Final Fantasy Hacktics

Hello, there. I have a minor understanding of how things work here (courtesy of Cid III's awesome tutorial), but I still have enough newbie in me that I need help. I am attempting to plant a few sprites from this site on generic characters, and I was wondering if I replace a generic class sprite (say, Squire, for example), will that make every generic character who switches to that class the custom sprite? Thanks go to everyone who replies.

Yes. Though in the formation screen and the battle preparation screen they will still have the squire sprite. You will have to use the Unit.bin editor to change the graphics there.

Could you please tell me where to find this? I don't seem to see it in the download section of this site.

EDIT: Actually, I have another question. Could I replace the sprites of Marach and Rapha with the ones I want? I know I would still have to change their sprites for the party screen, but would they show up as the custom sprites on the battlefield?

You can certainly do that.

To change the formation screen sprite, you need something else, which I can't find right now. Sorry for that.

How do I replace those two with the ones I want? I've searched this site all afternoon and haven't been able to find the answer to that question.
