/***************************************************************************

    Green Beret
    Konami

    driver by Nicola Salmoria
    correct ROM naming information by Belgium Dump Team (17/06/2003)

    Games supported:
        * Green Beret
        * Rush'n Attack (US)
        * Green Beret (bootleg)
        * Mr. Goemon (Japan)

    gberetb is a bootleg hacked to run on different hardware.

    TODO
        - Measure IRQ and NMI frequency (of an original board), is IRQ really tied to the same timer that triggers NMI?
        - Correct PROMs decoding for the bootleg
