Instructions
Put some newspaper down on a table. Put the PS2 controller face down on the newspaper. Remove the screws from the back using the Phillips jeweler̵7;s screwdriver. Insert the flat-edged jeweler̵7;s screwdriver into the seam between the front and back shells of the PS2 controller. Wiggle the two loose. Pull the back shell off of the front shell.
Gently lift off the analog pad from on top of the analog control-stick hub. Place the analog pad down on the newspaper. Discard the PS2 controller.
Use the utility knife to remove the padded material that surrounds the analog pad. Apply the rough-finish nail polish to the flat smooth side of the analog pad. Let the nail polish dry.
Gently pull up on the analog stick of the PSP to remove it--wiggle the blade of the flat-edged screwdriver under one side of the analog stick once it has been raised a bit off the PSP to help it along.
Insert the analog pad with the flat and now rough side up into the hole that is now vacant on the PSP. You now have a large and easy-to-operate analog controller on the PSP.
