I just tested it with Windows controller configuration settings, and it I think it seems that Mayflash have it set up correctly. When I begin to press the L/R buttons, I see the X/Y rotation level increase until it is fully pressed in (at which point the buttons light up, indicating they are pressed). I guess it's just that P64 detects for the X/Y rotation as well as the button press, but Dolphin just detects the button press? Either way it's good.
