The game's theme song was composed by Hironobu Kageyama, best known for his performance of "Cha-La Head Cha-La", the first opening theme song for the Dragon Ball Z anime, while the Goemon Impact theme was composed by Ichirou Mizuki, known for his performance on the Mazinger Z anime's intro. This also subtly references the shows being parodied as Goemon's Sudden Impact form resembles Goku's Super Saiyan form, and the Goemon Impact boss battles feature robots, reminiscent of Mazinga Z's mecha elements.
