  Tao Taido             (c) 1993 Video System


    driver by David Haywood - Dip Switches and Inputs by Stephane Humbert
    based on other Video System drivers

Stephh's notes (based on the games M68000 code and some tests) :

0) all games

  - Don't trust the test mode ! It shows inputs for 4 players as well as
    3 buttons for each player, while the game is a 2 players game with only
    2 buttons (punch and kick) for each player.
    IMO, it's a leftover from a previous game.
    If you want to test all inputs, turn TAOTAIDO_SHOW_ALL_INPUTS to 1.

  - The "Buy-In" features allows a player to recover some energy and reset timer
    by pressing his "Start" button (provided he has at least one credit).

  - 'taotaido' allows to play a 2 players game with a single credit while
    this isn't possible with 'taotaida'.
    Now, telling which version is the newest one is another story ;)

  - 'taotaido' seems to show you how to do the special moves, 'taotaida' doesn't
    and they don't seem to work in the same way (unless this is a bug)

  - Coin buttons act differently depending on the "Coin Slot" Dip Switch :

      * "Coin Slot" Dip Switch set to "Same" :

          . COIN1 : adds coin(s)/credit(s) depending on "Coinage" Dip Switch
          . COIN2 : adds 1 credit
          . SERVICE1 : adds coin(s)/credit(s) depending on "Coinage" Dip Switch

      * "Coin Slot" Dip Switch set to "Individual" :

          . COIN1 : adds coin(s)/credit(s) for player 1 depending on "Coinage" Dip Switch
          . COIN2 : adds coin(s)/credit(s) for player 2 depending on "Coinage" Dip Switch
          . SERVICE1 : adds 1 credit for player 1
