Arkus, ALL PS3s play PS1 games. ALL of them.
However, most people are convinced that the newer ones don’t play PS2 games. Which isn’t true. For some reason, Sony can’t stay consistent on whether they want them to or not. Mine does. I’ve had it a year, it’s an 80 gig slim model, and DOES play PS2 games.
I didn’t specifically request it from Gamestop by searching the relevant serial numbers. I bought it off the shelf at Wal-Mart and it does what I want. I don’t even own a PS2 anymore.
