Edgar glitches in Kefka's end speech

If you change any event data, Zone Doctor will change all subroutines to the CA bank, meaning the game is pretty much unplayable. However, simply opening a rom, making zero changes, and clicking "save" will corrupt the event pointers on the final battle and colosseum maps. It also adds a ton of junk data that no one can figure out. Bottom line, Zone Doctor is an extremely useful view-only tool, but if you have clicked save, even once, your rom is corrupt, and likely your save states. I believe your .srm file should still be useable, if you load from the last save point.
