[Request] Tantra 2 .Dat files

[Rimbros]

Ok this its Tantra 2 files samples in the repository, hope somebody can take a view, the models and textures are stored in big .DAT files but i upload a little .DAT file. thanks.

it uses lzma compression but the dat files are encrypted probably with aes or another block cipher:

Code: Select all

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: Select all

Offset - 397497 (0x610B9) (in DAT)
Uncompressed Size - 743460 (0xB5824)
Compressed Size - 741034 (0xB4EAA)

http://www.mediafire.com/?85ua969igt91pjr

Code: Select all

goto 0xA

for
    4 Bytes - File Offset
    4 Bytes - Uncompressed Size
    4 Bytes - Compressed Size
    8 Bytes - LZMAProp
    String (0x100) - FileName
next

Parsing unpacked SQL something like that

Code: Select all

goto 0xA

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

_microclienturl.sql files game not using.

Lol, hope. Thanks ekey hope u càn made a working inpack for .DAT files or this info help to aluigui to made a goog .dat unpacker. Thanks Man.

Approximately should look like this

Code: Select all

open FDDE sql_unpacked 0

comtype lzma86head

goto 0xA

for i = 0
    get OFFSET long 0
    get SIZE long 0
    get ZSIZE long 0
    get LZMAPROP longlong 0
    getdstring NAME 0x100 0
    clog NAME OFFSET ZSIZE SIZE
next i

But doesn't work.

Code: Select all

- enter in folder D:\Tantra2_Build_4203\launchercfg
- open input file D:\Tantra2_Build_4203\launchercfg\launcherui.sql_unpacked
  0011d1ad 64566      launchercfg/patchui/btn_hot.bmp

Error: incomplete input file number 0, can't read 12719 bytes.
       anyway don't worry, it's possible that the BMS script has been written
       to exit in this way if it's reached the end of the archive so check it
       or contact its author or verify that all the files have been extracted

Press RETURN to quit

I do not know why

[Rimbros]

Maybe aluigui càn tell u why
