An expansion kit was released in Japan for the game to be used with the Nintendo 64DD. Players could create custom tracks, custom vehicles and it featured a new improved soundtrack and access to new cups and new vehicles: the Super Falcon, Super Stingray and Super Cat. Even though it wasn't released outside of Japan due to the commercial failure of the Disk Drive, the expansion's data can still be found in the game's files.
In the Virtual Console version of the game, there's a fault that causes textures to appear differently. This is most noticeable in Sand Ocean 1, where there's a bright section of pipes not seen originally.
The game was released 3 months late in the U.S. due to Nintendo's policy of attempting to release first party Nintendo games evenly spaced out throughout the year.
The game's music was compressed down to monaural to save space, with ambient sound effects being used to produce a stereo experience.
The machines with color-specific names despite their names can have their colors changed via pressing the R or Z buttons on the Settings screen before starting a race as with any machine. The only machine to retain its signature white color to be consistent with its name no matter what color the player changes the outer body of it to is the White Cat whose default color is purple.
