You do not need to use unsafedisc, and using it would be illegal by the terms of the EULA of the game, because it removes the safedisc protection.
Our aim here is to copy protection(or emulate it), especially with your burner which is a 2 sheep burner.
1) You can use the Safedisc profile with no AWS if you are using CCD.
2) You can also make an image with CCD and check option to create a ".cue" file and burn with fireburner.
3) You can even use DiscJuggler to make an image and burn it as well all with DJ.
4) You can make a copy with Alcohol.
If your burner is the only optical drive you own, you will need to hide atip info from the backup, for all you know maybe your current backup doesnt run because of that.
A) CCD installs a Tray from which you can check "Hide CDR Media"
B) Alcohol also has an option for this.
