I know a guy selling his gamecube which is the pokemon colosseum version and the game is still sealed. It really is in mint condition. All the leads come with the clear wrapping still on them. The slip cover for the box is also in mint condition. It's the uk pal version by the way.
I know nothing about gamecubes and knew you guys would know your stuff. He just wants a rough idea how much to sell it for. If any of you are interested just let me know also.
