Mario Kart XXL

Mario Kart XXL is a Game Boy Advance tech demo created by Denaris Entertainment 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 consists of a 3-lap trial run on a floating track similar to Peach Circuit, with a layer below the track depicting several beach islands in an ocean resembling Shy Guy Beach. The player plays as Mario, who is rendered in full 3D from an overhead, behind-the-back view. Driving physics are basic: off-road does not slow the kart down, and the Coins present on the track cannot be collected, although Mario can fall out of bounds and into the sea below the track. The camera often zooms in and out automatically, though the player can press to zoom in and  to zoom out manually. Transparent windows showing the lower background layer are present near the beginning and closing sections of the track.

XXL's main menu features two options: "Play" and "Demo", the latter of which, as its name indicates, shows an automatic playthrough of the demo when selected that repeats after finishing. Pressing at any point in either mode returns the player to the main menu.
