Unlike any of the other known ROMs for the game this one includes a reference list where each block of referenced data is names, ranging from functions to animations.

No game over system has been implemented either, meaning that when all lives are lost the counter cycles back to 99. Only the lives counter and five of the hit points made it into the final game. An icon of an Antitoon is displayed instead of the Tings icon, and apparently it counts and represents how many enemies have been defeated. There is also a very early looking heads-up display which is centered rather than to the left and right, there are more hit points than normal and the word ‘POW’ is between that and the lives counter. Interestingly, Rayman can also perform handstands and attack with his feet, and his fist can be charged up to be more powerful, which is displayed with an icon at the bottom left corner with the word ‘Nova’ next to it. Not all objects have collision detection, such as hunters and Moskito. This version begins with Rayman dropping down in a Dream Forest level, and getting stunned the second he hits the ground, which he does when falling from great heights. Along with this leaked prototype, there is also an early demo version, which displays even more differences between the final version. Two months later, this was leaked to the public along with 19 prototypes or other Jaguar titles. On 25th August 2008, a YouTube video showing an early prototype of the Atari Jaguar version was uploaded. TYPE_SLOPEY_PLAT (254) - unused behavior (DO_SLOPEY_PLAT_CMD).TYPE_VITRAIL (247) - unused behavior for the final boss (DO_VITRAIL_COMMAND).TYPE_CYMBAL2 (169) - unused behavior (DO_2_PARTS_CYMBAL and DO_COLL_RAY_CYMBALE).

TYPE_CYMBAL1 (168) - unused behavior (DO_2_PARTS_CYMBAL).TYPE_GRAP_BONUS (148) - gives Rayman the ability to grab (DoGrapBonusRaymanCollision).
