The peak of the StarForce 3 protection system is the encryption of all data on the DVD (like in Splinter Cell: Chaos Theory).
doing that makes sure that an .exe crack is not possible.
So this is the good thing from the manufacturers p.o.v.
The bad thing is that in a lot of situations, SF3 will not work even if one has the original version of the game.
The good thing: it can be tricked into working with fake images and/or by disconnecting the real drives.
Requirement for King Kong is just Daemon Tools 4.0 (I'm saying this from a educational p.o.v.) and a mdf/mds image of the game.
