"Rayman" was initially developed for the Atari ST by Ancel alone. When Houde joined the project, they intended to produce a SNES-CD version and the developers hired animators from a cartoon company that considerably improved the graphics; however, the Super NES CD-ROM Adapter was canceled and the SNES version was cancelled in favor of systems with CD support, leaving this version of the game unfinished but playable. A ROM of an early build of the SNES prototype was later released online by Omar Cornut with Ancel's permission on 3 July 2017.
