as Ubi Pictures, the studio became Ubisoft Montpellier. Ancel initially produced Rayman for the Atari ST, a 16-bit personal computer system, working alone on every aspect of the game. Following Houde's arrival on the project, Ancel noticed that public interest in the ST had started to wane and looked to the Super NES CD-ROM, a CD peripheral for the 16-bit Super Nintendo Entertainment System (SNES). However, in 1993 Nintendo abandoned the project before the hardware was produced. Ancel and Houde ruled out a release for the cartridge-based SNES, doubting its ability to handle the large amount of information they wanted to incorporate into the game. The pair switched focus towards newer and more powerful consoles, leaving the SNES version of the game unfinished. This led to the decision to produce Rayman for the Atari Jaguar, a 64-bit cartridge-based system that the team felt could handle the graphics they wanted. In late 1994, magazine advertisements announced the game as a Jaguar exclusive title. Between 1993 and 1994, Rayman originally was submitted to Apogee Software by Ancel, however the publisher was scrapped. Ubisoft decided to also make Rayman a launch title for the North American and European release of the upcoming Sony PlayStation, a CD-based console. Yves Guillemot said the PlayStation edition of Rayman was a way of "beat[ing] Japan on platforming games" by releasing it simultaneously with a new and powerful system. Ancel recalled the number of developers working on the game began to increase, from Houde and himself at its conception, to 100. Later in development, a version for the Sega Saturn was produced. Versions for the 32X (an add-on for the Sega Genesis) and 3DO systems were also announced, but never released. In 1997, an expansion pack entitled Rayman Designer was released for Microsoft Windows, containing a level editor and 24 new levels. A second expansion, Rayman par ses Fans ("Rayman by His Fans"), was released in 1998 and includes 40 fan-created levels chosen by Ubisoft for official release. In July 2017, after an early build of the SNES prototype that had been considered lost was rediscovered, it was released online by developer and programmer Omar Cornut with Ancel's permission. Release By the end of 1995, 400,000 copies of the game had been sold in Europe. This number grew to 900,000 copies sold worldwide after two years. It is also the best-selling PlayStation game of all time in the
