Well, probably the best program for that (since you have a Phillips) is CDRWIN. You might wanna double check however, if Clone CD supports your cd writer.
Nero also allows you to make copies of psx games, but remember, you need a mod chip to play these.
The good thing about Clone CD is that it will even copy the games that are protected. Ever since I got Clone CD, I don't use any other program.
These programs are pretty much straight forward, and if you have any problems, you can find tutorials all over the net by doing a simple search.
