Extract some models and textures?

[1qwerty]

I extracted a PSP.DAT file out of KZ:Liberation UMD, which is 500Mb so all data is obviously there.

How can I rip off some files from there? There's plenty of filenames at beginning when viewing it with hex editor.

I really want that helghast soldier model. He looks so cool.


Edit: Nothing found with google, dogpile and other search engines.

So maybe if I'd write a program to read that file would be the only solution?
