Boulder Manipulation
Boulder Manipulation is a strategy in Super Mario 64, which can then be used to collect the star "Watch for Rolling Rocks" in 0.5 A presses.
To do this, the player must perform a series of precise inputs to position the boulder in a specific location, and then they must use Parallel Universes to manipulate the game's memory and change the position of the boulder in such a way that allows collecting the star without using a full A press.
This strategy is only viable in Hazy Maze Cave, as it is the only level with boulders.
