Ah yes, I've got one of those. It's torquiose, durable, easy to use, and I love it! I think it's much easier to use than the GBA. I have a few things for it as well... I've got litlle thing you snap on that turns the D-Pad into a Control Stick, and it makes the A and B buttons a bit bigger. I also have a portable battery handle thing. So pretty much if you don't have any batteries you snap this into the battery slot and you can use your GBC! (It also has handles on the sides.) I've got one ofthose cables for hooking three GBCs together, but I never could use it since none of my friends had GBCs...
I've got several games for it as well:
Space Invaders!
Project S-11
Some TJ Javin game
Some skateboard game
A Godzilla game
I can't remember the names becuase I can't find the games.
I also have a case to keep my GBC, games, and things inside.
I love my GBC! <3
