Hackers have been able to crack the PlayStation Vita's latest firmware, allowing them to run homebrew via an exploit found in downloadable PSP games.
Sony recently returned two pulled PSP games to the PlayStation Store after releasing firmware 1.67 for the PlayStation Vita. The firmware was thought to patch the exploits discovered within these games, but it seems that hackers found another game to exploit. Hackers have posted videos of the PlayStation Vita running the original Doom, but aren't revealing which game they are exploiting, to keep Sony in the dark and prevent them from taking action.
The PSP was plagued by piracy, reducing profits from sales and making developers and publishers uneasy about creating software for the console. Sony has done much to prevent piracy on the PlayStation Vita, but it appears that the Vita's ability to play PSP games may open doors Sony would rather keep closed.
Let's pray that this doesn't get out of hand and lead to an early grave for the PlayStation Vita. Which is actually a great little device.
