Things You'll Need
Instructions
Turn your Sony PSP on and connect it to your computer with the USB cable. Your PSP should automatically go into USB mode. If it does not, select "USB Connection" from the PSP main menu. A window will appear on your computer. Click "View files" to see the files on the PSP memory stick.
Download a PSP homebrew game. Many titles are available. Because they are independently created, they are all free .
Right-click the downloaded game archive and click "Extract" to reveal the contents of the archive. A folder will be created with the same name of the downloaded file. For example, if you download the PSPTube program, the archive will be named "PSPTube.rar." When extracted, a folder named "PSPTube" will be created along side of the archive file.
Right-click the folder that you just extracted and click "Copy." Go back into the PSP memory stick from your computer and open the "PSP" folder. Right-click the "GAME" folder and click "Paste" to transfer the copied game folder into the PSP game directory. Wait for the transfer to complete.
Press the "O" button to disconnect the PSP safely from the computer. Browse through the PSP menu and into the game section. You will see your homebrew game there. Select it to begin playing.
