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

    Double Dragon 3                     Technos Japan Corp 1990
    The Combatribes                     Technos Japan Corp 1990


    Notes:

    Both games have original and bootleg versions supported.
    Double Dragon 3 bootleg has some misplaced graphics, but I
    think this is how the real thing would look.
    Combatribes has sprite lag but it seems to be caused by poor
    programming and I think the original does the same.
