Rare footage of a rumored cut fourth floor of the castle, as well as a special mission exclusive to it.

Yoshi's short cameo at the end of Super Mario 64 left many confused, seeing as he seemingly ends his life at the end of his dialogue.

A cancelled promotion tape that would have been given out by Nintendo Power had the game released in December of 1995.

Supposedly, this is footage of a cut level from a stolen beta cartridge intended for E3 1996.

This is the only known recording of the accidental airing of a Super Mario 64 commercial.

Wet Dry World is pretty well known for being surrounded in a foreboding, sort of creepy vibe.

A few copies of the game were packed with a scrapped alternate ending.
