PS2 games are just too easy to copy...
If you have the original all you need to do is cd to cd copy and it should work just fine. For this you could use RecordNow Max, or DiscJuggler. Well Nero should work too. Just sue the wizard, select dvd and do a cd to cd copy.
Now you may want to select the option to create an image first to prevent possible buffer underun errors.
If you got the iso from the net and it is a full DVD iso. Just use RecordNow max with the image burning option and the default settings.
Now to play the games you should have say:
A Magic 2
A Magic 3
A Magic 3.1
A Messiah 1
A Messiah 2
I believe all these should boot just about anything. Some better than others. For example the best modchip is said to be the Messiah 2 and the second best the one I have the Magic 3.1.
Follow the boot instructions for your chip found here:
