Copy protection
There are several CD copy protection solutions, including SafeDisc, StarForce, and SecuRom. Most of these solutions work by duplicating errors. When it's created, a copy-protected data disc is burned with unique errors or physical flaws. Under normal usage these errors are ignored. But when you try to copy the disc, the CD-burning software tries to correct these errors. After receiving the first few errors, the burning software decides the disc is damaged and aborts the burn.
Alcohol 120% can duplicate these errors on new CD-Rs using a different backup method for each type of copy protection. Backing up your games is a two-step process:
You must identify the type of copy protection used on your games. But how?
Use the internet.
Fire up Alcohol 120% and select Copy Wizard.
Under Datatype choose the copy protection of your game.
