Sony is seemingly fighting an uphill battle against Vita hackers as new firmware fails to prevent a new homebrew hack from emerging soon after Sony's scrambling recovery.
The platform holder moved quickly to thwart thefirst emerging Vita hacks when it removed from the PS Store multiple PSP games used to assist the hacks, and put its engineers to work on a new more secure firmware.That firmware, version 1.67, has been deployed and the removed PSP games - MotorStorm Arctic Edge and Hot Shots Tennis - have reappeared patched to prevent further tomfoolery. But, it seems, its rapid effort were in vain.
Hackers claim to have found another PSP game that opens the door to homebrew on Vita including, unfortunately for Sony, on the new firmware. Videos of the original Doom for PC running on a Vita with the latest firmware installed have already emerged.
What PSP game is it? The hackers are staying tight-lipped for now to slow down any potential response from Sony. But the to-and-fro battle with hackers has certainly begun.
