CD GAME COPY PROTECTIONS

DiscGuard

DiscGuard is quite a good protection being very effective against piracy and the piracy industry.  When first released it was the best CD-Copy Protection released, but now we have even more difficult protections to get around (one being SafeDisk 2).  DiscGuard was developed by TTR Technologies Inc. The protection works in three ways: The DiscGuard protection is applied, which encrypts .exe files, and allows a valid signature to be detected. The applications and signatures are then pre-mastered. An authorized mastering plant then creates the glass master which contains the signatures from the pre-master, and begins replication. When the DiscGuard verification software detects that the application is being run from a counterfeit copy CD, a demo version of the application or other alternate program can be run at the software developer's choice.

A major problem for legitimate owners who purchased an original game was that some CD-Rom's refused to run the original CD containing the DiscGuard protection such as Colin McRae Rally, so Codemaster's had to release a patch that removes the protection! For more information on how the DiscGuard protection was developed please visit the DiscGuard website.

Detection Of The Protection

The following files should exist on the original CD or in the games installed directory on your computer:

IOSLINK.VXD

IOSLINK.SYS

You can use one of the many protection detection tools from our Game Copy Protection Identifying Tools page to identify whether the protection is being used on your game.

Burning/Backup Solution

There are several different methods you can use to successfully burn/backup your game, as follows:

You can use CloneCD to successfully burn the game. Use ClonyXXL to scan the game, it will then tell you what protection is being used on the game (ProtectCD) and the correct settings to use in CloneCD to successfully backup the game. You can also use Alcoholer protection scanner and Alcohol 120% burning software. Use Alcoholer to scan the game, it will then tell you what protection is being used on the game (ProtectCD) and the correct settings to use in Alcohol 120% to successfully backup the game. BlindWrite can also successfully burn a game with this protection on it. You can also use Daemon Tools to emulate the game and the protection. *Remember, if you experience problems with burning the game at high speeds, (2 speed +) (both the read and write process), then burn the game at lower speeds such as 2 speed and under (both read and write process). A lot of the time burning the game at slow speeds will solve problems of the install not working, or the burner not bypassing the CD's protection.
