Cops 01 (c) 1985 Nichibutsu
Cop 01 (c) 1985 Nichibutsu
Mighty Guy (c) 1986 Nichibutsu
driver by Carlos A. Lozano <calb@gsyc.inf.uc3m.es>
TODO:
----
- Fix priority kludge (see video/cop01.c)
mightguy:
- missing emulation of the 1412M2 protection chip, used by the sound CPU.
- Inaccurate of the 1412M2 protection chip in mightguy, used by the sound CPU.
This is probably an extra CPU (program rom is the ic2 one), presumably
with data / address line scrambling
- Some sound problems remaining, not just 1412M2, but see also MT7949
Mighty Guy board layout:
