 /**
+2008/06/11, by Naibo(translated to English by Mameplus team):
+Driver's Eyes works, 
+	-the communication work between CPU and 3D DSP should be limited to the master M68000, 
+	if the address mapping is done in the shared memory, master CPU would be disturbed by the slave one.
+
+	-DIP Switches
+	DIP3 ON for Screen on the left
+	DIP4 ON for Screen on the right
+	should not toggle on both
+
+	-The left, center and right screens have separate programs and boards, each would work independantly. 
+	About projection angles of left and right screen, the angle is correct on "DRIVER'S EYES" title screen, however in the tracks of demo mode it doesn't seem correct.
+
+	-On demo screen, should fog effects be turned off?
+
+	-The game also features a pretty nice 2D sprite layer, which still doesn't show up yet.
+	it is known that the CPU does constantly feed the 2D video memory some meaningful and logical data.
+
