Re: Call of Duty : MW2 fast file
there is a zlib block in the middle which contains the 2 files I have attached.
the rest of the data is unknown, not xor/rot with a fixed byte and if it's compressed it uses an unknown algorithm

You do not have the required permissions to view the files attached to this post.
Re: Call of Duty : MW2 fast file
thx. How u can extracted them ?
previous fast file version contains 12-bytes header and zlib archive "78 DA"
But now in this version I didn't know how to extract them. Now .ff have 13 (??) bytes header and no zlib bytes

Re: Call of Duty : MW2 fast file
I simply extracted the first block at offset 0x4015 through a scanning with offzip.
then I opened the extracted file and noticed it had other zlib blocks in it and so I did another scan and renamed the files using the names found in that file before the zlib blocks.

Re: Call of Duty : MW2 fast file
ok, I try.
I have used offzip for the job.
I didn't know what type of data was contained in the file so I launched offzip in scan mode for checking if there was a zlib block somewhere:and it reported a block at offset 0x4015 so I launched it in scan+extract mode to dump it:
now I opened the obtained file 00004015.dat with a hex editor to check what it contained and I noticed the 0x78 byte after the first filename "default_mp.cfg" so I simple did the same as before launching offzip with -S and then -a for extracting the compressed zlib blocks.
the last step was renaiming the two files using the names found in that file.
that's all

Re: Call of Duty : MW2 fast file
if you watch in 00004015.dat you see a name at offset 0x68 followed by the zlib data, that's the first name of the first dumped file.
the second one is at offset 0x13e
the second one is at offset 0x13e
Re: Call of Duty : MW2 fast file
ok , thx , all working fine now
well, this method is good for few-some files. But if I extracted much files in different folders - it's so hard to rename them and put into right folders
thx again

Re: Call of Duty : MW2 fast file
this is NOT a definitive method, I simply told you how I got those 2 files but there is all the rest of the FF archive to figure first
Re: Call of Duty : MW2 fast file
I understood. Do u have any ideas how to extract files more easily ?

Any clue where should be game font(s) & sub-text, if I want to translate it

Re: Call of Duty : MW2 fast file
Activision don't like modding in CODmw2 maybe this is the reason the ff's of multiplayer are crypted.

Re: Call of Duty : MW2 fast file
The files ending or starting with "_mp" will not load if they're modified on the Xbox 360, they encrypt a hash with RSA. I'm not sure if they do the same for the PC files.
Re: Call of Duty : MW2 fast file
compraring with COD4:MW, every .ff file related to MP is encrpted, add some byte to check the file between offset 00 000CH - 00 4014H , total 16,393 Bytes. After 00 4015H, it is a zlib block after 00 4014H, the same to COD4:MW .ff.Caboose wrote:The files ending or starting with "_mp" will not load if they're modified on the Xbox 360, they encrypt a hash with RSA.

I wonder who can recovering the iw4mp.exe to cr*ck the .ff
