Sony has removed PlayStation Vita compatible PSP game Everybody's Tennis from the PSN Store after reports that it had allowed pirates to crack the new handheld.
The Sixth Axis reckons that Sony previously removed MotorStorm Arctic Edge from its download portal for exactly the same reason.
Members of the PlayStation hacking community have reportedly said that both titles can be used to implement a software trick that allows users access to the system's core functionality.
From here they are able to run unlicensed code – potentially including pirated games, though that step has not yet been achieved.
Sony's PSP suffered heavily at the hands of software pirates and Sony will have implemented every measure it could conjure to try and prevent the same happening to Vita.
