/*******************************************************************************************

Night Gal (c) 1984 Nichibutsu

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

preliminary driver by David Haywood & Angelo Salese

TODO:
-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;
