I learned something new today that I didn;t know about earlier. While I know that there was PS2 backwards compatibility for certain versions of PS3, I had no idea that all version of the consoles can still play PS1 games. What I would like to know if what are cons of playing PS1 games on PS3? I know the system does have Memory cards or not every game supports Dualshock. I also want to know if I better off just using the PSN games where I can just upload my PS1 saves from my memory cards?
