what is the best software to back up DC games

[EZ CD]

Well, it depends..
1.If you're planning on recopying the game you downloaded from net Ex:Sonic 2, you would use Disc Juggler..Always to Image to CD..
I do not recommand doing CD to CD..
also burn under 6x or 4x although you can burn it at 8x but I heard people complaining about it..
2.If you're planning to Rip the actual game, well
for ####ters you would a special cable..
Also I would not recommand doing it unless you really know what you're doing..
I heard bad cases where damaging the PC from something..
Although I didn't have that problem when I rip the games directly..
