The only real way of knowing if you can copy games is by trying.

Everyone has started where you are know, you will also make several coasters in the process but the main thing is trial and error.

Get hold of a non-protected Ps-1 game which you fancy and follow the tutorial for CDRwin on my site and if you follow it step by step you should make a working copy.

Don't be 2 disheartened if it doesn't work just post back here and tell us why and someone here will help you, but try copying first and see how it goes.
