I've been working on a romhack which involves a reclassing of most classes, Eirika is a mage in this and I changed the rapier into aircalibur (or air cutter, as I named it), but i'm having trouble with the BGM kill and I don't know how to fix it. I've heard about a patch, but I can't find it anywhere.
Could someone tell me how to fix it, or hand me the patch?
