Mod god Ben Heck has a great how-to on adding an analog joystick to a PSP, he writes – “History is littered with game systems using far-too-stubby of controller sticks. From the Intellivision’s “disc of doom,” to Coleco’s “shaft of stiffness” (quiet, you!), and even now, in this high-tech age, the Sony PSP’s “sliding nub of death.” It’s unfortunate that the PSP is saddled with that thing — it’s a pretty slick system otherwise, with a library of almost 5 games! (Please don’t key our cars.) Well what if you could augment that sliding nub with something more useful, like an actual analog control stick? Well now you can!” – Link.
