    Post Tantra 2 Dat Files

    Web: http://mz.ccjoy.com
    Client Download: http://download.ccjoy.com/mz/client/..._Full_4203.exe

    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

    File table where contained info about size , offset .ect. in SQL file (Compressed and XORed). In DAT files Only Compressed

    launcherui.sql

    Info begin at 0xA offset

    for launchercfg/patchui/bg.png



    Code:
    Offset - 397497 (0x610B9) (in DAT)
    Uncompressed Size - 743460 (0xB5824)
    Compressed Size - 741034 (0xB4EAA)
    http://www.mediafire.com/?85ua969igt91pjr

    Code:
    for
        4 Bytes - File Offset
        4 Bytes - Uncompressed Size
        4 Bytes - Compressed Size
        4 Bytes - LZMAProp
        4 Bytes - LZMAProp
        String (0x100) - FileName
    next
    Parsing unpacked SQL something like that

    PHP Code:
    goto 0xA

    for 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 
    _microclienturl.sql files game not using.
