I don't suppose you guys could design a docking bay/adapter that acts as a remotejoy server with a port for ps2 controllers?
I'd love one with a USB port and bluetooth to use SIXAXIS/Dualshock3 but I'm pretty sure that's asking too much
you basically just asked us to build a small pc that will fit in a psp dock!
if your not to bothered, then why dont you just use your pc, nethost, irshell, glovepie (xbox con, ps3 con, wii con), a ps2 controller to usb adapter. then you can do what you just asked, and most of it is software based and it is all freeley available.
if you wanted it to be portable, then no, unless you carry a laptop arround with you.
or someone decides to do exactly what you asked and build a small pc inside a psp dock!
