    P&P Marketing Police Trainer hardware

    driver by Aaron Giles

    Games supported:
        * Police Trainer
        * Sharpshooter

    Known bugs:
        * Flip screen not supported

Note:   Police Trainer v1.3B runs on the same revision PCB as Sharpshooter - Rev 0.5B
        If you hold the test button down and boot the game, all program roms
        fail the checksum.  This has been verified on an original PCB.
        See below for specific information on each set.
Note:   Police Trainer v1.0 (Rev 0.2 PCB), the checksum results in MAME have been
        verified to be the same as an original PCB.

To ID the version of your SharpShooter, check the 2nd printed line on each type of ROM.

Program Roms:  C121012 - Code version 1.2, Graphics v1.0 & Sound v1.2
Graphic Roms:  G10     - Graphics rom v1.0 (in diagnostics mode it's called "Art")
  Sound Roms:  S12     - Sound rom v1.2

Noted differences in versions of SharpShooter:
 Initial High Score names are changed between v1.1 and v1.2
  Circus of Mystery:
    The ballon challenge has been rewritten for v1.7
    Jugglers throw balls painted with targets for v1.1 & v1.2  Version 1.7 uses regular targets
  Alien Encounter:
    First saucer challenge has been modified for v1.7

The ATTILA Video System PCB (by EXIT Entertainment):

Sharpshooter PCB is Rev 0.5B
Police Trainer PCB is Rev 0.3 / Rev 0.2

      checksums on the screen match the set below.  IE: U110=556D, U111=E5F1, U112=974C & U113=CB73

      However, if you check the Diagnostics screen, the program rom checksum is 6819480C which is different then the set below. So it
      looks like it's checking the extra code.  The roms do not contain identical halves, so it's unknown what the "new" data is or does.

      This set has also been found using mask roms for the program roms which would indicate it was the final version.
