PlayStation 3 (PS3) was designed to play high-definition games as well as the entire library of original PS games. Depending on the PS3 model you have, you can also use the console to play games released for PS2. PS3 consoles that are backward compatible with PS2 games must be configured to save PS2 games on the console's virtual memory card while also ensuring that the game runs optimally on the console.
Check to make sure that your PS3 is backward compatible with PS2 games. Models released with a 20GB or 60GB hard drive are compatible, as are 80GB models with the model number CECHE01. Slim model PS3s are not compatible with PS2 games.
Power on the PS3 console. Navigate on the cross media bar to “Game,” and scroll up to highlight “Memory Card Utility (PS/PS2).” Press “X.”
Select “Create New Internal Memory Card,” and press “X.” Highlight “Internal Memory Card (PS2),” and press “X.” The memory card will take up to 8MB of space on your PS3. Name the card, and select “OK.”
Return to the cross media bar and scroll to the “Settings” heading. Scroll down to “Game Settings,” and press “X.”
Select “PS/PS2 Upscaler,” and set it to “Normal” if you're playing on a widescreen HD television or to “Full Screen” if you're playing on a full-screen HD television.
Select “PS/PS2 Smoothing,” and set it to “On.” This will smooth out textures present in PS2 games, allowing for slightly better graphics to be displayed.
Insert a PS2 game disc into the console. Start the game from the “Game” section of the cross media bar. Press “X” to begin the PS2 game on the configured PS3.
