how do you play games when you downloaded from a website and there rar files and you rar them and then what do you do after that in order to play it
You'll need a HD emulator like deamon tools or alcohol 120. Extract the files, then mount the image to the emulated drive you create with daemon tools or alcohol. Usually, the newer games pick up on the fact that you are running emulator software, and alot of the times the program YASU helps with hiding that drive. Get that too. As soon as isohunt.com is back online, check out their forums. There are detailed instructions on this subject.
