If you are coming here to look at getting better video out of a Game Gear, the answer is the McWill LCD replacement. You can swap out the Light diffuser with LED backlights to get more battery out of a GG, but your picture will still be a blurry mess. The McWill replacement LCD, while costly, actually gives you video that is so night and day different that you wont ever be able to play a GameGear again without it.
