List of Mario Kart Wii pre-release and unused content

This is a list of pre-release and unused content for Mario Kart Wii.

Early builds
As seen in Mario Kart Wii's 2007 E3 trailer, the game has gone under drastic developmental changes before release. Early builds of the game heavily relied on elements from Mario Kart DS (such as a title bearing resemblance to the one found in the previous Mario Kart game). The model designs for many of the vehicles shown in the trailer, such as Standard Kart S, Standard Kart M, and Standard Kart L were slightly different. Interestingly, character animations were very minimal in what was shown in the trailer, where characters wouldn't even move in their vehicles when going off of a trick ramp. Though only Mario Circuit, Wario's Goldmine, Moo Moo Meadows, Mushroom Gorge, Luigi Circuit, DS Yoshi Falls, and GCN Peach Beach were shown in the video, very slight course differences were present in all of the tracks.

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.
