Need Some Help

Okay update:

I tested it multiple times and it doesn't work =/

I spent the last few days trying to make it work. Just so I can be clear if I'm doing it correctly:

make sure rom / xkas / etc. is in the same folder. Use Cmd prompt to apply them via: "xkas sketch-control.asm [insert rom name here] then press enter.

It doesn't give me an error, so I assume things are fine.

When I applied the basic Sketch one for spell A9 - the game freezes, despite the character who has the command not being in the party (I gave said command to Locke because it's easy to test as his recruitment is quick) so Terra is in the mines and the battles freeze. Ugh.

Then I tested the second one (separately) and made sure to put in the third spell I needed: but then the battles completely glitch out as if I was using the sketch glitch.

Some thoughts: I've tried to look it over and see what could be the problem. The only thing I could come up with is the targeting / whatever may be off? I briefly dabbled in hacking SMRPG and in that I found that if you try to edit spells / change things around the code can be tricky with like positioning and what not. So is it at all possible that because Sketch is so different than the Lullaby spell I'm replacing it with (likewise for Control and those rain spells) that the game is freaking out?
