During a fight there are a lot of graphics issue. You have to play for a while, though. Most of the time it happens after ~2 minutes.
I took a look at this yesterday, but haven't been able to figure out the exact cause of the problem. Basically the game is running a DMA operation, but it looks like it's configuring the DMA incorrectly and ends up copying more bytes than it intended, which ends up writing a bunch of garbage to the screen. Will have to take another look later on to try and see if I can find the exact issue.
The same bug is mentioned on a super nt-related repository, and a fix was apparently found and implemented, but unfortunately no details were given as to what the fix was.
Maybe it would be a good idea to verify this on hardware (using a flash cart and not the original cart) to rule out mapping issue?
I didn't have a problem. Here's a video on hardware: https://streamable.com/lkw6wn
Edit:
I played this game for quite a while now and one time I run into a bug on hardware after finishing the first match. One Character disappeared and I couldn't play anymore. So it seems like that this game is indeed not flawless.
