Things You'll Need
Instructions
Changing the Color
Turn on the console and press the "Home" button to return to the Home screen.
Scroll left to the "Settings" menu and choose "Theme Settings."
Highlight "Color" and press "X."
Scroll through the available colors, until you find the one you like the most, and press "X" to select it when ready. By default, the option is set to "By Month" which changes the colors on your Home screen automatically each month.
Applying a Theme
Download a custom theme from either the "Playstation Store" or the internet. You should be able to find themes around the internet, in places like the Sony website (see Resources). If you are downloading the themes to your computer, you'll need to put them on the Playstation memory card through USB connection: plug a compatible USB cable into the computer and PSP, then select "USB Connection" under the "Settings" menu.
Press "Home" to return to the Home screen, and scroll right to "Settings."
Select "Theme Settings" and scroll through the available themes. The themes you have downloaded and put on the Memory Stick Duo will show up next to a memory stick icon.
Press X to confirm the selection. The system will apply the theme, and the screen may go blank for a few seconds.
