The user interface is in German but it should work without knowing the language.

nice man.
nice
what forum was it btw?

[Slaii]

Thanks, it works....

It's in German, though.

I made the tool and NicoDE gave me his specs since I was missing some stuff (actually just the date/time fields )

[Slaii]

And any tool for packing back the files?

I want to make a mod and I need to pack files back (or I should leave them in directory?)

[john_doe]

Yes, NicoDE made two command line tools, one for extracting and one for creating new archives.
You can get his tool from here: http://forum.worldofplayers.de/forum/sh ... ost2487521
You need to be registered, though.

The .pak it's a normal zlib no?

[john_doe]

Yes, it uses the normal zlib library.

Great, thanks............
