B3313 is a romhack of Super Mario 64 incorporating elements of beta content, urban legends surrounding the game, and popular creepypastas that have spawned from said legends to create a surreal, dream-like experience, with an exploratory aspect similar to games such as Yume Nikki. The game involves players needing to learn the map of the castle over time, and obtain various moves that are initially unavailable to them at the start as the player starts with only the beta moveset. The game finished development with the final version, v1.0.2, in mid-2024. This is now the only version publicly available without using archives.
