Onmyou Taisenki PS2 (*.dat)

[Carpaccio]

Hey all! Got a bms script to unpack the archive, and I've got the base files now. Fortunately they're organized by recognizable names! UNfortunately, they've got a kinda weird compression. Can anyone help me figure out the models and textures? This is the specific character I need, in original folder Structure.
