Clony XXL ; Alcoholer; and Alcohol 120% are all you need for backing up games the first two are free but you have to pay for Alcohol 120%. This has worked for me to back up all of the games that i have.
1. start clony xxl scan the cd
2. load alcoholer, it will create a profile for the game you are trying to backup
3. start alcohol 120% use the profile that alcoholer created to make an image. this way it will only take a couple minutes to make the image instead of hours like with clonecd.
This is just the way i do it. there are probably other ways but this is the way that i have found to work best.
