ROM Hack Fates: Replacing a unit's portrait with a custom one?

[Ghostlander]

I was hoping I could learn how to replace a unit's portraits with a custom one I have. I've seen a few personal projects around that have done it, but nothing publicly showing how, or giving a download of any kind.


Anyone out there that knows how to do this sort of thing? I know the facial expression changes would be different images, but for my purposes, they could all just be the same image without me caring.
