There is a youtuber that’s dedicated to finding exploits and glitches in games and his primary focus seems to be on Super Mario 64. Essentially, he explains in a 30 minute video of an over-complicated method of completing a single course in just half of a button press while explaining sub-methods with corny names like Hyper Speed Walking. Just for one star. Again, it’s very complicated, but it works somehow. Watch the video yourself and you’ll understand why this is ridiculous.
