Can I insert a PS2 OR a PS CD in PS3?
UPDATE: All PS3 ( 80 GB and 160 GB ) models currently being manufactured do not support PS2 or PS1 games. The last model that supported backwards compatibility was the 80 GB model number “CECHE01″ which is no longer being made. More info..
Not all PS3 consoles can play PS2 games. Currently the only Playstation 3 model that can play Playstation 2 and the original Playstation games is the 80 GB model. The 40 GB PS3 will not play PS2 games but will play some PSone games.
The older model PS3′s that are no longer being made could also play PS2 and PS1 games they are the 20 GB and the 60 GB model but those are no longer in production.
Not all PS2 games will work, if there is a certain game you are dying to play but not sure if it’s compatible with the PS3 then check out Sony’s Compatibility page, here you can enter the game title and see it that game title will work for the PS3. You can see lists of compatible games or games with known issues.
