 a.k.a. same Jangou blitter but with NCS CPU for displaying graphics as protection.

 preliminary driver by David Haywood & Angelo Salese
+many thanks to Charles MacDonald for the schematics / documentation of this HW.

 TODO:
-Get Night Gal Summer and Royal Queen to boot;
+-Get Night Gal Summer to boot;
 -Fix Sweet Gal/Sexy Gal gfxs if necessary (i.e. if the bugs aren't all caused by irq/nmi
 wrong firing);
 -Proper Z80<->MCU comms,many video problems because of that;
 -Abstract the video chip to a proper video file and get the name of that chip;
+-Minor graphic glitches in Royal Queen (cross hatch test, some little glitches during gameplay),
+ presumably due of the unemulated wait states on the comms.
