Retro Gaming just got Micro-sized with the Super Micro Asteroids Keychain Gamer from HyperMegaTech! Small enough to fit onyour keys and go anywhere but large enough to be playable. Features three great Atari games - Asteroids, Gravitar and Yars Revenge. 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).
