Forgive my English :)
I found some files pvr that the tool failed to extract, can be another structure.

Hi there,
The Sonic Riders PC PVRs are actually an Xbox variant of the PVR format (i call them XVR, I don't know if there is an official name for these). Needless to say there's no support for them at the moment. You may have success extracting them out from the Gamecube version of the game.

As for the Rayman 2 ones, they look like some sort of compressed archive containing multiple PVRs in them. It looks like it's compressed with the LZSS compression format but with a different header. Puyo Tools should be able to decompress these if replaced with a more standard header.

My goal is to translate Sonic Riders and find Graphics rayman.
Currently I use PuyoTool to extract Sonic 2 Advenure PVR/PVM/PRS

Very thanks for the info, I'll try the Gamecube version :)
I'll research more on LZSS header and test if I can extract some of them, as I could tell, so you can implement to your tools when you want.

Sorry my English, I used a translator (I'm from Brazil)
Bye

Sorry my English
The Sonic Riders images are compressed with DXT3 / DXT5, as you can see in this image:

The text should be to the images, the following image shows a seemingly random sequence, but in fact are the letters used in without repeating source (like Sonic Unleashed PS2 where the first letter is equivalent to 0x00000000, the second = 0x00000001 etc. ..).
Ex: "good night git developers"
"god nihtevlprs"

I hope it's a lot of help, and I will give more details when I get more
