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

Tag Team Wrestling hardware description:

This hardware is very similar to the BurgerTime/Lock N Chase family of games
but there are just enough differences to make it a pain to share the
codebase. It looks like this hardware is a bridge between the BurgerTime
family and the later Technos games, like Mat Mania and Mysterious Stones.

The video hardware supports 3 sprite banks instead of 1
The sound hardware appears nearly identical to Mat Mania


Stephh's notes :

  - When the "Cabinet" Dip Switch is set to "Cocktail", the screen status
    depends on which player is the main wrestler on the ring :

      * player 1 : normal screen
      * player 2 : inverted screen

TODO:
        * fix hi-score (reset) bug
