Mario Kart XXL

Mario Kart XXL is a Game Boy Advance tech demo created by Denaris Entertainement Software for Nintendo in 2004. It demonstrates the Game Boy Advance's ability to render and scale/rotate two different background layers.

Mario Kart XXL consist of a 3-laps trial run on a floating track similar to Donut Plains 1, though with a second layer underneath the track depicting several beach islands in an ocean. The player plays as Mario who is rendered in full 3D from an overhead, behind-the-back view. Driving physics are basic, as Mario is not slowed down when going outside the track and the Coins present on the track cannot be picked up, although Mario can fall out of bound and into the sea below the track. The camera often zooms in and out, though the player can also manually zoom the camera, using to zoom in and  to zoom out. Transparent windows showing the 2nd background layer are present near the beginning and closing sections of the track.

XXL's main menu features two options: "Play" and "Demo", which, as its name indicates, shows an automatic playthrough of the demo when selected that repeats after finishing.

Pressing at any point during gameplay or the demo takes the player back to the main menu.
