About the "OP Anime Face" patch

  • Hacking method: FeBuilder
  • Base Game:FE8

I have a question about this patch
Is there a guide for how to use another portrait with this patch ?
Because i don’t know which areas to cut to make it work properly.
For example, if i want to replace it with this portrait (made by Dolkar):
Alen (Child) {Dolkar}
What areas of the portrait should I cut out to put on the image used by the patch ?
Sorry if my question seems difficult to understand.
