How can i do this?

[Tan7d]

I have 2 quetions.
1st: I want to make back up cds but i don t care about protections because i want to use cracks . But the most cracks wants full install of the games (more than 600Mb ) on hard disk because they are No CD back ups. So in the most cases is without full install the game doesn't work. I saw same isos that they have cracks only for protection(the game still need the back up cd ).Where can i find cracks like them or how can i do it my self.(Post a faq pls)
2nd: I saw a mafia back up cd that it was with protection but it wasn t 1:1 back up bacause it was have a crack dir inside.That meens that on the cd image was injected the crack .In which way this could happen?
I am a new in backing up originals cds and maybe are silly but if someone knows pls help .
