Copy Info @ geocities. Copy Protections This article has last been revised on: Sunday 23 January 2000 Introduction As we all know it is ILLEGAL to copy commercial CDs and sell them...It is however NOT illegal to copy them for personal backup! That's why it is useful to know that CDs can be protected in several ways. Just to make sure that you can not make any illegal copies. On this page we want to explain a bit more about the various copy-protections that are on the market and what you can do to by-pass them. I supply information on the following protections: Also some information on useful tools. If you want to use parts of this page on your page then make sure you've read our copyright information...Most of the parts written by ZiSE, DoMiN8ToR and WaxWeazle. More info can be mailed to CDFreaks. Mail to info@cdfreaks.com or e-mail me by clicking on the bottom left frame. To find out more on a simple way, visit the CDFreaks copy wizard ! ![]() An often used copy protection is the one where there is more data pressed on the then can be copied on regular 74 minutes CD-R's. So companies create CD's with 670 or 680 MB of data (and / or audio). With the wide availability of 80 minutes (700 MB) CD's this protection is far from effective nowadays. Solution: Use 80 minutes - 700 MB recordables. ![]() With this protection an illegal TOC (table of contents) has been written to the cd. When check in Windows for the size of such a CD it seems that the cd is often larger then 1 GB (1.000 MB). Of course this is not true, just because a CD cannot hold such an amount of data eg. Commandos which would appear to be 3.05Gb but is actually 467Mb from 'Properties'. Solution: Use a cd-recording program that offers the option to 'ignore illegal TOC': NERO, CDRWin, Prassi, etc.
Detect: ![]() SecuROM is one of the most known protection methods and is developed by Sony. They have a fabric in the middle of Europe where they have a machine that produces CD's with data that cannot be copied by cd-r's. On the CD's this machine produces there a few files that contain data about the structure of this not copyable data. Every time you start the game the data of the uncopyable data, and the data that is on the cd are compared, if they are not equal the game will give an error and you will not be able to play. More info can be found at: http://www.securom.com Solution: The Securom cracks
Detect: To kill SecuROM use the appropriate Generic SecuROM cracks which are available on the net... Try searching at http://astalavista.box.sk for Generic SecuROM ![]() This is also a very much used protection. It probably uses bad blocks to disable you from backing up. From the official Laser lock site: "Laser lock uses a combination of encryption software and unique laser marking on the CD surface made during the special Laser Lock mastering procedure, in order to make copying practically impossible. Every CD-ROM application has a unique locking parameter that provides a complete protection against illegal re-mastering and reproduction. Laser Lock offers excellent protection for every application as each application package is characterized by a unique encryption parameter that is specified during Laser Locking procedure."Some of this information of Laser lock maybe a little exaggerated cause of course these guys want to sell their product. Solution: You should try 'Ignore read faults' with your backup program like CDRWin, NERO or Prassi. Another option that works is copying the complete CD contents to a directory on your hard disk except for the Laser Lock dir. Load the files in this dir into a Hex editor (e.g. Hex32 or Hexworks) and save them unchanged into a dir of the same name on your hard disk. After completions burn a CD from your hard disk.
Detect: ![]() Technology that seems to be based on the Securom method. This technology encrypts the CD with a digital signature which can't be picked up by CD recorders and a multi- layered wrapper that secures the CD-ROM content. SafeDisc is currently being utilized by Eidos, TalonSoft, GT Interactive, Interplay, Microprose, Red Storm and Take Two Interactive. From the Safedisc homepage (http://www.macrovision.com/scp.html): "The SAFEDISC technology is comprised of three key features: (1) an authenticating digital signature, (2) encryption that protects the content, and (3) anti-hacking software. During pre mastering, the content is encrypted and carries with it authentication instructions. A unique SAFEDISC digital signature is subsequently added to the title during mastering. When a user plays an original disc, the authentication software reads the digital signature allowing the program to be decrypted and to play normally. This authentication process is transparent to the user. The original CD must be present in the CD-ROM drive to allow the authentication to occur. When attempting to make an unauthorized copy with a CD-R or with professional mastering equipment, the digital signature is not transferred to the copy. When an unauthorized copy is played back, the absence of the signature will prevent decryption of the program and the copy will not play.. SAFEDISC also includes anti-hacking technology that prevents the compromise of its security features. The anti-hacking technology is designed to not only deter casual copying, but also to provide strong resistance to destructive hackers and commercial pirates."More information: Cdilla SafeDisc and Macrovison SafeDisc Solution: Copy the CD with CDRWin like this: As the cd has errors first make an image on your hard disk (this can take up to a couple of hours...!). Settings: Non-RAW copy, Data read speed: 1x, Audio read speed: whatever you like (no errors on audio tracks), Ignore errors (if you use raw copy, you'd probably better choose "repair errors" to get an error free copy). After completing the image u can burn the CD. Now before you start the game from your copied CD you will have to start the Generic Safedisc Laxity crack. Note: keep the crack 'running' while you are playing the game!!! There are a few CD-Readers which are capable in making a 1:1 CD-Copy and then don't need any patch to play the game. The Teac CD-532S & Teac CD-R55S are the best drives to do this. Also other tools against SafeDisc are C.U.Dilla and unSafeDisc. These tools make it possible to create your own patches. They simply remove the protection code of the game.exe
Detect:
![]() This copy protection works like this: CDCOPS reads the CD and measures what the read speed is. This value is a number (the code) that is the CD KEY. If inserted cd has a different read speed (compared with the stored number) the cd won't work as the key is different. Using CDCOPS.DLL it is possible to regenerate the key. Info by Waxweazle [Laxity] - Seems to be part of the manual of CD Cops. "You produce a series of CDs in the normal way, protecting the main application with a utility that we supply. When you receive the shipment of CDs, which have all been produced from the same glass master and are therefore identical, you run a second utility, which measures one of the CDs and extracts an access code. This code, which is entirely public, is then included with the CD when it is sold, either as a label, enclosed in the package.Detect: When executing the program a window pops up with the words CD and COPS in the title... In the installation directory the file CDCOPS.DLL can be found. For more information about CD-Cops read here and here for more information on possible cracks. DiscGuard (not widely used, i.e. I haven't experienced it either) DiscGuard™ is an anti-piracy technology for optical media that works by putting a "signature" onto a glass master during mastering, using a specially enhanced mastering machine, or onto a CD-R via DG-Author™, a forthcoming product (Q3 '99) consisting of a specially enhanced CD-R recorder with proprietary software. Addressing both problems of illicit mass-reproduction of software or other electronic content (counterfeiting) and copying by a casual user using the low-cost CD recorders available on the market today (disc burning), the Company's innovative solution for CD replication protection is integrated into the laser optics system of CD mastering machines. This technology enables the detection of unauthorized reproduction of the CD itself, without reference or change to the data contained on it. The unique DiscGuard™ signature is not reproducible by pressed disc counterfeiting nor by CD-R burning. Thus, a pirate who attempts to replicate a DiscGuard™ disc will be able to only copy its content but not the embedded signature. When the DiscGuard™ verification software detects that the application is being run from a unauthorized copy CD, a demo version of the application or other alternate program can be run at the software developer's choice. Solution: Cracks ![]() BlindRead (official website is Blindread.com) is a really nice program if you want to create backup copies. It allows you to copy CDs that use the copy-protection of 'unreadable files'. Early versions of the program were in French but was easy to understand, there is now proper support for the English language. Another useful program is DiscJuggler by Padus Duplicator is a burning program that supports only a few types of burners but if it works on your burner you will be able to burn almost every game !
