PS3 hackers have shown a full PlayStation 3 game running off the console's hard drive. The hacker's game of choice was Konami's Castlevania: Lords of Shadow.
Earlier this week, Jailbreaker GeoHot posted a video showing homebrew software working on a jailbroken PS3, running Firmware 3.55.
The image released here seems to suggests that the PS3 console recognises the title as a PlayStation Network game.
Although the process is described as beyond the capabilities of 'normal' gamers it's likely that intrepid code monkeys will work tirelessly to overcome this.
Sony released Firmware 3.55 last month, calling it "a minor update that adds a security patch", however it hasn't addressed the current hack directly.
The platform holder believes that it will be able to fix the latest security breach with new network updates.
