    CES Classic wall games

    driver by Angelo Salese

    Notes:
    - to play Home Run Classic you have to select a pitcher shot and keep pressed the
      wall strobe. When you release the strobe, batter does the swing.

    TODO:
    - custom layout for dual LCDs
    - artwork and lamps position needed to make progresses
    - U43 and U44 bad in Trap Shoot Classic
    - games are incredibly sluggish by now
    - irq sources are unknown
    - sound doesn't play most samples
    - Trap Shoot Classic runs on a single LCD, needs mods
