I had one as a kid. That thing went through batteries so fast, I messed mine up because of it. I had a battery pack for an RC car, and it looked like a bunch of AA batteries in series, so I took it apart. It worked in my game gear for a little bit until I smelled burning plastic. It melted a part of the battery compartment and my game gear wouldn't take batteries after that, only running off AC power.

My first RPG was on game gear, Dragon Crystal. That was the one where you have a dragon egg following behind you and you had to push your body against the trees to reveal the maze-like path. I don't know if there was an end to that game, but I barely made it to hatching the dragon.

I loved the Sonic games, Castle of Illusion, Columns, the Streets of Rage series.

I had the adapter so I could play my master system games.
