Can PlayStation 3 Play PlayStation 1 games?
I know this is an old topic but I feel I should clarify. Every model of PS3 can play PS1 games: both disc and digital version. Before a patch that came out a few years ago, it was only the 60GB fat models that had an kind of backwards compatibility. Then not long after PS1 classics were introduced on the PlayStation Store, they released a firmware update that allowed for the feature to be used on all models. However, the original fat 60GB is still the only one that can play disc-based PS2 games. All other models can only play PS2 games in their digital format (whichever ones are available on PSN anyway).
