List of Mario Kart: Double Dash!! pre-release and unused content

These are the beta elements for Mario Kart: Double Dash!!

Beta Elements
The models of the characters are from Super Smash Bros Melee, and Mario and Luigi are seen in this game's only known beta trailer driving separately, each in a simple, blue kart. It was originally called Mario Kart for GameCube, and it is likely that this early build of Mario Kart: Double Dash!! was completely scrapped and redone for the final game, as it looks nothing like it.

A screenshot for the actual Double Dash build showed different textures, speedometer HUD, and racer pictures.
