You could probably do this with a buffer or OR gate chip (both inputs wired together) to the switch, then each gate output to the different system. I think that a 7400 series TTL or 4000 series CMOS logic gate chip may be a good bet. Using these TTL/CMOS chip allows the same button to input for both, but prevent a wiring backfeed from one to the other.

: This may sound ridiculous to you EE fellas, but I really don't know; can you simply run two wires from the same pushbutton microswitch, one to a keyboard encoder, the other to a hacked gamepad, such that when the pushbutton is pressed, signals are sent to both units? This would allow you to keep functionality for a lot more non-emu computer programs, especially older games which don't support game pads, but still allow you to play console games in the cabinet, and without the cost of additional controller converters.
