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.

/*** Rom Loading ***
we currently have two dumps, one appears to be a world/us version, the
other is clearly a Japan version as it displays a regional warning
there is also a bad dump which for reference has the following roms
different to the world dump
"24.rom" 0x10000 0x39a2d923 (code)
"25.rom" 0x10000 0x9a0a9cd6 (code / data)
"21.rom" 0x10000 0x93651858 (gfx)
"22.rom" 0x10000 0xee7561d9 (gfx)
"23.rom" 0x10000 0x46b3c186 (gfx)
this fails its rom check so I assume its corrupt
