The code at https://github.com/Cxbx-Reloaded/Cxbx-R ... .cpp#L1339 seems to work.

Yeah but I don't think it's possible to store the raw 256-colour image data in a .dds? From the documentation it looks like you can only store data where each pixel's colour is specified (or data encoded with some sort of DXT compression).

Alright so I've got extraction of DXT1 and DXT5 textures working but not P8 (and they're the only three formats I've come across). Turns out the P8 images are swizzled. It looks like the swizzling/deswizzling code is in the SourceSDK: /****************************************************************...

Great thanks - I'm looking to export to a single format ideally (.dds in this case) but it's probably easier to just put palettised data into a .bmp and use .dds for everything else rather than trying to decompress DXTn data to get it into .bmp form as well.

Is it possible to store a 256 colour image with palette data in a .dds file? Looking at https://msdn.microsoft.com/en-us/librar ... s.85).aspx is doesn't look like it but it's not explicit either way.

As a follow up, the .xpr format is meant to be a standard XDK format but the Counter-Strike Xbox .xpr files don't seem to conform. There is any interesting quote from one of the developers at http://www.ritualistic.com/forums/showpost.php?p=144287&postcount=27 The textures are not stored in the ...

I've got a work in progress tool that can convert to a .dds file (the format is pretty similar to the .vtf file format - texture data seems to be stored the same way, though the low res image data may not be, and there is new fallback image data too - the header is in the Source SDK anyway). Interes...

With some other documentation I was able to work out the structure: struct xprFileData { __int32 iType; __int32 iOffset; __int32 iLock; __int16 iFormat; // one of these bytes is the format, and the other is always empty? byte iWidthComponent; byte iHeightComponent; __int32 iSize; // unused? }; iForm...

Hi. I've been fiddling with rtech_game.dll for quite a while. Now I'm relatively new to reversing so the work doesn't really go that fast. But I managed to find functions that manage data chunks and the actual rpak decoder. So if anyone is interested (cra0?), I can provide functions' file offsets a...

I know it's a little late but does anyone know the .xpr format? There is documentation at http://wiki.xentax.com/index.php/Counterstrike_XBox_XPR which is mostly right but it doesn't give any details about how to get the actual texture information out in a usable form. Slapping a .dds header on the ...

Not sure if anyone saw it but there's some information about the purpose of .rpak and .starpak files in http://twvideo01.ubm-us.net/o1/vault/gd ... eaming.pdf
Looks like they store some sort of texture data for performance.

So I've been trying to extract one of these .vpk files but am having some trouble. This is what I have as the directory entry format. struct vpkDirectoryEntry { unsigned __int32 iCRC32; unsigned __int16 iUnknown2; unsigned __int16 iArchiveIndex; unsigned __int16 iUnknown3; unsigned __int32 iUnknown4...
