+
+ Tao Taido (c) 1993 Video System
+
+
+ driver by David Haywood - Dip Switches and Inputs by stephh
+ 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
