I have just 1 main goal with my PS3: -Be able to play PS2 and PS3 games from an external hard-drive. So I guess that goes without saying that I want to be able to back-up my PS3 games onto the hard-drive if possible. What is the best way to go about this? Could I still go online with the PS3? Also, I wish to accomplish the same thing with my Wii(play gamecube/wii on external) and Xbox 360(play xbox/360 on external). Thank you .
