In windows land, I used an app called Damon Tools to run games from an iso file I created from the original. Because I had replaced my cd-drive w/an aux-battery, I needed DT to run all games that required a disc. As an added benefit to DT, i found that most of my games loaded 2-5x as fast as a CD games and the game play was also a lot smoother.

Is there any utility I can use on Mac that will allow me to run games from an iso file?
