    P&P Marketing Police Trainer hardware

    driver by Aaron Giles

    Games supported:
        * Police Trainer
        * Sharpshooter

    Known bugs:
        * Flip screen not supported

Note:   For Police Trainer v1.3B sets that run on the same Rev 0.5B PCB as Sharpshooter: If you
        boot the game while holding the test button down until you get to the factory test screen,
        all program roms fail the checksum.  This result has been verified on original hardware.
        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.
Note:   Starting with Police Trainer v1.3B, support for high scores has been removed.

Note:   All versions of Police Trainer "claim" to be version 1.5 both in an audio sample and
        during the demo routine the screen shows: POLICE TRAINER   VERSION 1.5   The actual
        version can be verified by checking the labels or during the factory test. Boot (or
        reset) Police Trainer and hold the test button down to get the factory test screen.
        Police Trainer will show the actual "SOFTWARE REV", except for v1.0 which will show
        "FACTORY TEST"  To date, no version higher then v1.3B has been found and v1.2 has
        NEVER been seen.

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:
 Added a "Welcome to Sharpshooter" start-up screen showing rom versions for v1.9
 Initial High Score names are changed between v1.1 and v1.2
  Circus of Mystery:
    The balloon 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
