Pac-Man on it. And now, thanks to the ipodMame project, you can. A subset of the iPodLinux project, iPodMame aims to bring the MAME game emulator to iPods, allowing owners to play classic games on their audio players. Currently, the emulator is confirmed to be able to run Pac-Man and Ms. Pac-Man on the nano and iPod with video. Other classic games supported by MAME are also supported, so you should be able to play Pengo and -- yes! -- Joust on your iPod.
