... I suppose that could work.
So you are suggesting
(EDIT:) to attach the NES controller to a USB adaptor;
to attach a USB gamepad to a PC;
The PC would translate the gamepad buttons into key presses;
the key presses would output through the paralel port and into the controller port.
That would require grabbing PC NES transfer cable v1.30 by sepi
from nesdev.parodius.comNES Dev
, and conficuring the PC to boot up into translation mode; cramming it inside the NES shell. and implementing a video switch between the NES and the PC... swallowing a spider to eat the fly...
(edit:) I don't know why I didn't think of that sooner. That would make much more sense to make a detachable adaptor from NES to PC.raphnet.net4 NES and/or 4 SNES controller(s) to USB
