Antstream recently posted a Q&A video in response to peoples’ concerns following the Xbox announcement and ensuing public awareness, including a section about the low number of PS1 games, something brought up by a grumpy article on Gizmodo (and, later, by Kotaku’s own David Smith).

You’re probably talking about the DOS version. The version on Antstream is the Amiga CD32 version, and since pirating CD-based games was prohibitively difficult back then, they typically didn’t have copy protection.
