I've always been toying with the idea of making a dedicated YDKJ panel: three over sized buttons for the buzzer, the five answer buttons (1, 2, 3, 4, Screw) and a small membrane keyboard. You just have to map the B,P,Q,S, and 1~4 keys, but it shouldn't be too hard.
BTW, of all the Jacks, "The Ride" (a/k/a 4) is my least favorite. Having the questions in a predetermined order kills replay, especially if you find yourself having to reinstall.
