Pony Fantasy VI Remake

Well, if it were me going about identifying and fixing this, I would make a patch of your hack thus far, then patch a clean rom and have it do a patch report, then look at all the banks and affected ranges trying to match up and identify anything that looks suspicious. Sometimes I've had to dump clean data back over basically everything in the patch report, until I can narrow down exactly which address is the culprit. It's a b*t*h, but in the long run will help you to revert the damage, whatever it may be.
