In M.U.G.E.N, Rainbow Road has been made numerous times by a variety of creators, with some of those creators creating multiple versions of the stage. Mario Kart 64's Rainbow Road makes an appearance in F-Zero X as the first course of the unlockable Joker Cup, with the tagline of 'Psychedelic Experience'.
As per tradition, Rainbow Road has always been the final course of the Special Cup, excluding those that appear as returning tracks, such as SNES Rainbow Road in Mario Kart 7 and N64 Rainbow Road in Mario Kart 8, which both appear as the final course of their game's respective Lightning Cup, and SNES Rainbow Road in Mario Kart 8, which appears as the second course of the downloadable Triforce Cup. Rainbow Road is a recurring race course from the Mario Kart series, having appeared in every game of the series to date.
