Yes. A gamepad has some extra components in it, normally just a few
transistors, to switch between the three simulated joystick positions in
each axis e.g. left, center, right. Like an auto-fire circuit it requires +5
volts to operate properly, so you'll need to use the other circuit in the
FAQs.

I have a PC gamepad connected to my IIe via an adaptor similar to the
auto-fire supporting one in the FAQ and it works fine.
