I recently came to the conclusion that I've been overwriting stuff on my ROM. Long story short, I did not repoint my spell association nightmare module properly and ended up writing over parts of the ROM. I tried to fix this by repointing the original section plus the additional bottom portion. This did not seem to fix my problem as my game still freezes up and random black patches appear on maps that normally don't have them.
Is there anyway to fix this? I'd prefer it if I didn't have to start over as I put a lot of work into this.
I can't revert back to old backups as I repointed the spell association module about a year ago when I originally started on this project thinking I did it correct, until recently when it was brought to my attention that I did not. I don't have backups that far back.
I did try to copy vanilla hex from a fresh copy of FE7 to my edited ROM in an attempt to fix it but that didn't work out, hence the freezes and black patches still happening.
