There's also RFL, the actual library for rendering Miis, which is 100% decompiled:
https://github.com/SMGCommunity/Petari/tree/master/libs/RVLFaceLib/include
https://github.com/SMGCommunity/Petari/tree/master/src/RVLFaceLib

(Probably not serious because 1. not made to work with libogc, you'd be the first to use this in a custom project to begin with 2. legality is questionable)
