List of Mario Kart Wii pre-release and unused content

This is a list of beta elements for the game Mario Kart Wii.

Early builds
The game's original name was going to be Mario Kart X when it was still in development. The designs for Standard Kart S, Standard Kart M, and Standard Kart L were different, as well as the HUD. Coconut Mall was once called Delfino's Mall.

Unused Data
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 Piranha Plants are not in Warp Pipes, and the player's icon goes off of the screen as there is no map. There is also another course called "draw_demo". It is supposed to look like Mario Circuit, but the pointers which are supposed to signify where to look in the file for the textures miss slightly, resulting in a graphical mess-up. There is no lap data or route data, so Lakitu will not appear to turn the player around or tell when a lap is completed.

Sprites have been found depicting icons for a Hammer Bro, Paratroopa, Petey Piranha, and a Mii Outfit C.

Trivia

 * Every character playable in Mario Kart: Double Dash!! either returned playable in this game or has a beta CSS screenshot implying that they were originally intended to be playable in this game.
