Final Fantasy Hacktics

I was wondering if there are any unused Effect file .bin in PSX version that I could use to make my own spell effects without overwriting an existing one?

How would I go about finding them? And which ones cause the game to crash?

Thank you in advance.

I want to start by saying that I love this website. I started modding/patching less than a week ago and I have ran into a wall. I read on another post that the sprites in cut scenes are EVTCHR instead of EVGRP, I'm not sure what either of these mean, really, but I do know that I changed the sprites and portraits for Ramza. Every one of them from Chapter 1-4. I noticed afterwards during cut scenes, when Ramza turns certain ways, the sprite becomes broken, and you can see Ramza's original sprite through parts of it. so, my first question is: How would I go about fixing the broken sprite. The second one may be a little easier. I saw a video online of someone who had changed the magic sword attacks (Lightning Stab, Crush Punch, etc.) in both color and they changed the sprites around (the beginning of one attack with the end of another). Could anyone try and explain how they did that? So far the programs I have used to change aspects of the game are the following: FFTEVGRP FFTPatcher, FFTTactext, Shishi Sprite Editor, Graphics Gale Free Edition, MEMCARDREX, and CDPROG. Is there any other programs I need to change these two aspects? After reading a little more about the sprite cut scene problem, I have decided to wait a little longer, so I have a little more experience with changing the game. But I was wondering if the magic sword attacks were covered under Editing Effect File Graphics?
