I paid $30 for the Sega Game Gear stuff and the Gameboy games. Sadly both Gamegears need capacitors and I had to replace the Pokemon battery. I used the battery out of the NES Baseball Stars that I had that didn't display correctly. The board was very corroded on the Baseball Stars. Pokemon works perfectly now. The Sega battery packs also need new batteries.
Dang I almost found the same thing, Mine was Black model, 3 games, the hip battery pack and carrying case all for $5.
After testing it out the Game Gear works, great bright picture but no sound.
Tested the battery pack and I can get no life out of it, the charge light doesn't come on.
At least all the games worked great
