The Cutting Room Floor is a site dedicated to unearthing and researching unused and cut content from video games. From debug menus, to unused music, graphics, enemies, or levels, many games have content never meant to be seen by anybody but the developers — or even meant for everybody, but cut due to time/budget constraints.
Feel free to browse our collection of games and start reading. Up for research? Try looking at some stubs and see if you can help us out. Just have some faint memory of some unused menu/level you saw years ago but can't remember how to access it? Feel free to start a page with what you saw and we'll take a look.
Released: 1988, NES/Famicom
Super Mario Bros. 3 was the last Mario game to be released on the NES. The game introduced such beloved concepts as the Koopa Kids, Super Leaves, and Tanooki Suits.
Fifteen unused levels are tucked away in the game, only accessible through codes and hacking. Along with those levels are unused enemies, graphics, stage palettes, and two unused mini-games. There's even a debug menu!
And in addition to all of that unused content, there are a variety of differences between the Japanese and International versions of the game. The two international revisions contain some interesting differences too! There's a lot to know about Super Mario Bros. 3.
