        ToaPlan game hardware from 1987
        --------------------------------
        Driver by: Quench


Supported games:

    Toaplan Board Number:   TP-009
    Taito Game Number:      B25
        Wardners Forest (World)
        Pyros           (USA)
        Wardna no Mori  (Japan)

Notes:
        Basically the same video and machine hardware as Flying shark,
          except for the Main CPU which is a Z80 here.
        See twincobr.c machine and video drivers to complete the
          hardware setup.
        Also see Input Port definition header below, for instructions
          on how to enter test mode.
