ZG board (c) 1991 Alba

driver by Angelo Salese

Notes:
-The name of this hardware is "Alba ZG board",a newer revision of the
 "Alba ZC board" used by Hanaroku (albazc.c driver). Test mode says clearly that this is
 from 1991.

TODO:
-Player-2 inputs are unemulated;
-"Custom RAM" emulation: might be a (weak) protection device or related to the "Back-up RAM NG"
 msg that pops up at every start-up.
-Video emulation requires a major conversion to the HD46505SP C.R.T. chip (MC6845 clone),
 there's an heavy x offsetting with the flip screen right now due of that (sets register
 0x0d to 0x80 when the screen is upside-down)
-You can actually configure the coin chutes / coin lockout active high/low (!), obviously
 MAME framework isn't really suitable for it at the current time;

PCB:
- HD46505SP-2 / HD68B45SP Japan
- Mostek MK3880P CPU, Z80 clone
- NEC D8255AC-2
- AY38910A/P
- X1-009 (labeled 8732K5), X1-0198 (or X1-019B, can't read)
- X2-004, X2-003, AX-014 (all with epoxy modules apparently)
- X1-007
- CR-203 lithium battery, near X1-009 and X1-0198. There is also a switch near it
- Xtal 12 MHz at top right corner
