Antinomia: FF6

Okay, a couple of things regarding names and profiles.
NAMES
Names are stored on the character slot, and have little to do with the profile. In event code, you use the 3-byte code 7F XX YY, where XX is the character slot, and YY is the name assigned to the actor profile. This will assign any name you want to any character slot. This also applies to the name change screen. If you evoke the name change screen for character slot 0A, you will be able to change Leo's name at any time, so long as the 7F XX YY command is NEVER AGAIN applied to that character slot. For your hack, you said that you put Leo in slot $0A. Mog occupies that slot in the battle where you get 11 Moogles. If you shuffled Mog over to slot $0E even that far back, then the name will appear as "?????" until you use the 7F commmand.

In Divergent Paths, Leo is named the first time you see him in the military camp outside of Doma. I re-wrote the dialogue from Soldier A and Soldier B to talk about "our general" rather than "General Leo". He has the chat with the soldier from Maranda to establish his overall personality, and then you name him. As soon as you get out of the naming screen, the other soldier runs in from the left, calling him "General <name>" and telling him he's been recalled. All other characters were moved off of slot $0D for the rest of the game, and when you finally get him in the party, I finally assign his profile to slot $0D. One note learned the hard way: any time you are switching back to the main party, you need to change Actor $0A's profile to an empty profile. Otherwise, the guy on the airship who unequips the team will "rescue" Leo's equipment for the rest of the team.

Ah, I was wondering about that.  In my hack, there's a brand new scene incorporated into Terra's flashback when she falls down the mineshaft in Narshe where Leo appears and is named, meaning he gets named prior to the moogle battle.  I think Mog does still overwrite his data in that battle, so that would be why his name gets wiped the next time you see him.  I'll see if switching Mog to a different slot for that battle fixes it.

An issue I ran into, though, was in the battle with Kefka in Thamasa, his name wasn't showing up correctly in the battle dialogue, it was just blank.  I don't know if that's an artifact of the issue with Mog overwriting his name and then swapping the profile back just giving him his default name, but I'd have to change the code at the beginning and play all the way through again to see (or just do a test build where I B2 jump directly to the Thamasa event after the Moogle battle).  Right now I have profile $0A as Leo's permanent party member profile and I think $22 as his unequippable "Guest" profile used for WoB, both of which have the same base equipment and stats.

I haven't had an issue with the airship equipment guy since he does a check if a character has been collected before unequipping them.  I don't set the event bits for Leo to be available in the shop screen or airship until he's recruited permanently in WoR, so he never shows up in that check.  However, I did find that at the end of the Floating Continent there's an event that just goes through and wipes the equipment off every party member regardless of whether you have them or not, so that indeed caused my party to suddenly have the Offering and Aegis Shield in their inventory upon starting WoR.
