This is the PSGroove, an open-source reimplementation of the psjailbreak exploit for AT90USB and related microcontrollers.
It should work on:
- AT90USB162
- AT90USB646
- AT90USB647
- AT90USB1286
- AT90USB1287
- ATMEGA32U4
- …and maybe more.
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.
Configuring
Chip and board selection can usually be handled in the Makefile. In particular, update the MCU, BOARD, and F_CPU lines. Suggested values:
Teensy 1.0:
MCU = at90usb162
BOARD = TEENSY
F_CLOCK = 16000000
Teensy++ 1.0:
MCU = at90usb646
BOARD = TEENSY
F_CLOCK = 16000000
Teensy 2.0:
MCU = atmega32u4
BOARD = TEENSY
F_CLOCK = 16000000
Teensy++ 2.0:
MCU = at90usb1286
BOARD = TEENSY
F_CLOCK = 16000000
AT90USBKEY / AT90USBKEY2:
MCU = at90usb1287
BOARD = USBKEY
F_CLOCK = 8000000
Board-specific notes
Teensy boards only have one LED, so it will turn off when the exploit succeeds rather than turn green. Older Teensy 1.0 boards also have the polarity inverted. In general, a LED should do something when the board is powered, and do something different when the exploit works.
Building
On Linux, use the AVR GCC toolchain (Debian/Ubuntu package: gcc-avr). On Windows, WinAVR should do the trick.

Programming
Now program psgroove.hex into your board and you're ready to go. For the AT90USBKEY and other chips with a DFU bootloader preinstalled, you can get the dfu-programmer tool, put your board in programming mode, and run
make dfu
For the Teensy boards, you probably have to use the Teensy Loader software.
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 "InstallPackage Files" menu option in the game menu.
