List of Mario Kart Wii pre-release and unused content

These are beta elements from Mario Kart Wii.

Beta Elements
The game's original name was going to be Mario Kart X when it was still in development. Also, the designs for Standard Kart S, Standard Kart M, and Standard Kart L were different, as well as the HUD. Also, Boo was supposed to be in the game, but King Boo replaced him.

When all of the files are extracted from this game, a course called "old_mario_gc_b" is found. It is just like GCN Mario Circuit, the fourth course in the Leaf Cup, but the difference is that there is no Chain Chomp, The Pirahna Plants are not in Warp Pipes, and the player's icon goes off of the screen as there is no map. This could be a course used for future tournaments, or it could be a simple debugging stage.
