PSGroove

This is the PSGroove, an open-source reimplementation of the psjailbreak exploit for non-USB AVR microcontrollers which use the V-USB library.

It is configured to work on:

  • Arduino Mega
  • Arduino Duemilanove

This software is not intended to enable piracy, and such features have been disabled. This software is intended to allow the execution of unsigned third-party apps and games on the PS3.

Cloning

The repository uses the PL3 repository as a submodule. To clone, use something like:

git clone git://github.com/SerialVelocity/psgroove.git
cd psgroove
git submodule init
git submodule update

Configuring

Chip and board selection can usually be handled in the Makefile. In particular, update the MCU, BOARD, and F_CPU lines. Suggested values:

Arduino Mega:

MCU = atmega1280
BOARD = ArduinoMega
F_CLOCK = 16000000

Arduino Duemilanove with ATMega328p chip:

MCU = atmega328p
BOARD = ArduinoDuemilanove
F_CLOCK = 16000000

Arduino Duemilanove with ATMega168 chip

MCU = atmega168
BOARD = ArduinoDuemilanove
F_CLOCK = 16000000

Building

On Linux, use the AVR GCC toolchain (Debian/Ubuntu package: gcc-avr). On Windows, WinAVR should do the trick.

make clean
make

Programming

Now program psgroove.hex into your board and you're ready to go.

Windows: Follow instructions on timwu's repository Linux: Install avrdude and run: make program

Using

To use this exploit:

  • Hard power cycle your PS3 (using the switch in back, or unplug it)
  • Plug the dongle into your PS3.
  • Press the PS3 power button, followed quickly by the eject button.

After a few seconds, the first LED on your dongle should light up. After about 5 seconds, the second LED will light up (or the LED will just go off, if you only have one). This means the exploit worked! You can see the new "Install Package Files" menu option in the game menu.

Notes

A programmed dongle won't enumerate properly on a PC, so don't worry about that.

This branch has a modified payload that adds peek and poke syscalls to the lv2 kernel. A userspace application can use these syscalls to dump out the entire memory space of the kernel, or patch the kernel as it is running.
