Replacing Gogo with Daryl

Yeah, you can use FF3USME to change action commands, and you can actually give them any four you like. Gogo is the safest to play with this, because the magic menu is explicitly set not to allow the equipping of an Esper. Without hex edits, giving Blitz, Swordtech, Lore, or Dance won't alter who is required to learn those abilities.

Neither Gogo nor Umaro have their own magic list (unless you're using the MMMMMagic patch). Thus, if either of them is allowed to learn any percentage of a spell, it will dangerously overwrite other data in the RAM. Gogo is the easier of the two to prevent this, as the game is already set up to prevent the equipping of an Esper.

There are a few other things you'll need to do, though. You'll have to prevent the selection of commands from Gogo's status menu, or limit the number of commands available to choose (which can be done by checking off the "Can be used by Gogo" box on various commands in FF3USME's battle editor. Note blocking too many commands will cause graphical ick in the status menu).

I personally turned off all of Gogo's special menu calls with this Hex change.

Code:

C3/225E:    C90C    ====>    C9EA       CMP #$0C    ====>    CMP #$EA       (Gogo changed to actor 234, who is hopefully never called)

But I can't speak to what other effects that might have had, as I gave Gogo's special magic properties to Umaro through other hex edits.

One other thing to keep in mind... if you don't do any event edits, your Daryl will only have two lines, which will be the same regardless of who speaks with her: one upon recruitment and one on the Falcon. EDIT: Oh, and unless you do some creative repointing and hex edits, the ending will still say "Gogo". There's a tutorial on the wiki to change ending names, but it doesn't go into extending short names, so Gogo only has four letters to work with.
