There are a number of unused tracks found in the Nintendo 64 version of the game left over from the beta. The tracks are Greenwood Village from Diddy Kong Racing, Mizar Race track from Jet Force Gemini, an early version of the White House battle track titled "maze", two battle tracks called "battletest" and "cascade", an empty test map called "mushcan", and an exact copy of the practice stage possibly intended to be used as a battle track. Most of the tracks also feature the Skybox background textures from Jet Force Gemini.
