I have a couple of "nits" to point out: 1) the two Apple keys are not "function" keys (which deliver a key code), but "modifier" keys, like Shift and Control. 2) You refer to the internal game port as "a set of pins" when it would be more descriptive to say, "a 16-pin DIP socket".
No. The Apple keys are push button switches and require software control. Modifiers such as the shift key function in hardware. It is possible for software to react to the switches in a function oriented manner. Such software will also react to the push buttons on a joystick.
