Also sorry to JARP who intentionally planned to make a video about this first. He ended up being unable to make such a video for a longer timespan now so I prevented it getting delayed even further. You should check out his channel anyways: youtube.com/channel/UClV3w8MVjmd561Rwb6h6QRw

Edit: At 13:40 I meant to say: "You only need to make sure that the way in which you enter and move in this radius is the same every time by doing an easily replicatable sequence of simple inputs."

At 10:40 I mentioned that you would lose all your progress if you had to game over or reset the game to escape a softlock/crash whatsoever, which could be misunderstood. Failing this glitch wil not corrupt save files or anything, of course you will only lose the progress made since you last saved the game, which mostly refers to the items/coins gotten from the RHA.

Updates (as InfiniteVoid316 and aglab2 pointed out):
- The origin of this glitch is apparently that the hat position is written back to the memory after the hat is thrown off of Mario's head
- The coins are only not being added because the initial maximum coin count is 500 and because 769 exceeds this, no more coins are being added to the score. However, the coin count can be increased to a higher maximum later in the game, allowing the coin system to be fully normalized
- The glitched state is caused by the collision map of the game being rewritten after the RHA is triggered, therefore the entrance area becomes out of bounds for the most part and undergoes general collision changes. A death therefore spawns Mario out of bounds and triggeres the infinite-death softlock as well as the majority of the entrance area is blocked from being accessible.
