I've been exploring the Xbox 360 VALVe games, and have found the VTF files to be a special version only used in the console versions (The first 4 bytes of the file are VTFX). I would appreciate any help that can be given to help decompress it, and possibly even convert it to the standard VTF format!...

I have looked into the BSP myself a bit, and found that the actual file has a "LZMA" Header. Is this a compression method?

On the xbox 360, the BSPs are smaller, and don't work in the PC version of Left 4 Dead. The header for the PC Version is "VBSP", but the xbox 360's header is "PSBV". Maybe someone here can figure it out? PC Version BSP: http://www.mediafire.com/?cf80npm3na1sk28 Xbox 360 Version B...
