Retro Gaming just got Micro-sized with the Super Micro Centipede Keychain Gamer from HyperMegaTech! Small enough to fit onyour keys and go anywhere but large enough to be playable. Features three great Atari games - Centipede, Millipede and Crystal Castles. The 2"" Rgb screen allows maximum playability, along with a volume control for just the right amount of sound makes this more than a novelty. Requires 3x Aaa batteries (not included).
