Can anyone help me on how to save an edit/character portrait and how to patch a character's AI on Fighter Factory 3?

[AnomalyOfTheW0rld]

So I've been trying to do an edit of Nexus Gaming's Sally Acorn, and it's been frustrating me.

Because every other time I save what I edit for her and try to keep what was there for said edit in Fighter Factory 3 and try to test it in MUGEN (not the test run, the actual game itself) the character won't load and it'll have an error. And every time I load up Fighter Factory to try and test run it again, it can't display the sprites, animations, etc. (it'll say it can't load chars/ff3_0/ff3_0.def, whatever that means.)

I've also been having an issue with the portrait swap, since I want to use a different picture for this edit so that way it doesn't look lazily edited, and it keeps giving it a weird layering and saying that it won't work unless I put a palette for it that matches the index and group.

And I want to improve her combat AI to where she's more consistent and not be a punching bag to everyone, and again, I'm not familiar with that sort of thing.

I'm sorry if this is a LOT to ask. I know how to edit audio/sound files thanks to a tutorial or two, but I don't know jackshit on editing/creating/saving characters compared to everyone else. And the tutorials I have watched a few bits of don't exactly give me a clear picture on what to do.

If anyone here that's still active can help me on this, I'd gladly appreciate that.
