hello,
i just carried out my first psp hardware mod, i love racing games and ever since i got my psp i couldnt beleive how unresponsive the thumb nub was. I opened it up once with a veiw to adding a steering wheel but i couldnt work out how to wire it. Then last week i read an article about Benjamin Heckendorn "porting", hacking, a ps2 analogue stick onto his psp. That was it Ben showed me the light, although he just wired it and had the wires hanging out, i didn't like this so i added a mini usb type port to my psp and a mini usb connector to my stick, this makes it detachable and adds scope to making different addons (steering wheel). Thanks to Benjamin Heckendorn, without his schematics i wouldn't have been able to do this, now my psp feels whole.
I'm including some photos and a link to a video i posted on youtube.
