A modder known by the name of ps3xpl0it found a way to play backed up and perhaps import PS2 games on a Playstation 3. You have to have Swap Magic discs to do this trick and make some serious modifications to your Playstation 3. By “serious modifications” I mean remove the top case, the face plate and the blu ray disc cover off. It’s an extreme situation, but it works. The video below shows Okami successfully working.
