Art of fighting SNES

Hello dear friends, how are you? My name is Daniel and I am a video game enthusiast. I really like tinkering and learning about game hacks, etc. I recently learned how to create PCM audio quickly and simply, but I still don't know the part about creating msu-1 rom patches. So if anyone could give some tips, it would be greatly appreciated. And I would also like to make a request: If someone could make an msu-1 of the game Art of Fighting for the Super Nintendo, that would be really cool. Thanks in advance
