Thank you for the work Szkaradek123. I found an issue with Ayane's face though. The weights are messed up a bit. Like when you rotate the head bone it'll move a large portion of the head but many of vertices don't move with it. Same with other bones. I wish I could check the rest of the faces but I only have Ayane right now (I'll check more when I get home) and report back if any other character has issues (or someone else could check in the meantime). Didn't find any issues with hair or costumes.
Here her face if you want to take a look. http://www.mediafire.com/file/1dx22zf71ylwjz2/face.rar
Also, thank you to Acewell for the texture script!
So 2 things. Firstly, I'm not sure where Darko got Hitomi's face for the upload. I can't find her, Nyo or Momiji's face TMC anywhere in the extracted files. The face TMC uploaded earlier works fine but I dunno where it came from. Maybe we have different versions of the game? Although judging by Darko's links to tools I think we have the same version. Secondly, however, none of the other faces work correctly. They all have the same issue as Ayane's face. I've uploaded all of them here. Still haven't found issues with hair or costumes though. Stages also seem to load fine but I can't be 100% sure because they're pretty damn large with a lot of parts. http://www.mediafire.com/file/kar29bif2ie9920/Faces.rar
