Xpad AVR is a controller emulator for the original Xbox console. It attempts to simulate the HID reports sent from the controller to the console.


You need:

  • An ATMega32u4 (or any AVR with built-in USB) microcontroller (Arduino Leonardo or chinese knockoff)
  • A 16 MHz clock connected to the AVR. (This is standard on Arduinos)
  • WinAVR or a unix with avr-gcc.

To program run make and program it through avrdude:

avrdude -p m32u4 -cavr109 -P /dev/ttyACM0  -b57600 -D -Uflash:w:XpadEmu.hex:i

The above command assumes an Arduino or clone. If you happen to have a vanilla chip, use dfu-programmer.


The project uses the open-source USB stack LUFA to emulate the device.

The included LUFA library has two additions in the HIDClassCommon.h file line 565. Upstreaming these changes is planned, but not until the project is working.
