Just found how to decompress the Xbox compressed files that have the signature "\x0f\xf5\x12\xed".
There is a function in xcompress.lib called XMemDecompressSegmentTD (yeah no results on Google) that is not available in xcompress.h and it's necessary to decompress each chunk because you can't use the standard XMemDecompress.

In the next version of QuickBMS there will be some interesting improvements about Xmemdecompress, including the full automatic decompression of the 0ff512ed and 0ff512ee files and the availability of comtype XMemDecompressSegmentTD.

Try with Google using this keyword (included "):
"0f f5 12"

Venetica, Quake Arena Arcade, Onechanbara Z Kagura, Robotic Notes, Tales of Vesperia, Afro Samurai, probably even WatchDogs.

These files can be easily decompressed with xbdecompress.exe, but I like to implement this stuff natively in QuickBMS
I will not implement the re-compression (for reimporting) because "0f f5 12" is a file format and not a compression, so this is just for having an on-fly decompression if xbdecompress is not available or can't be shared or it's too boring to use it for each file.

I have just fully implemented the handling of these two files inside the private beta version of quickbms.

It's not necessary I can create any sample with xbcompress.exe, I already tested various samples and my implementation seems complete.
