/*  This define is for the few that can plug a real Williams sound
 *  board on the parallel port of their PC.
 *  You will have to recompile MAME as there is no command line option
 *  to enable that feature.
 *
 *
 *      You have to plug it correctly:
 *       Parallel  Sound board (J3)
 *     Pin  2           3
 *     Pin  3           2
 *     Pin  4           5
 *     Pin  5           4
 *     Pin  6           7
 *     Pin  7           6
 *
 *     Pin  18         GND (Any ground pin on the board)

 To Do:
  -Special numbers:

   42 or 44? play a note on Defender only.
   ?? play a Sinistar voice sample
  -In Splat, the last samples cannot be interrupted (from 57 to 63)

 Done:
  -In Robotron do not restart the sound 49 when wave change
