Don't know much about the game, but a credits warp does exist.

There's not just one video on it eiether, but since I saw it, I might as well post it here:

Hey there! we do know about this one, it is human achievable to get to a glitch screen that way but getting THAT specific glitch screen has not been done by any of our players in real time before. I have gotten the game to glitch me to chapter 6 on everdrive before, but never was able to replicate that on actual cart in a real attempt. it is suspected that certain values need to be set a certain way previously before trying it but no one has labbed it to that level of detail.
