Can I copy a copy?

if I make a bake up using alchohol, blindwrite or gamesxcopy, and want to make a copy from that copy can I just copy disc in Nero or do I have to use emulation software again. Does the copy software remove the protection or does it copy it also with the game.

The Copy Protection is copied as well so to copy the copy you would need to use the same software you used originally. But if the copy is not perfect then the copy of that copy will be worse.
