Just got my DC and...

I know that many of you regulars to this forum get this question all the time. So I would like to begin with an apology for my incompitance.
I have a Creative 8x4x32 and I use NERO to make back-ups of all my PSX games, I have been told that I can do the same thing with DC games. Is this true and if so, how? I am also looking for a Gameshark code for: TombRaider:Chronicles if any of you could plz help me, or lead me in the right direction. I would apreciate it very much if you would just email me a responce.

Thanx in advance
