From what I see it took at minimal, some effort to extract and make No-CD programs. If i'm right, everytime the game got updated you'd need different No-CD crack too so I guess some of the crack makers just don't have time and effort to keep up with the game developers.

Bout the questions not answered: just my opinion - but I can see lately its been a large number of 'authentic' newbies or some people just fakes it as them in hope of getting help.
