Instructions
Turn on the PS3 console along with your TV.
Insert the CD of the game you would like to load with Multiman into the PS3's disc slot. You can also plug the USB stick that contains a backup copy of the game you want to load into one of the PS3's USB slots. If the game you want to load is already stored on your PS3's internal hard drive, skip this step.
Use the PS3 controller to go to the "Game" icon in the PS3's XMB menu. Highlight "Multiman." Press the "X" button to open Multiman. Multiman will scan for all of the available games stored on the PS3's internal hard disc drive. It will also scan for games that have been loaded in the PS3's CD disc slot, in addition to games stored on a USB external drive that has been plugged into the PS3 console.
Highlight the game you want to play from the list of available games. Press the "X" button on the controller to load the game.
Select "Yes" when prompted to start the game without going back to the XMB menu.
