I have a question regarding the A-PAC shift function - The graphic here:
http://www.ultimarc.com/a-pac.html (also shown below), implies that every input can be shifted, giving 28 inputs and the 4 directionals per joystick. The text also says that the C input is used as the shift function. Normally the C button is read as Button 11. How do I get the "Shifted C button" to register as button 27. If it's a double press, then the A-PAC can't differentiate between sending a button 27 and a double button 11. If it's a long key press, then wouldn't the A-PAC send 11 and then 27, rather than just 27. Perhaps the Player 2 C button shifts the inputs for Player 1 C, but I assumed from everything else I have read that the two sides of the board were independent.
On the I-PAC the shift button cannot send a shifted input. I would think this was true on the A-PAC as well, but the graphic is supposed to be an actual screen capture and shows 28 buttons and an analog joystick, so something is not adding up to me, or maybe I'm missing something really obvious due to caffienne (sp?) deprivation?
