I have a Game Gear for sale with Sonic the Hedgehog 2 Sonit & Tails, World Series Baseball, offiicial carry case, system instructions in Englich & French, Sonic 2 instructions and sega poster one side shows game screen shots and hardware the oyher side shows Jurassic Park. System works perfectly. The screen has some minor scuffs on it. It has both battery covers. The only thing it is missing is the little plug that goes over the EXT connector. I'm asking $25 for it but I will also take trades. Pm me if interested. Thanks Here's a pic
