"This mod done by Blizzrad of AcidMods lets you use your aging wired DualShock controller and hook it up to your PSP. The controller had its connector replaced for a much smaller one to elegantly fit in with the PSPs slim build. The mod also takes full use of the controller's second analog stick and extra shoulder buttons. The only commands not controlled by the DualShock are backlight and volume control."

Wow impressive but kinda useless unless you have button problems with your psp then it's a godsend.

Nice. I really wish they'd included a controller port on the PSP (or at least a way to hook one in through the USB port). The button layout on that thing is murder on the thumbs. It would also make hooking it up to a TV much more practical, and could allow for 2-player in certain instances (sort of like the Sega Nomad).
