I dont follow speed runners. I know there is a corner hop hack to skip most of the game in Zelda: OoT. Is it common across other speed runs, or is this a reference to that specific bug?

Super Mario 64 has some weird ones like that. I think you slam yourself into a corner walking backwards or something and that gives you super speed to skip through some levels. There is this whole “quantum Mario” stuff in the game.

It's hardly a speed run at 13 hours and 50 minutes, but Watch for Rolling Rocks in 0.5 A presses is an absolute classic.
