Notes:
- master/slave 4 players mode is not emulated at all.
To set it up, enable the Master/Slave Mode and set the two boards IDs with
different settings. Do NOT enable the Single board 4p mode, I don't think
that the main board is supposed to be still connected to the sub board.
- Single board 4 players mode actually works but I'm not sure how the reset /
halt line is truly connected on the sub CPU.
To set it up, just enable the single board 4p mode and keep the master/slave
mode to off and the board ID to master.
- mexico86 does a PS4 STOP ERROR shortly after boot, but works afterwards. PS4 is
the MC6801U4 MCU, the bootleggers replaced it with a custom programmed 68705 MCU.
- Kick and Run is a rom swap for Kiki KaiKai as the pal chips are all A85-0x
A85 is the Taito rom code for Kiki KaiKai. Even the MCU is socketed!

Notes:
E - 50 pin flat cable connector labelled 'E' (unused)
A85-01.H8 - Motorola MC6801U4 8-bit microcontroller with 192 Bytes internal RAM and 4kB internal mask ROM marked 'TAITO A85-01 JPH1020P 185 PS4 J8641'
Clock input 3.000MHz on pin 3 [24/8]
CN1 - 4-pin header labelled 'JAMMA' with a 4-pin plug marked 'H' connected on top.
Pin 1 is tied to ground.
Pin 2 is tied to the PC050CM on pin 10 (schematics show pin 10 is tied to ground).
Each of the pins 3 and 4 connect to the JAMMA 12V pins separately (JAMMA 12V is not tied together on the PCB).
On the 'H' plug, pins 1-2 are tied with a wire and pin 3-4 are tied with a wire.
MB3731 - Fujitsu MB3731 18W BTL mono power amplifier
MB3771 - Fujitsu MB3771 power supply monitor IC. This is used to provide the power-on reset.
SWA/SWB - 8-position DIP switch
TMM2064 - Toshiba TMM2064 8kx8-bit static RAM
MCM2016 - Motorola MCM2016 2kx8-bit static RAM
CXK5816 - Sony CXK5816 2kx8-bit static RAM
4556 - 4556 dual operational amplifier
VOL - 5k volume pot
PC050CM - Taito PC050CM custom SIL28 ceramic module for coins, coin lockout and coin counters
YM3014 - Yamaha YM3014 serial input floating D/A converter. Clock input 1.000MHz on pin 5 [24/24]. Other clocks: pin 3= 41.6666kHz, pin 4= 83.3332kHz
YM2203C - Yamaha YM2203C OPN (FM Operator Type-N) 3-channel sound chip. Clock input 3.000MHz [24/8]
