Karate Champ - (c) 1984 Data East
driver by Ernesto Corvi
Changes:
(1999/11/11 Takahiro Nogi)
Changed "karatedo" to "karatevs".
Supported "karatedo".
Corrected DIPSW settings.(kchamp/karatedo)
Currently supported sets:
Karate Champ - 1 Player Version (kchamp)
Karate Champ - VS Version (kchampvs)
Karate Champ - 1 Player Version Japanese (karatedo)
Karate Champ - VS Version Japanese (karatevs)
VS Version Info:
---------------
Memory Map:
Main CPU
0000-bfff ROM (encrypted)
c000-cfff RAM
d000-d3ff char videoram
d400-d7ff color videoram
d800-d8ff sprites
e000-ffff ROM (encrypted)
Sound CPU
0000-5fff ROM
6000-6300 RAM
IO Ports:
Main CPU
INPUT 00 = Player 1 Controls - ( ACTIVE LOW )
INPUT 40 = Player 2 Controls - ( ACTIVE LOW )
INPUT 80 = Coins and Start Buttons - ( ACTIVE LOW )
INPUT C0 = Dip Switches - ( ACTIVE LOW )
OUTPUT 00 = Screen Flip? (There isnt a cocktail switch?) UNINMPLEMENTED
OUTPUT 01 = CPU Control
bit 0 = external nmi enable
OUTPUT 02 = Sound Reset
OUTPUT 40 = Sound latch write
Sound CPU
INPUT 01 = Sound latch read
OUTPUT 00 = AY8910 #1 data write
OUTPUT 01 = AY8910 #1 control write
OUTPUT 02 = AY8910 #2 data write
OUTPUT 03 = AY8910 #2 control write
OUTPUT 04 = MSM5205 write
OUTPUT 05 = CPU Control
bit 0 = MSM5205 trigger
bit 1 = external nmi enable
1P Version Info:
---------------
Same as VS version but with a DAC instead of a MSM5205. Also some minor
IO ports and memory map changes. Dip switches differ too.
