Thats the only way to get it run (for now).
I think a real NoCD crack will take some more time
But its StarForce 3.5 which is really nasty to me, there are about >100 encrypted files for SplinterCell 3
//There are some SF3 games that arent cracked yet:
Trackmania sunrise
Codename Panzers 2
Bet on Soldier
