(adsbygoogle = window.adsbygoogle || []).push({}); This is Cod4, but this works with MW2, Cod5 too! But you need HDD Decryption with FW under 3.30

1st step:
IW added an additional file header to the ff-files (12-bytes: 49 57 66 66 75 31 30 30 05 00 00 00) and you need to remove it first before you can decompress the file.

2nd step:

After removing the header, your file should begin with 78, the header for Zlib with max./best compression. Store the file (don’t overwrite your sourcefiles, always create backupfiles first) in the folder where the ff_iw.exe is located. Open or create the decompress.bat or anything like that, use the command “ff_iw –d NAME_OF_THE_FF-SOURCEFILE NAME_OF_THE_NEW_GENERATED_FILE” in it and run the bat-file.

3rd step:
Now you will find a decompressed file in your folder. You can open this file with the Hex-Editor and do with it whatever you want. You can rip content, edit content or just check the files included for an overview.

4th step:
When you’ve edited the content and want to test something you only need to compress the file again. Use or generate a compress.bat or anything like that, use the command “ff_iw –k NAME_OF_THE_EDITED_SOURCEFILE NAME_OF_THE_NEW_GENERATED_FF-FILE 9” in it and run the bat-file. Don't forget the value 9 for best compression!

Hints:

In front of the files you will find the length of the file. 4 byte in little endian (reverse order). It often makes ripping of the files easier when you use the length.

Not been working on them for a few days but offzip is much better. And the 1.11 patch has 22 zlib blocks inside. All decompressible. Gonna try a rank mod later when I can be bothered

So all the times people have been trying to open PKG's with Linux could have just used offzip?
Also i was wondering could you place a X360 fast file into a PKG, or are the headers different?

Pkg method is a massive fail. Waisting time with it. It's signed

How else is it possible to get challenge lobbys then?
It cant be through Mpdata or split screen as they have modified all CoD's to get challenges.
There must be another method like tricking the ps3 to download game settings from a pc

ROLL TIDE!!!
If it was MPDATA then we would have had it working already cause the prestige ahck is done with that file.

I personally dont think it is the MPDATA cause no way to make it go online.
