There is a well-known bug in the Famicom version of this game allowing the player to reach levels such as World K-1 by switching quickly to Tennis, doing things to set memory slots, and switching back to Super Mario Bros. I theorize that there might be a way to use this to warp to 8-4 very early. Further study is definitely required, but this might save minutes in the Any% run. The question is whether this is allowed as it involves switching to Tennis to work. Is switching games midrun like that allowed?

It looks as if the run has a lot of clips, though.

Would it be possible to have an Any% Glitchless category in this game?

The WR has a lot of glitches, though.

Would it be possible to add a Super Mario Odyssey World Peace Current Patch category to Super Mario Odyssey?
