needs calibrating if it appears that the gyro's "zero" is incorrect -- when the controller isn't moving, the mouse moves steadily in one direction anyway.
The second thing you need to know about gyro mouse inputs is how to choose the sensitivity of the gyro inputs:
- GYRO_SENS (default 0.0) - How does turning the controller turn the in-game camera? A value of 1 means turning the controller will turn the in-game camera the same angle (within the limits of two axes). A value of 2 means turning the controller will turn double the angle in-game. Increasing the GYRO_SENS gives you more freedom to move around before turning uncomfortably and having to disable the gyro and reposition the controller, but decreasing it will give you more stability to hit small targets.
For games where you don't turn the camera directly, but instead use the mouse to control an on-screen cursor, a GYRO_SENS of 1 would mean the controller needs to turn around completely to get from one side of the screen to the other. For games like these, you'll be better off with a GYRO_SENS of 8 or more, meaning you only need to turn the controller 360/8 = 45 degrees to move from one side of the screen to the other.
A single GYRO_SENS setting may not be enough to get both the precision you need for small targets and the range you need to comfortably navigate the game without regularly having to disable the gyro and reposition the controller.
JoyShockMapper allows you to say, "When turning slowly, I want this sensitivity. When turning quickly, I want that sensitivity." You can do this by setting two real life speed thresholds and a sensitivity for each of those thresholds. Everything in-between will be linearly interpolated. To do this, use MIN_GYRO_THRESHOLD, MAX_GYRO_THRESHOLD, MIN_GYRO_SENS, and MAX_GYRO_SENS:
- MIN_GYRO_THRESHOLD and MAX_GYRO_THRESHOLD (default 0.0 degrees per second); MIN_GYRO_SENS and MAX_GYRO_SENS (default 0.0) - MIN_GYRO_SENS and MAX_GYRO_SENS work just like GYRO_SENS, but MIN_GYRO_SENS applies when the controller is turning at or below the speed defined by MIN_GYRO_THRESHOLD, and MAX_GYRO_SENS applies when the controller is turning at or above the speed defined by MAX_GYRO_THRESHOLD. When the controller is turning at a speed between those two thresholds, the gyro sensitivity is interpolated accordingly. The thresholds are in real life degrees per second. For example, if you think about how fast you need to turn the controller for it to turn a quarter circle in one second, that's 90 degrees per second. Setting GYRO_SENS overrides MIN_GYRO_SENS and MAX_GYRO_SENS to be the same value. You can set a different vertical sensitivity by giving two values to the command separated by a space, instead of just one.
Finally, there are a bunch more settings you can tweak if you so desire:
- GYRO_SPACE (default LOCAL) - Simple gyro aiming solutions will map one of your controller's gyro axes to your camera/cursor's horizontal axis and one to the vertical axis. That's the behaviour you'll get with JoyShockMapper when GYRO_SPACE is set to "LOCAL". This is simple to implement and leaves no room for misinterpretation, but aiming can feel off as you tilt your controller more and more. If you'd prefer a more advanced reading of the gyro combined with the accelerometer to more naturally handle different controller positions, PLAYER_TURN is the way to go. Or, if you prefer to lean your controller side to side to turn your camera, try PLAYER_LEAN. Finally, WORLD_TURN and WORLD_LEAN account for gravity more strictly than the PLAYER_* options.
- GYRO_AXIS_X and GYRO_AXIS_Y (default STANDARD) - This allows you to invert the gyro directions if you wish. Want a left- gyro turn to translate to a right- in-game turn? Set GYRO_AXIS_X to INVERTED. For normal behaviour, set it to STANDARD.
- MOUSE_X_FROM_GYRO_AXIS and MOUSE_Y_FROM_GYRO_AXIS (default Y and X, respectively) - Maybe you want to turn the camera left and right by rolling your controller about its local Z axis instead of turning it about its local Y axis. Or maybe you want to play with a single JoyCon sideways. This is how you do that. Your options are X, Y, Z, and NONE, if you want an axis of mouse movement unaffected by the gyro. These settings only apply when GYRO_SPACE is set to LOCAL.
- GYRO_CUTOFF_SPEED (default 0.0 degrees per second) - Some games attempt to cover up small unintentional movements by setting a minimum speed below which gyro input will be ignored. This is that setting. It's never good. Don't use it. Some games won't even let you change or disable this "feature". I implemented it to see if it could be made good. I left it in there only so you can see for yourself that it's not good, or for you to perhaps show me how it can be.
It might be mostly harmless for interacting with a simple UI with big-ish buttons, but it's useless if the player will ever intentionally turn the controller slowly (such as to track a slow-moving target), because they may unintentionally fall below the cutoff speed. Even a very small cutoff speed might be so high that it's impossible to move the aimer at the same speed as a very slow-moving target.
One might argue that such a cutoff is too high, and it just needs to be set lower. But if the cutoff speed is small enough that it doesn't make the player's experience worse, it's probably also small enough that it's actually not doing anything. - GYRO_CUTOFF_RECOVERY (default 0.0 degrees per second) - In order to avoid the problem that GYRO_CUTOFF_SPEED makes it impossible to move the cursor at the same speed as a very slow-moving target, JoyShockMapper smooths over the transition between the cutoff speed and a threshold determined by GYRO_CUTOFF_RECOVERY. Originally intended to make GYRO_CUTOFF_SPEED not awful, it ends up doing a good job of reducing shakiness even when GYRO_CUTOFF_SPEED is set to 0.0, but I only use it (possibly in combination with smoothing, below) as a last resort.
- GYRO_SMOOTH_THRESHOLD (default 0.0 degrees per second) - Optionally, JoyShockMapper will apply smoothing to the gyro input to cover up shaky hands at high sensitivities. The problem with smoothing is that it unavoidably introduces latency, so a game should never have any smoothing apply to any input faster than a very small threshold. Any gyro movement at or above this threshold will not be smoothed. Anything below this threshold will be smoothed according to the GYRO_SMOOTH_TIME setting, with a gradual transition from full smoothing at half GYRO_SMOOTH_THRESHOLD to no smoothing at GYRO_SMOOTH_THRESHOLD.
- GYRO_SMOOTH_TIME (default 0.125s) - If any smoothing is applied to gyro input (as determined by GYRO_SMOOTH_THRESHOLD), GYRO_SMOOTH_TIME is the length of time over which it is smoothed. Larger values mean smoother movement, but also make it feel sluggish and unresponsive. Set the smooth time too small, and it won't actually cover up unintentional movements.
Flick stick, aim stick, and gyro mouse inputs all rely on REAL_WORLD_CALIBRATION to provide useful values that can be shared between games and with other players. Furthermore, if REAL_WORLD_CALIBRATION is set incorrectly, flick stick flicks will not correspond to the direction you press the stick at all.
Every game requires a unique REAL_WORLD_CALIBRATION value in order for these other settings to work correctly. This actually really simplifies sharing configuration files, because once one person has calculated an accurate REAL_WORLD_CALIBRATION value for a given game, they can share it with anyone else for the same game. GyroWiki has a database of games and their corresponding REAL_WORLD_CALIBRATION (as well as other settings unique to that game). You can use this to avoid having to calculate this value in games you want to play with JoyShockMapper, or if a game isn't in that database, you can help other players by calculating its REAL_WORLD_CALIBRATION yourself and contributing it to GyroWiki!
For 3D games where the mouse directly controls the camera, REAL_WORLD_CALIBRATION is a multiplier to turn a given angle in degrees into a mouse input that turns the camera the same angle in-game.
For 2D games where the mouse directly controls an on-screen cursor, REAL_WORLD_CALIBRATION is a multiplier to turn a given fraction of a full turn into a mouse input that moves the same fraction of the full width of the screen (at 1920x1080 resolution in games where resolution affects cursor speed relative to the size of the screen).
Before we get into how to accurately calculate a good REAL_WORLD_CALIBRATION value for a given game, we first need to address two other things that can affect mouse sensitivity:
- In-game mouse settings
- Windows mouse settings
Even if REAL_WORLD_CALIBRATION is set correctly, your in-game mouse settings will change how the camera or cursor responds to mouse movements:
- If you are playing with mouse acceleration enabled (a setting only a few games have, and they will usually have it disabled by default), you’ll need to disable it in-game for JoyShockMapper to work accurately.
- Most games have a mouse sensitivity setting, which is a simple multiplier for the mouse input. JoyShockMapper can't see this value, so you need to tell it what that value is so it can cancel it out. You can do this by setting
IN_GAME_SENSto the game’s mouse sensitivity.
For example, for playing with keyboard and mouse, my Quake Champions mouse sensitivity is 1.8. So in my Quake Champions config files for JoyShockMapper, or whenever I use someone else’s config file, I include the line:IN_GAME_SENS = 1.8so that JoyShockMapper knows to cancel it out.
There’s one other factor that some games need to deal with. Windows mouse settings:
- In your Windows mouse settings, there’s an “Enhance pointer precision” option that JoyShockMapper can’t accurately account for. Most gamers play with this option disabled, and it’s preferable for using JoyShockMapper that you disable it, too.
- Windows’ pointer speed setting will also often affect the way the mouse behaves in game, but JoyShockMapper can detect Windows’ pointer speed setting and account for it. This is done with the simple command:
COUNTER_OS_MOUSE_SPEED.
The only complication is that some games aren’t affected by Windows’ pointer speed settings. Many modern shooters use “raw input” to ignore Windows’ settings so the user is free to use “Enhance pointer precision” and whatever sensitivity settings they want in the operating system without it affecting the game. If you’ve used COUNTER_OS_MOUSE_SPEED and realised you shouldn’t have, the commandIGNORE_OS_MOUSE_SPEEDrestores default behaviour, which is good for games that use raw input.
In summary, when preparing to share a configuration file for others to use, please consider whether COUNTER_OS_MOUSE_SPEED should be included. When using someone else’s configuration file, please remember to set the file’s IN_GAME_SENS to whatever your in-game mouse sensitivity is.
Once you've done this, you're ready to calculate your game's REAL_WORLD_CALIBRATION value.
For 3D games where the mouse directly controls the camera, the most accurate way to calculate a good REAL_WORLD_CALIBRATION value is to enable flick stick along with a first-guess REAL_WORLD_CALIBRATION value like so:
RIGHT_STICK_MODE = FLICK
REAL_WORLD_CALIBRATION = 40
Now, in-game, use your mouse to fix your aimer precisely on a small target in front of you. Press your right stick forward, and rotate it until you've completed a full turn, releasing the stick once your aimer is in the same position it started before you pressed the stick.
JoyShockMapper remembers the last flick stick flick and rotation you did, so now you can simply enter the following command:
CALCULATE_REAL_WORLD_CALIBRATION
This tells JoyShockMapper that your last flick and rotation was exactly one full in-game turn, and that you'd like to know what REAL_WORLD_CALIBRATION value you should have. JoyShockMapper will respond with something like, "Recommended REAL_WORLD_CALIBRATION: 151.5" (for example). Now you can verify that everything worked correctly by changing your REAL_WORLD_CALIBRATION setting like so:
REAL_WORLD_CALIBRATION = 151.5 (or whatever value JoyShockMapper gave you).
Now check in-game if this value works by completing a flick stick rotation again. The angle you turn in-game should match the angle you turned the stick.
If you want to be even more precise, you can do more than one turn. If, for example, you complete 10 turns in a row without releasing the stick in order to average out any imprecision at the point of releasing the stick, you can add the number of turns after the CALCULATE_REAL_WORLD_CALIBRATION command:
CALCULATE_REAL_WORLD_CALIBRATION 10
You can do this with non-integer turns, as well, such as 0.5 for a half turn.
For 2D games where the mouse directly controls an on-screen cursor, flick stick doesn't have a practical use in general gameplay, but it's still the most useful way to calculate your REAL_WORLD_CALIBRATION value. Again, make sure your IN_GAME_SENS and COUNTER_OS_MOUSE_SPEED are set as needed, and then we'll start by enabling flick stick alongside a first guess at the REAL_WORLD_CALIBRATION.
RIGHT_STICK_MODE = FLICK
REAL_WORLD_CALIBRATION = 1
Notice that this time, our first guess REAL_WORLD_CALIBRATION value is 1 instead of 40. 2D cursor games tend to have a much lower REAL_WORLD_CALIBRATION value than 3D camera games, and it's better to underestimate your first guess than overestimate, so you can complete more stick turns and get a more accurate result.
For 2D cursor games, one full rotation of the flick stick should move the cursor from one side of the screen to the other. Unlike with 3D camera games, the edges of the screen clamp the mouse position, and will interfere with the results if we try to go through them. When calibrating 3D camera games, it's OK if we overshoot our rotation, because we can still move the stick back the way it came until we precisely land on our target, and it'll work fine. But when calibrating 2D cursor games, overshooting in either direction means that some stick input goes through JoyShockMapper, but the corresponding mouse input is ignored in-game.
So, start by manually moving the mouse to the left edge of the screen, then press your right stick forward but slightly to the right, so as to avoid accidentally going slightly to the left (and pressing against the left of the screen). Now rotate the stick clockwise until you barely touch the other side of the screen, and then release the right stick. As before, you can now ask JoyShockMapper for a good REAL_WORLD_CALIBRATION as follows:
CALCULATE_REAL_WORLD_CALIBRATION
JoyShockMapper will then give you your recommended REAL_WORLD_CALIBRATION. It might be something like: "Recommended REAL_WORLD_CALIBRATION: 5.3759".
You don't have to tell JoyShockMapper whether you're calibrating for a 2D game or a 3D game. Flick stick and other settings rely on a REAL_WORLD_CALIBRATION calculated this way for 3D games, but there's no direct translation between the way 3D games work (in angles and rotational velocity) to the way 2D games work (across a 2D plane), so calibrating 2D cursor games as described is simply convention.
With such a calibrated 2D game, you can choose your GYRO_SENS or other settings by thinking about how much you want to turn your controller to move across the whole screen. A GYRO_SENS of 1 would require a complete rotation of the controller to move from one side of the screen to the other, which is quite unreasonable! But a GYRO_SENS of 8 means you only have to turn the controller one eighth of a complete rotation (45 degrees) to move from one side of the other, which is probably quite reasonable.
JoyShockMapper can create a virtual xbox or DS4 controller thanks to Nefarius' ViGEm Bus and ViGEm Client softwares. The former needs to be installed by the user before the latter can be used. Once installed, you can set which virtual device you desire to create for each connected device using the command VIRTUAL_CONTROLLER = XBOX or VIRTUAL_CONTROLLER = DS4. The default value is NONE, which is no virtual controller at all. Rumble will then work on DS4 controllers, but obviously support is game dependant. Using virtual controllers is most likely to work well only if whitelisting is active (HIDGuardian/HIDCerberus), in order to hide the original controller entry from the game and only expose the virtual one. Funny thing to note is that hiding DS4s with HIDGuardian will also hide the virtual DS4 from ViGEm, since Windows cannot tell the virtual controller form the physical one.
If you have set the virtual controller to the xbox scheme, then the following becomes available to you:
- New digital bindings
X_A, X_B, X_X, X_Y : The xbox face button diamond
X_LB, X_RB : The xbox bumper buttons
X_LS, X_RS : The xbox stick click buttons
X_BACK, X_START, X_GUIDE : The xbox control buttons
X_UP, X_DOWN, X_LEFT, X_RIGHT : The xbox dpad directions
X_LT, X_RT : Digital trigger bindings
# There is no CAPTURE / SHARE (Series X) button binding yet in ViGEm
- New stick mode available
LEFT_STICK_MODE = LEFT_STICK
RIGHT_STICK_MODE = RIGHT_STICK
While these map very simply from your real sticks to the virtual sticks, there are other new stick modes available for giving finer control over a single axis:
LEFT_ANGLE_TO_X
LEFT_ANGLE_TO_Y
RIGHT_ANGLE_TO_X
RIGHT_ANGLE_TO_Y
These will take the stick's angle into account for inputs that are normally only in one axis. For example, steering a car: instead of just moving the left stick left and right for adjusting your steering, rotating it around the edge of the stick will give you more precision and finer control over how hard you're steering. Set up the relevant UNDEADZONEs and UNPOWER for best effect.
These stick modes have inner and outer deadzones, set in degrees:
ANGLE_TO_AXIS_DEADZONE_INNER = 0
ANGLE_TO_AXIS_DEADZONE_OUTER = 10
There's also:
LEFT_WIND_X
RIGHT_WIND_X
These also use the angle of the stick to control the virtual stick in a single axis, but these are relative instead of absolute, and can use a much wider range. This means pointing the stick in a direction doesn't really do anything, but rotating the stick does, letting you wind the stick left or right to adjust the stick position left or right. When you release the stick the virtual stick will quickly pull back to its neutral position. Here are the relevant options:
- WIND_STICK_RANGE (default 900.0°) - This is the total range of winding motion available on the stick. It's from full-left to full-right, but the "neutral" position is in the middle. So the default of 900° means you can rotate the stick 450° to the left and 450° to the right.
- WIND_STICK_POWER (default 1.0) - What is the shape of the curve used for converting the wound position to a stick offset? 1.0 is a simple linear relationship. Larger values will mean rotations are reduced when near the neutral position and increased towards the edge of the range. Smaller values will mean the opposite.
- UNWIND_RATE (default 1800.0 degrees per second) - This is how quickly the wound stick position pulls back to its neutral position when the stick is released. If the stick is only partially engaged, the virtual stick position will unwind more slowly.
For MOTION_STICK_MODE in particular, there are two new options:
LEFT_STEER_X
RIGHT_STEER_X
These will map leaning the controller to the X axis of either the left or right stick. For steering a car, this works better than mapping MOTION_STICK to a stick. But like mapping it to a stick, UNPOWER and UNDEADZONE come into play. Make sure to set MOTION_DEADZONE_INNER and MOTION_DEADZONE_OUTER to suitable values -- they're both in degrees, with the max motion / lean angle being 180 degrees.
- New trigger mode available
# Using analog triggers
ZL_MODE = X_LT
ZR_MODE = X_RT
Using both analog and digital trigger bindings at the same time leads to undefined behaviours. Use modeshift as defined in the next section to disable analog triggers while a digital trigger binding is active.
You will also find a default xbox layout in the GyroConfigs folder that you can use to set up a standard xbox controller configuration. But of course, you can remap buttons elsewhere, or combine them in using the event modifiers, chords, simultaneous presses and such.
GyroConfigs/xbox.txt # load the generic xbox mapping
# Map the dpad as chords of the face buttons
L3 = NONE
L3,N = X_UP
L3,W = X_LEFT
L3,S = X_DOWN
L3,E = X_RIGHT
S,S = X_LS # Double click jump to sprint instead
L+R = X_RS # I don't like to stick click often
MOTION_STICK_MODE = RIGHT_STICK # Gyro driving
ViGEm also the ability to emulate a Dualshock 4 controller. This can allow you to use a switch pro as a DS4 in a game that has this support built in for example. Setting the virtual controller to DS4 enables the use of these features as well. Take note that these names are aliases to the xbox names, so the logs might display the other label.
- New digital bindings
PS_CROSS, PS_CIRCLE, PS_SQUARE, PS_TRIANGLE : The playstation face button diamond
PS_L1, PS_R1 : The playstation bumper buttons
PS_L3, PS_R3 : The playstation stick click buttons
PS_SHARE, PS_OPTIONS : The playstation control buttons
PS_UP, PS_DOWN, PS_LEFT, PS_RIGHT : The playstation dpad directions
PS_HOME, PS_PAD_CLICK : The playstation home and pad click buttons
PS_L2, PS_R2 : The playstation digital trigger bindings
- New stick mode available These are exactly the same as the xbox names
LEFT_STICK_MODE = LEFT_STICK
RIGHT_STICK_MODE = RIGHT_STICK
- New GYRO_OUTPUT mode available
GYRO_OUTPUT = PS_MOTION
- New TOUCHPAD_MODE mode available
TOUCHPAD_MODE = PS_TOUCHPAD
A ds4 can also use the more advanced angle-to-axis stick modes described in the xbox section:
LEFT_ANGLE_TO_X
LEFT_ANGLE_TO_Y
RIGHT_ANGLE_TO_X
RIGHT_ANGLE_TO_Y
LEFT_WIND_X
RIGHT_WIND_X
As well as the MOTION_STICK-specific modes:
LEFT_STEER_X
RIGHT_STEER_X
- New trigger mode available. JoyShockMapper will display the trigger mode as the xbox name : the trigger will still work properly.
# Using analog triggers
ZL_MODE = PS_L2
ZR_MODE = PS_R2
If there is multiple sources of analog data (such as a trigger and a digital binding) the two sources will add up and clamp within the limit of the data. Soft and full pull chords will still be available for use and for the gyro button.
While the virtual controller can't output gyro, JoyShockMapper can convert gyro input to stick output. For example:
GYRO_OUTPUT = RIGHT_STICK
GYRO_OUTPUT can also be set to LEFT_STICK or left at its default value of MOUSE, which means gyro will be converted to mouse input.
Because games tend to do a lof of processing on stick input to turn it into camera movement, you'll want to counter that processing to convert it to a decent camera movement. So far, here are your options:
- RIGHT_STICK_UNDEADZONE_INNER / LEFT_STICK_UNDEADZONE_INNER (default 0) - This will counter the game's inner deadzone. For example, if a game has a deadzone of 0.25 (that's 25% off the stick movement range), very small gyro inputs will convert to a stick radius of just over 0.25 so that the game detects them right away. When gyro output is assigned to this stick and no gyro is detected (if GYRO_SENS is 0, for example), this stick position will be set to the edge of this deadzone. This means you can tweak this deadzone value until you get the largest value that doesn't move the camera automatically to find the exact inner deadzone.
- RIGHT_STICK_UNDEADZONE_OUTER / LEFT_STICK_UNDEADZONE_OUTER (default 0) - Distance from the outer theoretical edge of the stick's range that will be considered "full tilt". Gyro velocity will be mapped to a stick position between _STICK_UNDEADZONE_INNER and _STICK_UNDEADZONE_OUTER.
- RIGHT_STICK_UNPOWER / LEFT_STICK_UNPOWER (default 0) - A power curve is often applied to stick input to give players more with small movements at the cost of less precision with very large movements. If you know what the exponent is, putting it here will counter that power curve to hopefully give you linearly proportional camera control. The default value of 0 does nothing, which is effectively the same as setting it to 1, since that assumes a linear curve.
- RIGHT_STICK_VIRTUAL_SCALE / LEFT_STICK_VIRTUAL_SCALE (default 1) - Use this to scale down virtual stick output. For example, if you're converting gyro to right stick aim (GYRO_OUTPUT = RIGHT_STICK), you'll want a high in game stick sensitivity so you can do fast flicks with the gyro. But you may not want your regular stick aim to be that high. You could set this setting to 0.5 to halve the strength of your stick aiming. JSM will take into account your "UNPOWER" and "UNDEADZONE" settings when calculating this new stick output.
Games sometimes do a lot of other processing to the stick input: easing in, acceleration, direction warping, angular deadzones, for example. JSM does not yet have a way to counter these effects.
Almost all settings described in previous sections that are assignations (i.e.: uses an equal sign '=') can be chorded like a regular button mapping. This is called a modeshift because you are reconfiguring the controller when specific buttons are pressed. The only exceptions are those listed here below.
AUTOLOAD
JSM_DIRECTORY
SIM_PRESS_WINDOW
TICK_TIME
GRID_SIZE
HIDE_MINIMIZED
VIRTUAL_CONTROLLER
Here's some usage examples: in DOOM (2016), you can use the right stick when you bring up a weapon wheel even when using flick stick:
RIGHT_STICK_MODE = FLICK # Use flick stick
GYRO_OFF = R3 # Use gyro, disable with stick click
R = Q # Last weapon / Bring up weapon wheel
R,GYRO_ON = NONE\ # Disable gyro when R is down
R,RIGHT_STICK_MODE = MOUSE_AREA # Select wheel item with stick
Other ideas include changing the gyro sensitivity when aiming down sights, or only when fully pulling the trigger.
GYRO_SENS = 1 0.8 # Lower vertical sensitivity
ZL_MODE = NO_SKIP # Use full pull
ZL = RMOUSE # ADS
ZLF = NONE # No binding on full pull
ZLF,GYRO_SENS = 0.5 0.4 # Half sensitivity on full pull
These commands function exactly like chorded press bindings, whereas if multiple chords are active the latest has priority. Also the chord is active whenever the button is down regardless of whether a binding is active or not. It is also worth noting that a special case is handled on stick mode changes where upon returning to the normal mode by releasing the chord button, the stick input will be ignored until it returns to the center. In the DOOM example above, this prevents an undesirable flick upon releasing the chord.
To remove an existing modeshift you have to assign NONE to the chord. There is special handling for the gyro button because NONE is a valid assignment. Add a backslash to indicate it is the button assignment rather than clearing the modeshift
GYRO_OFF = RIGHT_STICK # Gyro off when using right stick
ZLF,GYRO_OFF = NONE\ # RS does not turn gyro off when ZLF is pressed
ZLF,GYRO_OFF = NONE # oops undo
The touchpad always offers the TOUCH button binding. It will be pressed if there is any touch point active. This binding will overlap with other touch buttons and can be useful to disable gyro for example, or bring up the game map. There is also a dual stage mode setting for the touchpad touch and click: TOUCHPAD_DUAL_STAGE_MODE which can be any mode explained in the analog triggers, where CAPTURE is the full press or click and TOUCH is the soft press. The default setting is NO_SKIP.
The most important setting for the touchpad is simply TOUCHPAD_MODE which will determine the primary functionality of the touchpad. Here are two possible values:
- GRID_AND_STICK - Grid And Stick will create a button grid of equally sized buttons on the touch pad. You have to also assign to
GRID_SIZEthe number of columns and rows of the grid : the product of the two cannot be greater than 25 or lesser than 1. Touch buttons T1-TN will then become available for assignment: they are layed out in order from left to right, from top to bottom. There are also two touchsticks available. See below. - MOUSE - Mouse mode turns the touchpad into a familiar laptop touchpad. Sensitivity can be adjusted via
TOUCHPAD_SENS. Gestures will be added to this mode in future releases. Taps and double taps are already usable viaTOUCH.
Here's an example of grid usage to add some more buttons that otherwise would not be worth putting on a controller
TOUCHPAD_MODE = GRID_AND_STICK
GRID_SIZE = 2 1 # split the pad in two buttons, left and right
GYRO_OFF = TOUCH # disable the gyro when I touch either button
# Bind on clicks
CAPTURE = NONE # Chorded with touch buttons
T1,CAPTURE = F1 # View Help
T2,CAPTURE = F10 # Quick Save
Or a typical touchapd in cursor mode
TOUCHPAD_MODE = MOUSE
TOUCH = LMOUSE' # Quick tap means select
TOUCH,TOUCH = RMOUSE # Double tap for right click
CAPTURE = LMOUSE ^LMOUSE # Or click pad to toggle click (dragging)
A touch stick is a virtual joystick mapped unto the touchpad. As such, a touch stick has and uses all of the familiar binding names and settings, plus one new setting.
TUP, TDOWN, TLEFT, TRIGHT, TRING : The touchstick four directions when in NO_MOUSE mode.
TOUCH_STICK_MODE: Set the touchstick to any stick mode (AIM, FLICK_ONLY, MOUSE_AREA, etc...)
TOUCH_DEADZONE_INNER: Sets how large the area with no output is. There is no TOUCH_DEADZONE_OUTER, as it is replaced with TOUCH_STICK_RADIUS. See below.
TOUCH_RING_MODE: Sets what ring should be used for TRING, either INNER or OUTER.
TOUCH_STICK_RADIUS: Sets the size of the stick, or in other words, the amount of touchpad units to travel to the edge of the stick.
TOUCH_STICK_AXIS** (default STANDARD) - Select whether you want to invert the axis. To assign a separate vertical value, provide a second parameter.
The touchstick center is always the point of contact. As such, one can easily configure swipes by setting a very large touch stick radius and binding values to the 4 directions.
The touch stick differs from other input methods in one particular way. The four stick directions cannot be used as a chord for other buttons, but you can chord the four direction with the grid buttons. As such, you can control two touch sticks at the same time on either side of the touch pad with each having different bindings. The example below showcases the numbers 1 to 4 bound to swipe gestures on the left half of the pad, and 5 to 8 bound to swipe gestures on the right half of the pad.
TOUCH_STICK_MODE = GRID_AND_STICK
GRID_SIZE = 2 1 # Left and Right
TOUCH_STICK_RADIUS = 800 # Use a larger value to use stick as swipe gestures
T1,TLEFT = 1
T1,TUP = 2
T1,TRIGHT = 3
T1,TDOWN = 4
T2,TLEFT = 5
T2,TUP = 6
T2,TRIGHT = 7
T2,TDOWN = 8
There are a few other useful commands that don't fall under the above categories:
- RESET_MAPPINGS - This will reset all JoyShockMapper's settings to their default values. This way you don't have to manually unset button mappings or other settings when making a big change. It can be useful to always start your configuration files with the RESET_MAPPINGS command. The only exceptions to this are the gyro calibration state / settings and AUTOLOAD.
- RECONNECT_CONTROLLERS - Controllers connected after JoyShockMapper starts will be ignored until you tell it to RECONNECT_CONTROLLERS. When this happens, all gyro calibration will reset on all controllers. You can add MERGE or SPLIT to indicate whether you want all joycons under a single controller or separate controllers. The player LED will help you identify whether they are merged or split.
- # comments - Any line or part of a line that begins with '#' will be ignored. Use this to organise/annotate your configuration files, or to temporarily remove commands that you may want to add later.
- JOYCON_GYRO_MASK (default IGNORE_LEFT) - Most games that use gyro controls on Switch ignore the left JoyCon's gyro to avoid confusing behaviour when the JoyCons are held separately while playing. This is the default behaviour in JoyShockMapper. But you can also choose to IGNORE_RIGHT, IGNORE_BOTH, or USE_BOTH.
- JOYCON_MOTION_MASK (default IGNORE_RIGHT) - To avoid confusing behaviour when the JoyCons are held separately while playing, you can have one JoyCon ignored for MOTION_STICK related functions. Since we ignore the left JoyCon by default for gyro, we ignore the right JoyCon by default for motion stick. But you can also choose to IGNORE_RIGHT, IGNORE_BOTH, or USE_BOTH.
- SLEEP - Cause the program to sleep (or wait) for a given number of seconds. The given value must be greater than 0 and less than or equal to 10. Or, omit the value and it will sleep for one second. This command may help automate calibration.
- TICK_TIME (default 3) - The number of milliseconds to wait between between checking the state of connected controllers. Previous versions only sent new virtual keyboard and mouse inputs when there was a new message from the controller, but this made JoyCons clunky on a monitor with a refresh rate higher than 67Hz. Now, all connected devices are polled at the same rate, and you can change it here. The default of 3 milliseconds will give you a polling rate of approximately 333Hz.
- LIGHT_BAR - Set the DS4 light bar to the assigned color. You can assign either a 6 hex digit code precedded by 'x', three decimal values for red, green and blue between 0 and 255, or simply a common color name in capitals and underscore.
- HIDE_MINIMIZED - Some users like having JSM hidden in the notification area. You can hide JSM when minimized by setting this to ON. OFF is the default value.
- README will lead you to this document.
- HELP Will display a list of all commands, all commands containing a given string, or the specific help for all the exact command names given to it.
- CLEAR Remove all text from the console screen.
All of the commands layed out in the previous section can be saved in a text file and run all at once. In Windows, you can also drag and drop a file from Explorer into the JoyShockMapper console window to enter the full path of that file. These configuration files can additionally reference one another. This allows you to group a few settings as a "building block" for your configurations: such as your gyro sensitivity and acceleration preferences.
If you enter a relative path to the file, it should be relative to the folder where JoyShockMapper.exe is located. If however your files don't seem to get picked up, you can manually set where to look for the configuration files by entering the command JSM_DIRECTORY = D:\JSM for example. You can also set that working directory as a command line argument when running JoyShockMapper, which can be done in a shortcut properties. Putting all your configuration files in a synchronized folder allows you to have those configurations across all computers you use for gaming!
What more? There are some configuration files that can be run automatically to streamline your experience.
When JoyShockMapper first boots up, it will attempt to load the commands found in the file OnStartup.txt. This file should be in the JSM_DIRECTORY, which is next to your executable by default. This is a great place to automatically calibrate the gyro, load a default configuration for navigating the OS, and/or whitelisting JoyShockMapper.
This configuration is found in the same location as OnStartup.txt explained above. This file is run each time RESET_MAPPINGS is called, as well as before OnStartup.txt. This file is a good spot to set a CALIBRATE button for your controller and/or set your GYRO_SPACE if you're not using the default value.
JoyShockMapper can automatically load a configuration file for your games each time the game window enters focus. Drop the file in the AutoLoad folder where JSM_DIRECTORY refers to. JoyShockMapper will look for a name based on the executable name of the program that's in focus. When it goes into focus and autoload is enabled (which it is by default), JoyShockMapper will tell you the name of the file it's looking for - case insensitive.
This enables the user to swap focus between your text editor of choice and the game, and each time the configuration will be automatically reloaded with your latest edits (assuming you've saved!). This system also avoids to step on your toes by NOT reloading your configuration if you do change focus between JoyShockMapper itself and the game: any mappings you enter by hand won't be thrown away when you return to your game.
Autoload can be turned off by entering the command AUTOLOAD = OFF. You can enable it again with AUTOLOAD = ON.
Some third-party devices that work as controllers on Switch, PS4, or PS5 may not work with JoyShockMapper. It only officially supports first-party controllers. Issues may still arise with those, though. Reach out, and hopefully we can figure out where the problem is.
But first, here are some common problems that are worth checking first.
-
In some circumstances, the JoyShockMapper console is responding to controller input and the mouse is responding to gyro movements, but the game you're playing isn't responding to it. This can happen when you launch the game (or it's launcher) as an administrator. JoyShockMapper must also be launched with administrator rights in order to send keyboard and mouse events to the game. Windows shortcuts can be set to always run as admininstrator in the properties window.
-
The JoyShockMapper console will tell you how many devices are connected, and will output information with most inputs (button presses or releases, tilting the stick). However, the only way to test that the gyro is working is to enable it and see if you can move the mouse. The quickest way to check if gyro input is working without loading a config is to just enter the command
GYRO_SENS = 1and then move the controller. Don't forget that you might need to calibrate the gyro if the mouse is moving even when the controller isn't. -
Many users of JoyShockMapper rely on tools like HIDGuardian to hide controller input from the game. If JSM isn't recognising your controller, maybe you haven't whitelisted JoyShockMapper. Enter WHITELIST_ADD to do so. You can also add this command to your OnStartup.txt script to do it everytime.
-
Some users have found stick inputs to be unresponsive in one or more directions. This can happen if the stick isn't using enough of the range available to it. In this case, increasing STICK_DEADZONE_OUTER can help. In the same way, the stick might be reporting a direction as pressed even when it's not touched. This happens when STICK_DEADZONE_INNER is too small.
JoyCons and Pro Controllers normally only communicate by Bluetooth. Some Bluetooth adapters can't keep up with these devices, resulting in laggy input. This is especially common when more than one device is connected (such as when using a pair of JoyCons). There is nothing JoyShockMapper or JoyShockLibrary can do about this. JoyShockMapper experimentally supports connecting Switch controllers by USB.
JoyShockMapper was originally created by Julian "Jibb" Smart. As of version 1.3, JoyShockMapper has benefited from substantial community contributions. Huge thanks to the following contributors:
- Nicolas (code)
- Bryan Rumsey (icon art)
- Contributer (icon art)
- Sunny Ye (translation)
- Romeo Calota (linux and general portability)
- Garrett (code)
- Robin (linux and controller support)
As of version 3, JoyShockMapper development is lead by Nicolas Lessard, who was already a long-time contributor and responsible for many of JoyShockMapper's powerful mapping features, autoload, tray menus, and much more. Have a look at the CHANGELOG for a better idea of who contributed what. While Jibb continues on as a contributor, JoyShockMapper is Nicolas' project now. This means updates won't be bottlenecked by Jibb's availability to approve and build them, and Nicolas has final say on what features are included in new versions. As such, make sure you're on Nicolas' fork for the latest developments.
JoyShockMapper versions 2.2 and earlier relied a lot on Jibb's JoyShockLibrary, which it used to read controller inputs. Newer versions use SDL2 to read from controllers, as the latest versions of SDL2 are able to read gyro and accelerometer input on the same controllers that could already be used with JoyShockLibrary, but also support many non-gyro controllers as well.
Since moving to SDL2, JoyShockMapper uses Jibb's GamepadMotionHelpers, a small project that provides the sensor fusion and calibration options of JoyShockLibrary without all the device-specific stuff.
