If like me, you are curious about the copy protection mentioned in the article, here is the patent that was filed about it:<p><a href="http:&#x2F;&#x2F;www.google.com&#x2F;patents&#x2F;US4849836" rel="nofollow">http:&#x2F;&#x2F;www.google.com&#x2F;patents&#x2F;US4849836</a><p>It relies on &quot;fuzzy bits&quot; which were stored on a specific track. Reading this track repeatedly should yield different values. If the same value is found multiple times, the disk is a copy.<p>The devious aspect of this scheme is that if the program detected an illegal copy, it wouldn&#x27;t abort right away but later, in various ways (system errors, killing your entire party, etc...). The check was also performed multiple times during the game (e.g. changing levels).<p>All these reasons combined explain why it took more than a year for the first real cracks to appear.
