The first mod chip has been released a couple of days for the Playstation 3 (PS3). It allows installation of any firmware revision you prefer for your best gaming experience, means you can up- and downgrade to whatever firmware you like (see video below). And no: it does not allow playing backups of your games. Even if you could afford a blu ray burner you cannot backup PS3 games currently.
The interesting point is: this chip is platform independent and can also be installed into Nintendo’s Wii or Microsoft’s XBOX 360. Since we don’t know for sure about the legal situation for such a mod chip in our beloved Germanistan, we will not include any links in this article. You know how to find, otherwise you would not be here ;-) Thanks for your understanding.
