Hi,
one of the best programs for backing up software and games is "CloneCD 5" from SlySoft.
You can find the latest version (5.2.6.1) here:
http://www.slysoft.com/
Download and install this program, then create an IMAGE of the disc, using the 1. menu-icon (from left)! After that burn the IMAGE of the CD on a CD-R using the 2. menu-icon of the program (from left).
If you have any questions, send me a PM!
