Neo Geo Pocket
Similar to the Game Boy and its successors, the Game Boy Color and Game Boy Advance, the Neo Geo Pocket Color does not have a back-lit screen, and games can only be played in a well-lit area. Like the Game.com before it, the Neo Geo Pocket Color uses a CR2032 battery to retain backup memory and keep the clock active, as well as the usual AA batteries to power the system during usage. The Neo Geo Pocket Color has no regional lockout.
