Thread: Tantra 2 Dat Files

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

sorry check first topic.

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)

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 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 


_microclienturl.sql files game not using.
