p2p news / p2pnet: Jake D at PSPupdates.qj.net reports, "Break out your calendars folks, because this may be a day that you want to mark as a pivotal day in the history of PSP homebrew. A developer known as hitchhikr of "hitchhikr SoftWorks" and coder companion Neural have come out with a Proof of Concept of a 2.50/2.60 Firmware Exploit! "

Today is the biggest day in 2006 for PSP homebrew. Beforehand, only firmwares 1.00 and 1.50 could run full kernal access homebrew, allowing for any unsigned code to be used.

Now, though, the discovery of an overflow bug in the added security check for PSP Firmware versions 2.50 and 2.60 has meant kernal memory dumps can be made to the Memory Stick Duo.

This doesn’t sound like big news, but it is. It’s VERY big!

Previously, 2.xx users had only one option to use homebrew, which was the Grand Theft Auto: Liberty City Stories savegame exploit, using Fanjita’s eLoader. But this only allowed for limited use homebrew, and no flash memory access.

Sony has tried many times to stop its PSP users from running homebrew, such as the 2.01 update, where the only actual change the PSP system seemed to have been the fix for the Picture Viewer buffer overflow.

The 2.70 update too fixed the GTA savegame exploit.

QJ.net does, though, say, "But don’t start upgrading those PSP’s yet until a viable means of implementation is released! Also, this breakthrough does not open up the possibility of a downgrader due to the protection in the IPL in 2.50+ firmware."

It’s been confirmed, and it does work, but for the moment, there’s no actual implementation, although Fanjita says he’s, "already working with hitchhikr on incorporating this new exploit into an easily executable means via eLoader.

"After a brief chat with Fanjita, he’s told us that you can expect some generic application for developers to hopefully be released in the next 24 hours."

The Proof of Concept work is avaliable, but isn’t aimed at the casual user.
