Recently, Sony released a Playstation Portable firmware update 5.51. And now, Miche2245, a German developer discovered a Game Save Vulnerability in the PSP firmware 5.50.

This firmware currently works for the Japanese version of Monster Hunter Freedom 2 and the English version of Need For Speed: Underground Work. But I’m sure in the coming days, there’ll be more games compatible with this firmware. The ability to save the game is widely needed especially for gamers who always forget to pack some extra power in their batteries.

Meanwhile, the exploit you will find in the package is for the Monster Hunter Freedom 2. After executing using the saved game, you can now make use of the ChickHen, a homebrew enabler, under the PSP firmware 5.50.

There’s a more detailed instructions on the readme file included in the download, so I suggest you take a good long look on it before you install this firmware.
