Instructions
Turn on your Sony PSP and wait for it to boot up. Your PSP has a USB port at the top of it. Locate it and plug your USB cable into it. Plug the other end into the USB port on your computer.
Open your PSP memory stick on your computer and you will see many folders inside of it. Locate the "PSP" folder and open it.
Open the "Game" folder inside of the "PSP" folder. This is where your emulators will go. Download one or more of the emulators from the resource section of this guide.
Copy and paste the emulators into the "Game" folder and wait as they transfer over. When the process is complete, press the "O" button on your PSP to eject it from the computer. Unplug your USB cable.
Navigate through your PSP menu until you get to the game section. Select the emulator from the list of installed games.
