Official FF6: Beyond Chaos thread (randomizer)

Hello, I am back with a new question.

How can I edit the spellsets in skillrandomizer.py? I am able to change the spells in each set, however if I try to change a name, or add a new spellset following the same format, I will either get an error or the new set will never generate. I can't find if there is somewhere else in the source that validates the names or only pulls from a list of names.

Thanks in advance for the help!
