Hello to all, well the new client have different files, all is alocated in .DAT, maybe someobody can take a look into files, I upload some samples.

thanks aluigi for check .DAT, he say it uses lzma compression but the dat files are encrypted probably with aes or another block cipher, but is a file for configs,etc not for models,textures, so think DAT using different key for models,textures,sounds, anyway here samples of sounds,textures and models.

Scan of aluigi:

Code:

---

comtype lzma
get EXT extension
if EXT == "dat"
    print "encryption not supported"
elif EXT == "ccdat"
    print "encryption not supported"
else
    get SIZE long
    savepos OFFSET
    get ZSIZE asize
    math ZSIZE -= OFFSET
    get NAME filename
    string NAME += "_unpacked"
    clog MEMORY_FILE OFFSET ZSIZE SIZE
    filexor 0x10
    log NAME 0 SIZE MEMORY_FILE
    filexor 0
endif

Parsing unpacked SQL something like that :)

PHP Code:

---

goto 0xA

for i = 0
    get OFFSET long
    get SIZE long
    get ZSIZE long
    get LZMAPROP long
    get LZMAPROP long
    getdstring NAME 0x100
    //log NAME 0 0
    print "%NAME%"
next i
