Minimum:

• If games take you to Steam page or ask you about CD key/Keygen when start game, that mean you still not crack it. Open .ISO files, you will see a folder (Its name may be: CODEX, CRACK, PROPHET, SKIDROW,… You don’t care it), you copy all files in that folder and paste into game’s folder, then start game, have fun ?

Recommended:

• If you don’t get .ISO or .CUE or .MDS, that mean only need extract and play (The cracked files inclu by itself). Maybe your anti virus deleted cracked files when extracting. Now, you turn off your anti virus and firewall, then extract again.
