Super Mario 64 Disk Version is a prototype disk that was created for display at Nintendo’s Shoshinkai show in 1996, to help promote the 64DD add-on, but never received a general release. The game itself is only slightly different to the cartridge version that had been released in Japan some months prior, with an altered castle theme, the omission of the famous 3D Mario head and a couple of game-breaking bugs in Tiny Huge Land.
