copying psx games with an iMac

[romal]

I have the latest imac and I am tryimg to copy PSX games. I use to have an old Performa 6300 using Astarte 1.0 or 2.0 to copy to my hard drive, then Toast to burn the cd. The Astarte programs do not work on the iMac. I have Toast Titanium, but this does not seem to want to work. All the files appear to be there but when I attempt to play the copy it wont get past the intro screen.
Any help would be appreciated
