I'm trying to extract textures from Rayman 2 for Dreamcast. They're in the PVR format, but it seems they are compressed.
I extracted the textures from an archive with a "LZSS" header - so that's why I think they might be LZSS-compressed.
Any help?

Here's my script for the archives, some example archives and some example compressed PVR files: https://app.box.com/s/xi2u1i35ww7fdubs7zxz
Many thanks!
