Instructions
Insert your Memory Stick Pro Duo into the memory stick slot on the side of your PSP. Turn the PSP system on.
Plug your PSP into one of the USB ports on your computer with the PSP USB connection cable.
Navigate to the "Settings" section of your PSP's Cross Media Bar. Select "USB Mode" from the list of options to place your PSP into USB mode.
Double-click on your PSP in the "My Computer" section of your computer to open the PSP's root directory. Open the folder titled "PSP."
Create a folder inside the "PSP" folder and name it "THEME." Be sure to use all capital letters.
Open the Web browser on your computer and navigate to a website that offers PSP themes for download. PSP-Themes and PSP Theme Central are two websites that provide this service. Locate a theme that you like and click the download link to begin the downloading process. Allow several seconds for this process to finish.
Unzip the files you downloaded in Step 6 using an expander program like WinZip or WinRar. Locate the file with a .ptf extension. For example, psptheme.ptf.
Drag the .ptf into the "THEME" folder you created in Step 5. Right-click on the PSP icon on your computer and select the "Eject" option to eject your PSP from your computer.
Navigate to the "Settings" section of your PSP's Cross Media Bar. Scroll down and select the "Themes" option. Select your theme from the menu that appears to set that theme on your PSP.
