One Of Super Mario 64's Last Mysteries Has Finally Been Solved After Nearly 30 Years

It's been 28 years since was released on Nintendo 64, but players have finally been able to solve one of its last remaining mysteries. A lone cabin door at the bottom of the game's fourth course, (aka. Snow World) was previously thought to be unopenable from the outside, setting it apart from the majority that players come across in the game which open both ways. The door is clearly fully functional, as Mario has always been able to use it from the inside after diving into a chimney at the top of the mountain and going down a slide, but hitboxes prevent players from making their way back through it after leaving the cabin.

A new video from YouTuber pannenkoek2012 — who previously explained how the game's invisible walls worked in another video — has finally proven that players can get back through the door, sharing a discovery made by speedrunner Alexpalix.

This does require some finesse, however, and isn't as simple as just clipping through a section of the wall on the map, as it is a "" door and actually masks a loading or "" zone, unlike the "" doors in the game that simply open into the next room, so it has to be tricked into thinking Mario is walking into it.

Most «real» doors in can be bypassed with the use of liftable objects.

Super Mario 64's backwards long jump is a glitch that not only lets players skip levels, it's a crucial part of Mario 64's speedrunning scene.

To trick the door, players will need to use the mother penguin found just outside the door. In the level, players will normally need to find and give her baby back to her to receive a Star, but once they've returned the baby, picking it up again will cause the mother to chase them down. In the past, players have been able to use this chase and the hitbox on the mother penguin to force Mario through the cabin wall, but as it doesn't load the room, this sent Mario into a freefall as he fell through the map.

For the most part, Alexpalix's trick does follow this technique, but for a single
