Two PSP titles are back on sale after Sony took action to combat a possible PS Vita security breach. Last month Sony removed Motorstorm: Arctic Edge and Everybody's Tennis from the PlayStation Store after hacker Wololo found that they contained a loophole to allow unsigned homebrew code to run through the Vita's PSP emulator. We can confirm that both titles are back online in the European Vita store and selling for £6.99 each, in line with recent price drops on several other PSP titles. While the loophole has been closed for now, Sony might not be able to rest for too long — Wololo applauds the company for restoring the games, but warns that he has an exploit for another title ready and waiting in the wings.
