List of Mario Kart: Super Circuit pre-release and unused content

This is a list of pre-release and unused content for the game Mario Kart: Super Circuit.

Pre-release and unused content
The game's working title was "Mario Kart Advance" which was kept in the Japanese version. Early Nintendo Power screenshots showed that the characters had different, "super-deformed" sprites of bigger heads contrasted by smaller karts. The Banana Bunch and Golden Mushroom items were going to be in the game. The unfinished versions can be seen by using a GameShark code. The Banana Bunch won't do anything, and the Super Mushroom acts like a Mushroom but gives the ability to have infinite boosts even if no item is shown. A Fake Item Box was planned to be in the game but removed for unknown reasons. It has the same functions as a regular Banana.

The HUD was slightly different, though largely recognizable compared to the released version.

Finally, some of the tracks had more detailed backgrounds of an almost painted-quality.
