Backwards Long Jump

 * Main article: Backwards Long Jump

The Backwards Long Jump (or BLJ) is a glitch which occurs because there is no backward speed limit while long jumping, this glitch is used very often among speedruns of the 16 and 0-star categories.

This glitch was patched in the Shindou version of the game but it is still in the Nintendo 64DD version of the game.

Bugged Fire Texture
The smoke texture that emits from Mario after he has been burned is actually in the incorrect format, making it display incorrectly.

Secret Aquarium

 * Main article: Secret Aquarium

The Secret Aquarium is one of the Castle's many secret stars, found within a small alcove in the Jolly Roger Bay room. It's placement on the iceberg is questionable, since it is a well-known secret level and is mandatory in getting all 120 stars. However, there have been some anomalies relating to the aquarium, such as the darker Aquarium Limbo.

Yoshi's Saddle
Yoshi, who appears atop the castle after collecting all 120 stars, has a different saddle design in Super Mario 64. Notably, the white rim that should be around his saddle is missing. The modelling of Yoshi's saddle implies that the white rim was supposed to be there, but was erroneously coloured red.

Bowser Broke the Door
The door into the Castle Courtyard is bricked up, as if it was broken through and quickly patched up. This has led some people to assume that Bowser broke into the castle through the back door.

Removed Courses

 * See: Removed Areas

Seven course slots are left empty on Super Mario 64's internal level select, and there were many courses planned in development but scrapped. Little to nothing remains of these courses in the idealised copy of the game spread across the internet.

Despite that, some personalised copies of Super Mario 64 contain some of these unused and removed courses.

The End Screen has what appears to be Yoshi standing in front of the table

True Locations of the Painting Worlds
The worlds within the paintings are not tied to the painting, and exist as seperate worlds. This can be seen with Whomp's Fortress, which reappears in Super Mario Galaxy 2 as Throwback Galaxy. Excluding Rainbow Ride's appearance in the Super Smash Bros. series, this is the only time a course from Super Mario 64 has been revisited in another Mario game. It also implies that the painting worlds are situated in completely seperate galaxies to the one where Mario's planet is.

Wet-Dry World supposedly has a brain texture within its files, and the layout of the level itself is meant to be a simulation of a brain.
