Connect 2 controllers into a single port?
I know this is an odd question, but I'm making an NES, bar-top arcade using 2 NES Advantage joysticks as the primary controllers. However, I thought it would be great to have the light-gun or classic controller available as well, but without having to manually un-plug one, then plug-in the other.
Would it be possible to have multiple, controllers wired into a single port, or would it negatively affect the voltage to the point of not working?
┌── Controller 1
├─> NES (Player 1 port)
└── Controller 2
After considerable research, it looks like there are two options ...
A 6PDT switch (since one connection is just a ground wire) -- Enabling controllers to be selected by flipping the switch.
Or, have each wire split between controllers using a 2 input diode AND gate.
