Instructions
Turn on your Sony PlayStation 3 and select the "Settings" menu.
Select "Remote Play Settings" and choose "Register Device." Your Sony PSP will appear as a device in this window. Select it using your controller to join or "pair" your PSP and PS3.
Return to the "Remote Play Settings" window and make sure that "Remote Start" is set to "On." If it isn't, turn it on. When this is done, turn off your PlayStation 3 using its main menu command.
Turn on your Sony PSP and choose the "Network" menu option.
Choose "Remote Play," followed by "Connect Via Internet." You will be asked to pick which wireless network connection you want to use when activating this feature. Select the listing for the same wireless network that your PlayStation 3 is connected to. When prompted, enter your PlayStation Network user identification name and password. Your Sony PSP and PlayStation 3 are now connected via "Remote Play." The PSP can now read from the PS3's hard drive.
