The following demo was created in early 2004 by Denaris Entertainment Software (founded by Manfred Trenz, creator of the Turrican series). It ended up getting pitched to Nintendo of Europe in order to showcase their dynamic and adjustable perspective view engine featuring dual playfields. Unsurprisingly, it didn’t end up going anywhere.

It primarily consists of a single track featuring various Mario Kart assets. Despite there being a lap counter, the player cannot reach the next lap after crossing the finish line. Similarly, the coins are also unobtainable and the various different terrains do not affect Mario’s speed.

Not only do we have the original binary file for the demo, but we’ve also included the readme file written by Manfred Trenz himself, which includes bits and pieces of information regarding the game’s content as well as an explanation on its controls.

Something else interesting to note is that Mario Kart XXL originally started development under a different titled simply called “R3D-Demo”. This demo doesn’t feature any Mario assets at all, instead opting for a much more plain pre-rendered monster truck. The gameplay itself is virtually identical to Mario Kart XXL, except with a different track layout and other minor differences.
