Nintendo DS (battle course)
From the Super Mario Wiki
The course is located in a starry region of outer space. While the arena does not appear to move around in space, it has no evident technology to keep it in a single place. It is likely that the same method used to suspend the Rainbow Roads and Nintendo GameCube arena is the same used to suspend the Nintendo DS. The course has no obstacles; however, unlike the Nintendo GameCube battle course, there are no walls surrounding the system, so there is a danger of falling off of the side, which results in getting rescued by Lakitu.
The missions 1-5 and 7-6 take place on this course. In both missions, there are gates the player is supposed to drive through.
