Final Fantasy Hacktics

I've been using Darthatron's job editor to change the jobs and sprites of the classes available, but I have noticed that i cannot change Marche's sprite(I want to make his sprite Mewt). Is there an editor created that can do the job?

- I'm new to the community so I apologize if I have not followed any guidelines

To my knowledge, the only tool he has regarding sprites lets you view them, not change them.

What i mean by 'change' is that using FFTA_Job I can replace the soldier sprite with prince mewt so when he appearrs in battle he is prince mewt(though it doesnt change the portrait)
