Everything Can be copied
 

With a little time and patients (and the right equipment) you can backup anything. I have 2 small children with their own computer and as you know they really don't take care of CD's ($40 a pop) so I make a backup of everthing, and i haven't found a single game uncopiable , so pay close attention to your settings & BURN BABY BURN!!!!!!!!!!!

Correction: Everything can be copied with the right equipment
 

Try to copy a CD protected by StarForce or Tagès... and you have a new experience: They can't be copied (with actual burners).

BTW: Example for Tagès is MotoRacer 3.

Though it is possible to back it up (though not a perfect copy) by using a crack.

can u help me please? I can't make a backup of my games, they are mainly flying simulators, u know F-18, Mig-29...

looking for help, but cannot find any. I'm trying to make a backup but no success at the moment, could you help me please?

Download Clony XXL which will tell you the protection being used and the correct settings to use in Clone CD (hardware dependent). Once you've tried that, if you still have problems, then you should ask for help, not before (as you don't seemed to have searched the forum well enough). And also what burner you have will be helpful if you have a problem.
