I've seen a few other threads and information on hacking a NES controller to hook up to your PC through paralell port..
but how about if you have the NES itself.. is there anyway to hack the controller jack portion?
So it would look like this... NES controller -> NES plug -> hack to paralell or wherever.
It would be cool to not only use authentic controllers.. but have the authentic port for it too... plus would make it easily detachable on the front of a cabinet..
