Hackers break PSP console 'wide open'
Hackers have successfully cracked the latest Sony PSP firmware and replaced it with an earlier version of the code containing fewer anti-piracy features.
This hack exploits a recently discovered buffer overflow exploit which allows code to be incorporated into image data. When the PSP attempts to display the picture, it writes data beyond the space reserved for the image and into memory used by executable code. The code inserted into the picture file is then run.
The software, posted on the internet, forces the PSP to run Sony's firmware 1.5 updater, replacing firmware 2.0 with the older code.
One hacker claimed the console is now "wide open".
Numerous postings on PSP-cracking websites claim the procedure works despite a system crash most of the way through the installation process. Some posters have even claimed to have re-applied firmware 2.0 successfully and downgraded to firmware 1.5 a second time, again without a hitch.
Sony released the PSP's firmware 2.0 this summer, first in Japan and later in the US. The consumer electronics giant launched the handheld games console in Europe on 1 September, and all European machines sold through official channels since then also include firmware 2.0.
