Hey i don't stream, got my best down to a 2:15 though. I have my copy from when i was a kid and rarely (probably like one in twenty?) after i beat Behemoth and White is cut in half. Also sometimes if i switch weapons in transition screens the game will go to black screen and still play music but cant do anything else. I don't know if these are just normal glitchy stuff or if it's signs my cartridge is getting to old. Any insight?

Switching weapons on transition screens is a known way to soft lock the game. I don't know about glitches following the Behemoth fight though. There are a lot of odd glitches that are dependent on which cart version you have and more importantly which SNES board you are running on.

There are some carts that do have the cloud guy cut in half when he floats away. To my knowledge it doesn't really indicate anything one way or another. I never used to have it happen, but lately I've been noticing it in about half of my runs.

And Zero is right about the transition screen thing. There is 1 frame where if you switch weapons it'll softlock you.
