[FE6] Speed up magic animations

The spell animations in FE6 tend to be significantly slower than in FE7 and 8, especially in the case of Dark Magic, despite being the same animations in all other regards. Is there any quick, easy way to just copy over the speed of the animations from FE7+8 without having to mess with tilemaps or wading too deep into ASM or anything like that? As I recall, somebody has made something like this before, but I’ve had a hell of a time actually finding it, and it’d be a nice little quality-of-life patch to have made.
