FF6 GBA - Leo Survives

[thebearup]

I made a simple hack for FF6 GBA, where Leo survives (replacing Gogo). Only problem is that, when you recruit him, his default name is Gogo. I've tried a bunch of things (FF6 tools, searching for bytes in the rom, etc) but can't find where this default name is stored in the ROM. Any pointers would be appreciated.

Apologies if this is a duplicate post; I tried posting this question last night but getting 500 errors and then it said I had already posted the question (but it didn't appear anywhere in the forum).
Thanks!
