Things You'll Need
Instructions
Locate your PS3 model number using the PS3 system software. Turn the system on, let it fully boot up and highlight the "Settings" tab. Select "System Settings" and then "System Name." Write down the model number that is shown on your screen.
Use the model number to determine whether your PS3 supports backward compatibility with PS2 games. Websites such as the Playstation Support Site or Third World Geek have charts sorted by model number that indicate backward compatibility status. If your PS3 does not support backward compatibility, you will not be able to play PS2 games on it.
Download and install the official PlayStation 2 System Data add-on. Turn on your PlayStation 3 and allow the system to fully boot up. Using the controller, navigate to the PlayStation Store tab and open the PlayStation Store. Select "Add-Ons" and then choose "Disc-Based Games." Scroll down to the bottom of the menu and select "PS2 System Data." Confirm the download when prompted. When the download completes, press the X button to install the PS2 System Data add-on.
