This article is from the CD-Recordable FAQ, by Andy McFadden (email@example.com) with numerous contributions by others.
Requests for information on how to copy recent games occasionally sprout
up on the newsgroups. Generally the publisher has employed some form
of copy protection that prevents the disc from being duplicated easily.
If you try to play the game from the duplicate, the game will usually act
as if the CD-ROM weren't present and tell you to insert it.
Most publishers are well aware that there is no such thing as an
unbreakable copy protection scheme. It is possible though to implement
a method effective enough to slow the tide. If you don't believe that,
start counting posts the next time a popular game with decent protection
is released. See section (2-4) for some technical details, and section
(3-42) for a discussion of why you can't write a general-purpose disc
copier that works for everything.
If you're looking for information, the most appropriate places to search
are "warez" newsgroups and web sites. Searching the net for tips is a good
way to get started. Be forewarned that any "cracks" you download may very
well also be viruses, and that if you give away or accept a copy of the
disc from someone else you are probably breaking the law.
Aiding and abetting the illegal distribution of copyrighted works is
not part of this document's charter. There are plenty of newsgroups
and web sites devoted to the subject, so please don't waste bandwidth
in "legitimate" forums asking for cracks. A search engine such as
http://www.google.com/ will turn up many sites with such information.
Incidentally, the government of the USA and several other countries are
starting to crack down on illegal trading of software and digital video.

release on a December 11 2001 crackdown.
