+/*** Input Ports
+
+Haze's notes :
+
+There are controls for 4 players, each player has 4 directions and 2 buttons as
+well as coin and start. The service switch acts as inserting a coin for all
+4 players, the dipswitches are listed in the manual
+
+
+Steph's notes (2002.02.12) :
+
+I haven't found any manual, so my notes only rely on the Z80 code ...
+
+ -- Inputs --
+
+According to the Z80 code, here is the list of controls for each player :
+
+ - NO START button (you need to press BUTTON1n to start a game for player n)
+ - 4 or 8 directions (I can't tell for the moment, so I've chosen 8 directions)
+ - 2 buttons (I can't tell for the moment what they do)
+
+There are also 1 coin slot and a "Service" button for each player.
+
+1 "credit" will mean <<time defined by the "Player Time" Dip Switch>>.
+
+COINn adds one COIN for player n. When the number of coins fit the "Coinage"
+Dip Switch, 1 "credit" will be added.
+
+SERVICEn adds 1 "credit" for player n.
+
+There is also a GENERAL "Service" switch that adds 1 "credit" for ALL players.
+I've mapped it to the F1 key. If you have a better key and/or a better
+description for it, feel free to change it.
+
+ -- Dip Switches --
+
+According to the Z80 code, what is called "Difficulty" Dip Switch (DSW 1
+bits 0 and 1) doesn't seem to be tested. BTW, where did you find such info ?
+
+I haven't been able to determine yet the effect(s) of DSW3 bits 2 and 3.
+Could it be the "Difficulty" you mentioned that is HERE instead of DSW1
+bits 0 and 1 ? I'll try to have another look when the sprites stuff is finished.
