Some final code requests (and screenshots)

Does anyone know how to stop life spells and phoenix downs from killing certain undead creatures? The only way I have found is to disable the undead box of the monster in question, but that also changes how Gau uses the rage, among other things. For example, it doesn't make any sense for Didalos NOT to be undead, but it's too easy to be able to kill him with a life spell or phoenix down.

Edit: Also, another request: One thing that really bugs me about the General Leo Edition is the old colosseum music being replaced by the Empire music. I understand that federajoe was trying to set the mood with Leo, but I really miss the old colosseum music. Does anyone know how to have the Empire music play until Leo is recruited, then play the old colosseum music?
