Baraduke (c) 1985 Namco
Metro-Cross (c) 1985 Namco
Driver by Manuel Abadia <manu@teleline.es>
The sprite and tilemap generator ICs are the same as in Namco System 86, but
System 86 has two tilemap generators instead of one.
Custom ICs:
----------
98XX lamp/coin output
99XX sound volume
CUS27 clock divider
CUS30 sound control
CUS31
CUS39 sprite generator
CUS41 address decoder
CUS42 dual scrolling tilemap address generator
CUS43 dual tilemap generator
CUS48 sprite address generator
CUS60 MCU (63701) aka 60A1

Namco Customs:
27 : DIP40, manufactured by Fujitsu)
30 : (SDIP64)
31 : (DIP48, also written on chip is '218' and '5201')
39 : (DIP42, manufactured by Fujitsu)
41 : (DIP40, also written on chip is '8512MAD' and 'PHILIPPINES')
42 : (QFP80, the only chip on the PCB that is surface-mounted)
60A1 : (DIP40, known 63701 MCU)
43 : (SDIP64)
48 : (SDIP64)
ROMs:
PR1.1N is a PROM type MB7138E
PR2.2M is a PROM type MB7128E
BD1_3.9C & BD1_5.3J are 2764 EPROMs. All other ROMs are 27128 EPROMs.
Notes:
-----
- in floor 6 of baraduke, there are gaps in the big boss when the player moves.
This is the correct behaviour, verified on the real board.
TODO:
----
- The two unknown writes for the MCU are probably watchdog reset and irq acknowledge,
but they don't seem to work as expected. During the first few frames they are
written out of order and hooking them up in the usual way causes the MCU to
stop receiving interrupts.
- remove the sound kludge in Baraduke. This might actually be a feature of the
CUS30 chip.
