If you want to make an image of your game on your hard disk, you can use Limewire or WInMx to go and get IsoBuster. It will open the image back on your hard disk (no on a CD) and then in your game .ini file you can direct startup to the folder you created instead of having it directed to your cdrom.
Too bad if you directly copy a game or program from one HDD to another, the registry settings are not sent over, and it screws up eh? Besides, you are all HORRIBLE PEOPLE! Quit hacking games! Game designers don't make enough money as is, and when you steal a game, you take from the company which in turn pays their employees less money, which in turn makes employees angry and sad, which makes company make a worse game next time around!! BAD PEOPLE YOU ALL ARE!! SHAME!!
