Acimods contributor [Blizzrad] has just finished one of the cleanest mods we’ve seen in a while. With minimal modification to the outside of the PSP he was able to add an external PS2 controller. This naturally took a lot of internal modification. The controller and PSP use a 25 pin SMT connector salvaged from a laptop. The controller’s connector housing is from a set of component cables. Video after the break plus some wiring pictures.
[Blizzrad] has put together a great wiring guide for the PSP/PS2 controller. It takes a lot of delicate work with 30AWG wire, but he’s done most of the hard work figuring out what vias you can use and where you should route wires. We love seeing people take the time to document difficult tasks like this.
