I really love those sound patches in Rockman 3 stalker attack's file, although I kind of wish he made the Rockman 3 claw soundtrack a separate sound patch instead of the default one for Rockman 3 stalker attack and made the default Mega Man 3 soundtrack the default one. that being said oh, I do run into issues whenever I try to patch those files onto US Mega Man 3 files.

For a while, I thought the Revenge of gamma soundtrack patch made my own Ridley axe gamma hack obsolete, until I found out that that sound patch completely borked the Shadow Blade by removing its attack boxes. You can still play Mega Man 3 hack with the Wiz sound patches, but you will come across problems. I was wondering if there was a way to remedy those problems, because I really want to play Riley's 4th Mega Man 3 hack with the Rockman 3 burst chaser soundtrack because it goes so well with the stages in that hack. Plus, I kind of wanted to do an edit of that hack by smoothing out some of the more unfair elements of the hack.

Yes, it is possible. (*)

Mostly you'd need to find the same code/data at a different offset and do the same alterations.

(*) When asking any romhacking-related "is it possible" question, the answer is almost always "yes".

Unfortunately, I could never figure out hex editing, but I think I might be able to scrape by if I had a couple of guides to work with.

Hex editing requires you to know the 6502 (or any other language, depending what you're editing) mnemomics and their hex values.

Some nice information can be found here:
