Wii Mednafen Overview Video
Wii Mednafen 0.1 Update Video
WiiMednafen is a partial port of the Mednafen emulator. [http://mednafen.sourceforge.net/]
Emulators supported:
- GameBoy/GameBoy Color
- GameBoy Advance
- Game Gear
- Lynx
- MegaDrive/Genesis
- Nintendo Entertainment System (NES)
- Neo Geo Pocket
- PC Engine (CD)/TurboGrafx 16 (CD)/SuperGrafx (Fast version)
- PC-FX
- Sega Master System
- Virtual Boy
- WonderSwan
It should be noted that the Virtual Boy emulation included with this emulator is much improved over WiirtualBoy. Most games now run at 100% speed without frame skipping. These improvements are due entirely to Ryphecha (Mednafen) who optimized the core emulation code in addition to eliminating idle loops on a per game basis.
So, a common question might be, "Why release a Mednafen port when a number of the included emulators already exist for the Wii?". After releasing the port of the Mednafen Virtual Boy emulator (WiirtualBoy), my intent was to release a port of the WonderSwan emulator. However, along the way, I decided that rather than replicate a lot of code between projects, I would release a port of Mednafen itself. Also, the possibility does exist for some issues to be resolved with the Mednafen code base. For example, the Lynx port does resolve some of the graphical glitches that exist in WiiHandy (RoadBlasters, Cyberball 2072).
This is a very early release of this port, and as such there are a number of known issues. Further, this emulator hasn't had a tremendous amount of testing so I am fairly certain there are a number of unknown issues as well. Please let me know if you experience any via the Google Code project issues list.
- Save states do not display an associated screenshot.
- PC-FX emulation is extremely slow.
- Loading CD images via SMB (Network) will cause noticeable slowdown.
- Cheats can't be created/edited within the WiiMednafen interface. (They must be created manually or preferably via Mednafen itself).
- Individual cheats can't be enabled/disabled. Currently, all cheats are either enabled or disabled globally (via "Advanced" settings).
- If you have a hard drive that falls asleep, it is highly recommended that you install the application and its support files on an SD card. This ensures that configuration changes and save states will persist properly, even if the drive goes to sleep.
- Many emulator options are not currently exposed, they will be added with subsequent releases.
- Several features of Mednafen proper are not currently supported, they will be added with subsequent releases.
- The front-end is functional but minimal. This is something that may be addressed once I am satisfied with the overall state of the port.
- Some Mega Drive/Genesis games may not run at 100% speed (Thunder Force IV).
To install WiiMednafen, extract the zip file directly to your SD card or USB device (retain the hierarchical structure exactly).
Game ROMs and CD images can be loaded via SD, USB, and SMB (Network).
NOTE The "/wiimednafen" directory (containing saves, BIOS images, etc.) must reside on the same device as the "/apps/wiimednafen" directory (containing the application binary). These two directories must not be split across two different devices. However, game ROMs and CD images can be loaded from any of the available devices (SD, USB, or SMB (Network)).
To function properly, several emulators require additional files (BIOS images, etc.). These files must be placed in the "/wiimednafen" directory.
- lynxboot.img : Lynx boot ROM image.
- pcfx.rom : PC-FX BIOS image.
- syscard3.pce : PC Engine CD BIOS
- disksys.rom : Famicom Disk System BIOS
- gg.rom (Optional) : NES Game Genie ROM image
- gba_bios.bin (Optional) : GameBoy Advance BIOS
WiiMednafen allows for loading ROM and CD images over the network via SMB. To enable SMB support, you must edit the "wiimednafen.conf" file located in the "/wiimednafen" directory and provide values for the following:
- share_ip : IP address of the computer to connect to.
- share_name : Name of the share on the computer.
- share_user : Name of the user to connect as
- share_pass : Password for the user
Please note that loading CD images over the network will cause noticeable slowdown.
There has been some discussion about the types of CD-ROM emulation formats WiiMednafen supports, so I added this section in hopes of clearing up any misconceptions. There are really two types of CD-ROM emulation formats supported by WiiMednafen.
CUE+BIN is the standard format popularized by CDRWin. All of the tracks are contained within a single BIN file. The CUE file indicates where each of the tracks are located within that BIN file. This is the preferred method for WiiMednafen since a properly dumped disk will always work.
In this format, the CUE file refers to one or more external files that represent the different tracks (versus all being in one BIN file). The data tracks are typically represented by ISO files, while the audio tracks are represented by various audio format files. WiiMednefan only supports Ogg Vorbis and MusePack audio formats (MP3, WAV, FLAC, etc. are not currently supported).
Many people have created dumps of PC Engine and PC-FX games in this format in an effort to reduce the overall game size. Unfortunately, many of these dumps leverage the MP3 audio format that is not support by WiiMednafen (or Mednafen proper) due to patent issues.
So, in summary CUE+BIN of a properly dumped game will always work with WiiMednafen. If you want to reduce the size of a dump, you must use Ogg Vorbis or MusePack audio formats. In the future, I may look at adding additional audio formats (FLAC, WAV, etc.) based on the feedback I receive. However, in keeping in alignment with Mednafen proper, MP3 support will never be added.
Double strike (240p) mode is supported for all emulators except Virtual Boy. You can enable double strike globally via "Advanced" > "Video Settings" > "Double strike". The global value can be overridden a per-emulator basis via "Emulator settings" > "Double strike".
By default, double strike is explicitly disabled for all handheld systems. If you want to enable double strike for those emulators, you must set their double strike mode (in "Emulator settings") to either "(default)" (observe global setting) or "Enabled" (explicitly enable double strike regardless of global setting).
NOTE Double strike for PAL-based games (288p) has not been implemented. If there is enough interest, I will look into adding support in a future release.
NOTE Rewind support should be considered "experimental" for the current release. Enabling rewind may cause performance and/or stability issues. If you experience odd performance behavior or periodic crashes, you should consider disabling rewind.
Due to the amount of memory and processing required, rewind support is currently limited to the following emulators:
- GameBoy/GameBoy Color
- Game Gear
- Lynx
- Nintendo Entertainment System (excludes FDS games)
- Neo Geo Pocket
- PC Engine/TurboGrafx 16 (excludes CD games)
- Sega Master System
- WonderSwan (excludes large SRAM sizes: Dicing Knight, Judgment Silversword)
To enable rewind, set the "Advanced" > "Rewind" option to "Enabled".
When rewind is enabled, an additional menu item is displayed, "Rewind buttons", that controls how rewind buttons are added to the different controllers supported by WiiMednafen (Wiimote, Wiimote + Nunchuk, Classic, GameCube).
When "auto" mode is selected, each of the supported controllers are examined in turn to determine if a "(rewind)" button has been explicitly mapped (via "control settings" for the current game). If a "(rewind)" button has not been explicitly mapped for a controller, the "default" rewind button is added automatically (see the "default rewind buttons" table below).
When "manual" mode is selected, rewind buttons must be mapped manually for each controller via a game's "control settings" (available in the "Game-specific settings" menu). You might be wondering why you would ever want to use manual mode versus having the buttons added automatically. One reason is that with the manual mapping mode, a rewind button does not need to be added to each of the controllers. For example, you might be playing a game that requires all of the buttons on the GameCube controller so you don't have one available for the rewind button. You could set the mode to manual and only map the rewind button to the Wiimote. Therefore, you can play the game using all of the GameCube's buttons, and still have the capability to rewind via the Wiimote.

When exiting to the emulator menu after loading a ROM or CD image, two new items will be available, "Game-specific settings" and "Emulator settings".
Emulator settings contain settings specific to the emulator that is associated with the current game. For example, the Virtual Boy emulator settings allows for specifying the display mode to use (2D vs. 3D, etc.).
Game-specific settings contain settings that are specific to the current game. These settings include the ability to provide customized button mappings, etc.

The Virtual Boy emulation included with this emulator is much improved over WiirtualBoy. Most games now run at 100% speed without frame skipping. These improvements are due entirely to Ryphecha (Mednafen) who optimized the core emulation code in addition to eliminating idle loops on a per game basis.
If you do experience any issues, you may want to disable the idle loop "ROM patching". This can be configured globally via "Emulator settings", or on a game-by-game basis via "Game-specific settings".

WiiMednafen supports the ability to switch between different languages via the "Advanced" menu's "Language" option. The language translations files must be located in the "/wiimednafen/lang" directory with each file having a ".lang" extension.
A sample "language" file has been provided as a template, "Hacker.lang". If you create a translation, please contact me and I will include it in the next release. Thanks!
If you are having issues with WiiMednafen, please let me know about it via one of the following locations:
