Hacking PSP works with PS Controller

(via AcidMods)

It basically hacking the PSP by installing 25-pin SMT connector, modified from the old Laptop’s connector.

This Mod also allows you to turn your PSP on or off through the controller. All buttons also function well, especially the joystick.

There’s no detail info on how you could purchase those connectors, or step-by-step guide, but the close up gallery shows you how it looks like, and how it works.
