100% perfect cd-copy of games with safedisc v2 ????

[Shang Tsung]

I've noticed that I can copy every CD I try with my old Smart&Friendly 4x2x24 CD-RW, using Nero version 5.5, but some of the new games will refuse to run and require a patched EXE to run from the burnt CD. Therefore it isn't a 1:1 copy.

Is it possible to make 1:1 copies? What does it depend on? The hardware or the software?

I see many people recommend CloneCD. In what aspects is it better than Nero?
