Tile Limit CSA

Well, I was trying to import the sealed sword animation from fe6 to fe8 and I have this classic error:

The image in question is this:

It is weird that an animation from a vanilla game reach the tile limit. I probably may have done something wrong but I wonder what.

It is no wonder considering they are running on different engines.

Really, huh ok, that is enlightening. So, is there anyway to import this?

Copy its routines.

Oh I see well thanks for the answer
