Theme Installation

Copy the .ptf files into your PSP's theme directory X:/PSP/THEME/.

NOTE: Some of the files are in .7z / .zip format. Those have extra wallpapers inside.
Extract them using any extraction tool (e.g. 7-Zip, WinRAR, WinZip...) of your choice.
Copy the images inside the Alternative Wallpapers folder into X:/PSP/PHOTO/ or X:/PICTURE/.
