While Apple would rather you didn't jailbreak your iOS device, US Congress has deemed jailbreaking legal, so users can pretty much do whatever they want with their phone. Cydia, one of the most popular app stores for jailbreakers, includes a Gameboy Advance emulator called GpsPhone. Using GpsPhone, users can play ROMs of Gameboy Advance games directly on their iPod Touch or other iOS device.

Download the Greenpois0n application from Greenpois0n.com. Connect your iPod to your computer via the sync cable and turn off the device. Open the application, and select "Run as Administrator."
