Final Fantasy Hacktics

I'm fairly new to this hacking stuff (I know, said a million times).

I just picked it up about 3 days ago and I've already edited every job class in the game in some way (rebalanced so Physical is a bit weaker, and dual wield is weaker).  The only thing I can't figure out is how to edit these formation images, and I'd also like to add more than the base number of classes if possible.

I have CDprog and already extracted UNIT.BIN and WLDFACE.BIN, and I have the FFTEVGRP to save the images.  The part I'm confused about is how do I open the palettes and whatnot of my .SPR files?  Is there another program I need?

Thank you in advance for your help.

You're doing it wrong, lol.

Read Celdia's Formation Sprite tutorial (also said a million times)

You don't use .SPR files, you will use .BMP files and screenshots
