Lately I've been messing with reverse engineering #panzerdragoonsaga file formats to get at the textures & models for a challenge. Texture (CGB) format wasn't too hard, after reading up some tech docs on saturn development it was fairly basic, except they had no meta data at all!
So while most image file formats contain data on width/height/bpp these were just pure texture data, not even a number of textures in the files nor any barriers. Just 4 bit per pixel indexed colour textures usually with 16 bit per colour (5bit per channel) palettes at the end.
CGB texture files for models usually are accompanied by an MCB file which I assumed was the mesh data... but I couldn't figure that out yet, no easy way of telling what relates to the textures in it without first knowing some textures to find. Catch 22!
