testing new animatinos

Here's a question, when I change the animations and stats and effects of attacks and skills in ff3usme6.7 and then load up a game, will those changes or should those changes be applied to .srms that i already have?

i ask, bc i'm trying to test out the new blitz skills i've been working on and set the level learnt to 1 for each (sabin being lvl 10) and he only has 2 blitzes when you load the game. The 2 that i can use are the new animations, but I can't test all the other ones to see what
they look like.

I"ve messaged poco about it, as he's been helpful in hte past, but not online atm . So anyone else's input would be appreciated too!

thanks in advance
