Did you know that Rayman was at one time developed for the SNES ?
It seems that it went pretty far (multiplayer implemented and all) before they scraped that and decided to improve it for the SNES−CD.
Then upon seeing the Atari Jaguar and being impressed by its power, they scraped the SNES version and made the game from scratch.
2 years later, it was finally released for the Atari Jaguar, PS1 and Saturn.
Twenty years later, Michel Ancel finally found a prototype and let the world know about it.
He posted a video of the game in action :https://www.instagram.com/p/BL_wNhGALF8/
But there was little hope for it to get dumped... at least that's what we thought.
Then Omar posted on twitter this :https://twitter.com/ocornut/status/881876378056085505
He has found the prototype and he uploaded the ROM online for everyone !
I can confirm that the rom works properly but it is in the early stages, with no enemies...
The ROM he dumped looks VERY similar to Michel Ancel's video uploaded months earlier.
So we can assume that Michel Ancel helped Omar dump it
The graphics look awesome for the SNES but sadly, it's not the prototype with the multi-player mode...
