Changing Active Character slots?(FF6Adv)

I actually spent some time fiddling with Cheat Engine and did manage a workaround to the problem actually. I found where Gogo's saved, then put a freeze on everything on him. Once the time came to be replaced with Cosmog, the mass freeze kept it from doing it. I don't know if Cheat Engine is a proper hex editor, but it worked well enough for this instance at least.
