Sony has been working hard to stay in front of pirates looking to exploit the Vita. To that end two PSP games have been removed from the Vita Playstation Network Store since it was discovered they could be exploited to run homebrew software.
As reported by The Sixth Axis, Sony has removed Everybody’s Tennis from the Playstation Network since the game has, as homebrew site wololo.net puts it, “a vulnerability that could lead to the execution of external code by some malicious users.” (This is the Japanese version of the game Hot Shots Tennis, which isn’t available in the U.S. Playstation Network Store.)
Sony yanked the game just weeks after it removed MotorStorm Arctic Edge from the store after wololo.net released Vita Half Byte Loader files that took advantage of exploits within that game to run a “limited PSP homebrew experience” on Vita.
Piracy was a significant problem on the Playstation Portable. For example, Square-Enix’s peculiar brawler Dissidia: Final Fantasy was illegally downloaded more than 5.2 million times between its 2009 release and the middle of 2010 according to the Computer Entertainment Supplier’s Association. The CESA estimated that Square lost around $335 million in sales due to piracy.
Bootlegging losses are only part of Sony’s broader problem with hackers, its gaming machines, and the Playstation Network. The company had to shut down the Playstation network for over a month in 2011 after hackers stole user information for millions of PSN accounts.
