Help

[Price]

I have just got a HP cd-rewriter and would like to make backups of all my games. I have tried to copy Sim City 3000 and other games but had no luck. I have no idea about cracks, cd protection and general copying. I would be grateful if you would be able to give me some general steps on how to copy PC and PS games.
Thanks for any help.
PS. i just downloaded Clone CD but dont know what to do with that.
