I have recently bought The Sims 3 and after installing it, when I came to run the program it asked for the installations DVD (naturally). I created a read-only disk image using Disk Utility but it still asked me for the installation DVD when I mounted the disk image (understandably!) I can't download the game from direct2drive because I don't live in the US, and I don't want to be carrying the superdrive around with me, I heard something about a virtual drive, but isn't that what Disk Utility is used for? Has anyone managed to do this? Thanks, S.
