Hacking Super Mario 64 using covering spaces

Was anyone who played this back in the day on an N64 able to wall-jump on top of the castle?

This reminds me of pannenkoek2012's work on Super Mario 64: SM64 - Watch for Rolling Rocks 0.5x A Presses.

In particular, it makes me think about his "parallel universes" and QPUs.

Too tryhard, just throw gay bowser at the mine and enjoy the game.
