Things You'll Need
Instructions
Turn off your Sony PSP and open the memory stick slot on the side of the PSP. Press in slightly on the memory stick until you hear a slight click. The memory stick will pop out. Place it to the side.
Prepare your new memory stick by removing it from the packaging. Insert the memory stick into the PSP. You cannot use the memory stick because it is not in the PSP format.
Navigate to the "System Settings" page and select "Format Memory Stick." Select "OK" to format the memory stick and convert it to the PSP format. When the process is completed, your PSP memory capabilities will have been upgraded.
