Antinomia: FF6

I was not aware of this project before, but I like a lot of what you've done. Feel free to borrow any portions of Divergent Paths as they become helpful. For example, I've already re-scripted the WoR so that Leo is the letter writer in Zozo, and Cyan is asleep in his bed in Doma. You can see all of it in my beta release.

Two things:
1. If you are not making Celes the main character, then be very careful with the ending cutscene. She's in almost everyone's ending, and her ending will play whether you recruited her or not.
2. Making Mog a recurring guest. It sounds like you're having trouble with characters 0E and 0F getting constantly overwritten in the WoB. There's actually another slot you can shuffle them to, which is 0C. Aside from one of the Moogles, the slot isn't touched until you get Gogo in the WoR. In Divergent Paths, I always have Banon in Gogo's slot, since the Ghosts on the train would otherwise overwrite him. So if you wanted to put Mog in slot 0E, you would just have to have Banon and Ghost #1 get copied to 0C, and then that slot will remain untouched through the whole game.

Alternatively, you could use the Full Roster patch that was a community effort. It sacrifices spell learning from shields and has one desperation attack for all characters, but with those 2 small sacrifices, you get fully playable 15th and 16th characters. In Divergent Paths, I use it to shuffle Umaro over to slot 0F, and I have Leo in slot 0D.

1. Although you're not starting with Celes in WoR, you'll still be required to pick her up (and Edgar and Setzer) before getting the airship, so thankfully there's no conflict with that aspect of the ending as originally written.  However, since Leo has taken Mog's slot, that means Leo gets Mog's portion of the ending, and thankfully I already have an explanation in mind as to why his ending sequence would be to the Moogle theme. 

2. Thankfully Mog isn't recruitable until after you're done getting game-provided guest characters, anyway, so he's still working okay in slot 0E.  The main issue I had with putting him in 0F is that he gets overwritten by Kefka at the Cave to the Sealed Gate if you take him there, and that's literally the only story quest you're capable of taking Guest!Mog to in WoB since you can't get to Narshe before the banquet due to a crashed airship, your party is assigned by the game after the banquet, and once you get the airship back the only place you can go is the Floating Continent, which forces a character-select screen that removes Mog from your party.  Leo's been moved from 0E to 0A at the Thamasa event, so there's no conflict there, either.

I'm grateful for the offer of existing code, but I've already got the whole WoR scripted out and don't want to duplicate too much of what other people already have.  I have a couple of 100% original events planned for WoR, including Leo's re-recruitment which isn't piggybacked off anyone's existing event.  I'm using an expanded ROM for this so I have plenty of event space, and I've already used up the original 244 unused dialogue pointers so wrote my own tool to move the dialogue text out of $CD to allow the pointer table to overflow into it and give me a few thousand extra pointers in the process.
