No problem. I will get round to explaining the way it works in the future. I hope you can tell those Painkiller fans that this support is upcoming!

I'm working on it, to implement it in MultiEx Commander. Making progress! See the screenshot!

I haven't used any of the dll's or exe of the program. Just a hex editor, a piece of paper and thinking binary.

Good news for those interested : I cracked the Painkiller *.PAK filename encryption code. I wrote a little PAKAnalyzer to test my theory and it worked. It shows the contents of a given *.PAK file. Here's an example of a text file that it creates: XeNTaX' PAYNKILLAR *.PAK Analyz0r - 2004 - Mike Zuurm...

That I knew already.

The problem is finding the start "XOR" number for each filename string.
And that's what I am trying to figure out.

Right, well, I figured it out almost completely. The PAK format now uses ZLib instead of PKZip compression. I have only to figure out how it encrypts the names of the resources and we're done.

How big is that file in bytes you are talking about?

Yes, I will add the option to import/replace files in the archives with the release of a new MultiEx Commander that is due somewhere next month probably. I tested it in my release candidate, and it works. Just hold your breath until then.

In the first demo,.pak was altered pkzip file,another curious guy brought the way to get it back but all has changed,at least in the retail version,the pak version seem xored. OMG Why did you not say this before? If you already knew that the demo version was an altered zip file, I needn't have look...

Hey what is "buster" ? Im open mexbinder.exe right?, create a new mrf right, dpk starmageddon. save this, and run the program multiex sel open dpk sel dpk file and i see error? anyway thanks for help!!!!!!!!!! Buster = Bozo, And, I advise you NOT to use mexbinder.exe, but to use Multiex Commander. ...

Actually no, the resources in there are packed using unzip32.dll or some other standard PKZip tool, but the file uses it's own format to store the variables PKZip would need. . I'm working on a way to either convert/reconvert the *.PAK <> PKZip (so you can open them using WinZip) or a MultiEx Comman...

Well, send me tool (not plugin) tool for Extraction and Packing files in DPK Format Thank you very math! Captain is right, that's not going to work, buster. :evil: For the DEFINITE answer I downloaded the Project Earth demo which has one HUGE *.DPK file, I downloaded the above mentioned scripts and...

I have the game and also interested to unpack those files. not for the contents but to learn. maybe can you (Mr.Mouse) post a small tutorial on how you reverse the pack process? i'm sure others people here would be interested to learn instead to use like common users.. Hope nothing unpleasant in my...

OKay, that was an easy one. This I got out of it (as just an example) http://www.xentax.com/taoc/pics/S_Logo.png Use the "Use custom BMS on..." option in MultiEx Commander to open *.DPK files. Get this BMS script to run it and extract those that are Zlib compressed as uncompressed files: http://www....

Well, email them then ! You can get my emailadress from the site!
