    Would a crystal oscilator work? If so, what khz or mhz would you suggest?

    No. When an MD game use the pad, the game itself must control the state of the pin.
    It must work in a way like this:

    The game set the pin HIGH, then he read the values of the B and C buttons, then the game set the pin LOW, now, the game knows that the next button he read are A and START.
    If you feed an external clock, the game will not know which set of buttons are pressed.
    The clock can work on the SMS because no SMS games handle the pin 7 to use a 3 or 6 buttons PAD.
