Nintendo GameCube (battle course)
From the Super Mario Wiki
The Nintendo GameCube battle course is a battle course in Mario Kart: Double Dash!!. The course consists of a giant Nintendo GameCube floating in what appears to be outer space, and is the simplest course in the game, for it is just a plain surface with glass walls surrounding it with the Nintendo logo; the course is entirely flat except for the small depression in the center of the disc cover opening button. The Nintendo GameCube is purple with a picture of Mario and Luigi in the Red Fire in the center along with the Mario Kart logo.
