This is a fork of burks10 Arduino-SNES-Controller meant to work with a SEGA Genesis/Mega Drive 3 button controller.

1. Install the Drivers by running to UnoJoy/UnoJoyDriverInstaller.bat
2. Open the code located under genesis/genesis.ino and upload it to your Arduino. 3.The Arduino UNO R2/R3 uses a MEGA16u2 chip to upload sketches to memory.

• In order to be recognized as an HID USB device, we must flash the 16u2 chip with some custom firmware.
• To do this on the Arduino R3, short the 2 pins closest to the USB port to enter DFU mode. From there, run UnoJoy/TurnIntoAJoystick.bat.
• Now that you have reflashed the Arduino, unplug it from the USB and re-plug it back in. You are now running the arduino as a joystick.

Be sure to checkout UnoJoy for their awesome library/drivers that made this project possible.

Thanks to burks10 for the original code, you should check him out.
