List of Super Mario 64 pre-release and unused content

This article pertains to the beta elements of Super Mario 64.

Beta elements
This game was originally to be called Super Mario FX, using the FX Chip and was also being planned for the Super Nintendo. In the Beta version, it would've had a numbered health bar instead of the pointed one. Many stages and bars would be different. The Thwomps would also have a scarier look, with round shadows and Mario would have a different jump (one that let him spin around after a triple jump in a way similar to the result of being hit by a Tweester in Shifting Sand Land). Early screenshots also show a tan Cheep-Cheep, not found in the final game. Other screenshots show a Pokey with interestingly different graphics, a skinnier Penguin, and Princess Peach's Castle was different and also used darker shades of color and Lethal Lava Land is different. Mario was voiced differently (possessing a screechy, childlike voice rather than his current Italian accent), and Bowser sounded more tiger-like. There was also going to be a Blargg, which is still in the game's data, that would appear in the Lethal Lava Land stage. Also, in the beta, Big Boo held a key instead of a Star inside of him. The purpose of the keys ware to unlock a variety of the various doors in Big Boo's Haunt - there was even a "key counter". 32 levels were planned for the game, but only fifteen of them made it into the final product. In the game, there are small and large bullys, using two models; small and large bully models, a related species called "Chill Bully" appeared in Course 10: Snowman's Land, it too had a small and large model but only the large model was used, its possible that there were going to be small and large like in Lethal Lava Land but was scrapped. Water mines (with graphics identical to spike bombs) were going to in a water level, this can be seen trough a hack. Yoshi egg graphics are stored in the games code, this too can be seen through a simple hack. VL-Tone ,the creator of Toad's Tool 64 (SM64 level editor) found graphics of what looks like a red, Black and white trampoline, with a yellow ? painted on the side. There are some unused platforms in the game; A flat, checkered platform, resembling the two elevator platforms in Whomp's Fortress. This platform however, is single, it is flatter and it doesn't do anything other than Mario standing on it. Another beta platform like the previous one except it rotates after every couple of seconds. Some unused textures sound in the game can be extracted. One of the textures can be found among the castle paintings is a classic NES painting, this could of been from one of the scrapped levels. Another texture in the game is found in Cool, Cool Mountain, it is much like the ice texture that is used but it has cracks in it. Frames of a flower can also be found in the Lethal Lava Land textures, (similar to the Yoshi egg), It seems like it was going to be used as a background object, however it seems unlikely because it is found in the lava-themed textures. It could be a power up, however, that been said, it resembles Power Flowers in the Nintendo DS remake, though it could just be a coincidence. A debug function stored in the game is the "level select", in this, some of the courses have different names and some symbols can only be seen in the Japanese game. eg. Whomps Fortress is simply called "Mountain".

During a recent interview between Satoru Iwata and Shigeru Miyamoto regarding New Super Mario Bros. Wii, Iwata stated that there used to be a multiplayer function that was scraapped, likely due to hardware limiations. They also stated that one could see Mario and Luigi meet in the corridor. It is unknown however, if this was a plotpoint of some kind, or just the result of the brothers aprroaching each other. This, apparantly, inspired the multiplayer function of said game.

Iwata: Ever since Mario Bros., you've had your heart set on making a multiplayer Mario game. You've tried each time, but it's never quite come together… Even with Mario 64, it started with Mario and Luigi running around together, didn't it? Miyamoto: That's right. The screen was split and they went into the castle separately. When they meet in the corridor, I was incredibly happy! (laughs) Then there was also the mode where the camera is fixed and we see Mario running away, steadily getting smaller and smaller. Iwata: Yes, that's right. Miyamoto: That was a remnant of an experiment we did where Mario and Luigi would run away from each other but you could still see them both. But we were unable to pull it off…
