Got this Game Gear for free but there was no sound and anything on the screen (a common problem) I go to a retro computer club and someone was able to help me replace all the capacitors. The caps that needed replacing was the audio and power boards but we replaced them all anyway. Bought Sonic, Jurassic Park, and Tom & Jerry games to try it out. Not really liking it, the resolution is atrocious and buttons feel dull. Probably will sell when the batteries die but it felt good to bring it back to life.
