lol, it's obviously no Steuer99 file. I guess it's some kind of Virtual (Hard) Disk which has to be mounted to be opened. I base my theory on the first part of the file's header, which says "VDISK1.0" :P

try to mount with this tool. i cant try now because i'm at work

edit: ok i have tried to mount dat.vdk but doesnt seems to work

Once you can open the client files, you will be able to change all about the physics in game. For example you can fly through the air n that stuff cause there is no synch with the server

CosmosTunes · 05/26/2008, 14:50

well its seems its not that easy. i tried to search a bit on russian sites but there is no solution also. and once you can open the images the editing of that files is another part ^^

djbrazil · 05/26/2008, 18:13

yeah ... it is a virtual disk ... acctualy microsoft has some kind of tool used on vitual machines to open it ... but i had no time to look for it !
maybe if we could unpack the .exe file we could find the source code to read it !
have any1 tried it yet ?

Dammit not long ago uninstalled IDA.x) was pain to find.

It will be pretty difficult to change things in the .VDK files since Requiem.exe have some CRC's.

Here are the results of the PEiD plugin KANAL:

I think this one "CRC16 (rev) [word] :: 003DC430 :: 007DD830" is the bad guy.

I'm curious as to whether or not anyone has decent way of opening the VDK files. I'd like to get into the data files, not to try to tweak things or anything, but just to get into the data to data mine it.

I downloaded IDA (Freeware version) but am not too savvy on what to do. I couldn't get any of them to open up.

Any tips?

dsfgd · 06/11/2008, 01:08

i analysed a little bit this filesystem
it's easy, but not really easy for beginners.

i wrote a little prog which can extract any file inside this VDK's
here a screenshot: (DAT.VDK)

it's really basic and reads only the name + file infos
any directory info is ignored, what means, atm it reads directorys as files.

this is my little File Format info:

Code:

8 Byte = "VDISK1.0"
4 Byte = 00 FF FF FF
4 Byte = File Count (without directory info)
4 Byte = VDK typ ??? don't know
4 Byte = VDK Size (- Header)

Loop (FileCount)
1 Byte = Type (0 = File, 1 = Directory)
128 Byte = Filename/Directory Name
4 byte = FileSize Uncompressed
4 byte = FileSize Compressed
4 byte = an Offset, empty by files, not empty by directorys
4 byte = an Offset which links to another file, don't know atm, it's 0 when this is the last file of directory
X Byte = Compressed Data
Loop until EOF

any file is compressed with Zlib

my prog is not finished and i don't want to release it for now

//edit:

i finished it today, it has fully directory support and it automatically decompress the selected file after extracting.

here the current build:
Screeenshot:

download:

you will need VB6 Runtime or it will not work.
optional: copy Zlib.dll to "C:\Windows\System32" but do this only when it gives you an error on decompressing.

have fun finding hacks, most files are csv so it's easy to edit them.

DeltaX13 · 06/12/2008, 23:33

Can't test it til sunday but it seems you did a really good job mate. Thank you!

david04 · 06/17/2008, 03:02

when try to extract, it said input file corrupted.... -.-

try to copy Zlib.dll to your "C:\Windows\System32\" directory.
