Spell animations and stat caps

I have been wanting to know how to insert new spell animations into FE7 but i can’t seem to find a tutorial. Can someone point me in the direction of a tutorial or tell me how to do it step by step? Also i wanted to know if there is a way to increase stat caps past 30 without it wrapping around? Is there a patch for this or something?

Isn’t a tutorial for spell insertion in the Ultimate Tutorial

The spell insertion is in fact detailed in the Ultimate Tutorial. It’s a long chapter that assumes you know a lot of other stuff already but I used it when inserting spells and had success. I would definitely refer to that.
