The Sony Playstation Portable, or PSP, is a mobile gaming system. Rather than using internal memory for the storage of saved game files, music, games or any other information, it uses a separate memory card known as the Memory Stick Duo, which is a standard format among many Sony electronic devices. The PSP ships with a 1 GB Memory Stick Duo, which is adequate for many people, but others find that they need more space. If you find that you need to upgrade to a higher capacity, the process to swap them out is very simple.
Instructions
1. Locate the door on the side of your PSP that protects the Memory Stick Duo slot. It will be on the left side of the PSP as you face it from the front.
2. Open the Memory Stick Duo cover door using your fingernail or a thin, flat tool.
3. Check to make sure there is not already a Memory Stick Duo inserted in your PSP. If there is already one there, gently push it inward until it clicks, then release. It should slide out easily, freeing the space for your new one.
4. Slide the Memory Stick Duo into the slot in the side of the PSP. The label should be facing the same direction as the LCD screen, and the notched corner of the Memory Stick Duo should be up. Put in until you hear a click, then release.
5. Replace the door covering the Memory Stick Duo slot. It is now installed, but still needs to be formatted before it can be used.
6. Turn the PSP power on.
7. Scroll to the "Settings" option on the PSP menu, then scroll down to "System Settings."
8. Press the "X" button on the PSP to select the option.
9. Scroll down to "Format Memory Stick."
10. Press the "X" button on the PSP.
11. Select "Yes" to format the Memory Stick Duo and prepare it for use.
