Ah well, I might try looking later (maybe someone with assembly experience will find interest in this).
At the very least, giving Rydia back her White Magic after she becomes an adult is now possible (as well as very easily modifying how the already existing spell lists behave/who gets them), which was one of my main goals; it's just making entirely -new- spell lists that I don't understand.
Hopefully this info is new/found to be useful.
