Things You'll Need
Instructions
Turn off your PSP and unplug the power cable if it is plugged in. Remove the normal battery and Memory Stick from the PSP and place them aside.
Put your Magic Memory Stick in the PSP first. Put your Pandora battery in the PSP second. Your PSP will turn on automatically, and a blank screen will appear. After a few seconds, white lettering will appear.
Press the "X" button to proceed with installing custom firmware. Press the "X" button again to verify your selection and wait as the new firmware is installed onto the PSP.
Press the "X" button to power down the PSP when the install is complete and remove the battery and Memory Stick. Reinsert your normal battery and memory stick and turn your PSP back on, sliding the power button upward. Your PSP now can play games directly from the Memory Stick.
