Sega Saturn

I have downloaded SIM City 2000 for sega saturn from your site and now am trying to play it.I have downloaded and installed SSf, Satourine and Saturnin. Unlike all other emulators I can seem to find the command to play the iso on any of these emulators. They are the best ones recomended and I cant find any others.How do I get this to work?

youtube has some good walkthroughs, i started there

Agreed with funguy,
Youtube have help me alot to run this emulator.SSF is the best emulator(in my opinion),
and you need virtual drive to run it if you're not going to burn the game.
