I plan to make an all in one n64, NES, SNES, SEGA, Atari to usb adapter so i could just plub in the controller and set it up in the emulator controll options, i know this could be done somehow but i do not know about converting the pcb output into somthing recognizable by windows usb, has anyone tried this or know anyinformation about how the pcbs in these controllers work? i know they make a SNES to usb, a ps2 to usb, and an xbox to usb, but i wanted to make like a little adapter with the electronics inside to convert all of these to one usb connection
easiest way would be to make each of the individual adapters then connect them to a small usb hub enclose all in one project box and voila there you go!
Have you tryed GOOGLE? there are loads of these out there. what your looking for is 2 items 1st converts pad sig to usb, 2nd tells winbloze what to do with the signal.
