it it possible Sony can upgrade ps3 systems that cannot play ps2 software, to playing ps2 software?
Even if it were possible, they wouldn't do it because they are now selling digital PS2 versions on PSN (and remastered versions) that will work on all PS3 models.
How many times does this get asked per week? Per day even?
Only the Shadow knows...HAHAHAHAHAHA
There is another route....... but its illegal.-Minds are like Parachutes. They work best when open. -There's no limit to what brainwashed people can rationalize
You could just do it for personal use and stay off the PlayStation Network. I'd be totally okay with that, and I don't think anybody would care enough (i.e. waste of time and money) to drag you into court for something they may not even win.
But if PlayStation Network is a useful feature to have, then just buy a cheap PS2.
