    AmeriDarts      (c) 1989 Ameri Corporation
    Cool Pool       (c) 1992 Catalina
    9 Ball Shootout (c) 1993 E-Scape/Bundra

    driver by Nicola Salmoria and Aaron Giles


    The main cpu is a TMS34010; it is encrypted in 9 Ball Shootout.

    The second CPU in AmeriDarts is a TMS32015; it controls sound and
    the trackball inputs.

    The second CPU in Cool Pool and 9 Ball Shootout is a TMS320C26; the code
    is the same in the two games.

    Cool Pool:
    - The checksum test routine is wrong, e.g. when it says to be testing
      4U/8U it is actually reading 4U/8U/3U/7U, when testing 3U/7U it
      actually reads 2U/6U/1U/5U. The placement cannot therefore be exactly
      determined by the check passing.
