Extended Shoshinkai / Alternative Universe

Extended Shoshinkai refers to a build of Super Mario 64 dated shortly after the Shoshinkai 1995 event, where the game was shown. This version includes rooms not-present in the Shoshinkai build, which were supposedly added in by the Personalisation A.I.

Features
This build features what appears to be a beta iteration of a Tick Tock Clock room, which consists of a door in the left corner, a different yellow wall texture and a painting to what appears to be Tick Tock Clock. The door leads to a hallway tiled in blue with a single door at the end. This door leads to a grayscale castle roof.

This variation of the castle lacks color, the skybox is a grayscale beta texture of some hills and there is no water. Resembling the patent castle, the castle uses the Shoshinkai variant of the brick texture. In front of the entrance to the castle is a sign which reads:"'Please return to the roof. This is not the place for you.'"Inside of the castle is a rendition of the Shoshinkai castle interior with a much drastically different appearance. The carpet appears a much darker shade of red, the wall textures are completely grayscale, the doors are blocked and there is another sign in front of the two steps which reads: "'This world is very different from yours, everything works different. Go outside, find the 5 pipes'"

In the castle grounds near the empty waterfall, there are five grayscale pipes. Another sign appears among the pipes which reads:"'5 pipes, 5 stages, one of them may be doom to you. Depends on what your personal hell is'"Entering the pipe crashes and corrupts the game.

Theorizing
It is theorized that entering one of the pipes leads to a level, yet the only known footage of this build shows that they crash the game. The date given to the build is unknown, however some have speculated that it was created around December 1995.

Video Footage
Footage of the build was uploaded to Youtube by a channel named Gabriel Vera in late-January 2021.
