1. what is/means NTSC & PAL format?
ANSWER: NTSC is the 525 line/60Hz TV standard used in USA/Canada/Japan (plus a couple of others); PAL is the 625 line/50Hz TV standard used elsewhere.

2. what is a patch? what is it for?
ANSWER: If the patch is for NTSC to PAL, it means that the indicator within a specific game location that the game is for NTSC is changed to PAL. The effect of playing an NTSC game with a PAL TV and without a patch or a hardware NTSC to PAL convertor is usually that the picture is greyscale or rolls.

ANSWER: Copies need a modchip due to the prootection mechanisms deployed by Sony.

4. to many questions??? Hope not.

I already did a backup of one game (Atlantis); I used Nero 5.5.4.0 and played in my computer with "Virtual Game Station".
My cd-writer is a TDK 16/10/40 Velocd.
COMMENT: Nero is no good if you have to patch the game in any way. You'd need to use CDR-WIN
