Is it possible to make satourne loads isos?

I was fooling around with Satourne, there seems to an option to load an iso. I selected it, and it displays the iso information, but I can't seem to be able to run it. Any help would be appreciated. If I could get Satourne, or another emulator to read isos I'd save a bunch of cds and time. Thanks in advance.
I'd suggest giving Daemon Tools a shot. It's a freeware app/driver that will allow you to emulate a CD/DVD drive with disc images so that most stuff that wants a CD can just be pointed at the "virtual" drive...
