Of course I understood situation that it is not legal to public decrypted game files (and copied from disc encrypted too).
So I am not insist, but anyway, if somebody has PS3 Development Kit and GTA IV, please, spend 5 minutes - load disk in "encryption mode" and send me this file in PM (hope that this will be allowed).
It will be very helpful. Next research is more understandable. I already can have acess to .self file disassembly. Encrypted files are just a "roadblock" for me.
Thanks in advance.
