Yes. If you change an animation using FF3usME, you're changing the ROM. The save data files only hold switch data and apply it to the rom. If you have an endgame save with every skill learned, then you can use that to test the animations. (Though notably some skills are still hard to test like some of Mog's Dances, Setzer's Slots, and monster skills.)
