Nes Controller Port Wiring Question for bar top.

  As long as you complete whatever loop, you should be able to wire it however you want.

  So i'm currently starting design of an NES bar top arcade and I have a controller wiring question.  So i know typically you dissect the controller and solder the joystick and arcade button wires direct to the PCB.  I am wondering is it possible to have the controller wired in and the port itself in case someone wants to use a controller instead.
  
  
  
  So basically you would have the arcade controls up top AND a port on the front to plug in to. 
  
  
  
  What I am thinking is solder the arcade controls directly to the controller PCB and the hard wire the controller after the port and mount the port on the front of the machine.
  
  
  
   

  
  It's perfectly possible. What you'd have is a port on the outside and basically a controller on the inside.
  
  
  
  What I would do, is to have the controller board where the arcade buttons attach to, separate the cable from it, then use some diodes to make sure you don't get any signal back into the controller board... if I can, I'll draw a circuit diagram later tonight or tomorrow, it's really a quick and easy fix.
  
  
  
  EDIT:
  
  
  
  Okay, now that I've had some time to think about it a bit more, here's what you can do. Use a controller board for the bar top arcade style controller, take the cable off of that. Wire the original signals from the board to a separate small PCB (think perfboard) and let the signals from the bar controller go through a set of diodes. Then at the and, attach the original cable to transport the signal to the machine in question.
  
  
  
  If you do something similar with the signals coming from the controller port, and just wire them up to the same output, you should be done. So you'd factually attach 2 controllers to a small board, which makes sure there's diodes on every signal line and then you have a 2 to 1 conversion board.
  
  
  
  Make sure to not put a diode on the clock and latch lines though, otherwise you'll have a non-functioning controller on your hand. This is because the NES latches and clocks the internal circuit that captures the button presses. 
  
  
  
  I hope this helps.
