This chip mainly exists in F2-System games.
It seems to behave slightly differently in most games (banking methods,
disable methods, offset methods). Horrible.

/* Yeah quite horrible indeed. Anyway mame has done an incredible work about this chip too
   I almost converted "as is" their draw_sprite function for the taito f2 driver.
   Here is their information :

		Sprite format:
		0000: ---xxxxxxxxxxxxx tile code (0x0000 - 0x1fff)
		0002: xxxxxxxx-------- sprite y-zoom level
		      --------xxxxxxxx sprite x-zoom level

			  0x00 - non scaled = 100%
			  0x80 - scaled to 50%
			  0xc0 - scaled to 25%
			  0xe0 - scaled to 12.5%
			  0xff - scaled to zero pixels size (off)

		[this zoom scale may not be 100% correct, see Gunfront flame screen]

		0004: ----xxxxxxxxxxxx x-coordinate (-0x800 to 0x07ff)
		      ---x------------ latch extra scroll
		      --x------------- latch master scroll
		      -x-------------- don't use extra scroll compensation
		      x--------------- absolute screen coordinates (ignore all sprite scrolls)
		      xxxx------------ the typical use of the above is therefore
		                       1010 = set master scroll
		                       0101 = set extra scroll
		0006: ----xxxxxxxxxxxx y-coordinate (-0x800 to 0x07ff)
		      x--------------- marks special control commands (used in conjunction with 00a)
		                       If the special command flag is set:
		      ---------------x related to sprite ram bank
		      ---x------------ unknown (deadconx, maybe others)
		      --x------------- unknown, some games (growl, gunfront) set it to 1 when
		                       screen is flipped
		0008: --------xxxxxxxx color (0x00 - 0xff)
		      -------x-------- flipx
		      ------x--------- flipy
		      -----x---------- if set, use latched color, else use & latch specified one
		      ----x----------- if set, next sprite entry is part of sequence
		      ---x------------ if clear, use latched y coordinate, else use current y
		      --x------------- if set, y += 16
		      -x-------------- if clear, use latched x coordinate, else use current x
		      x--------------- if set, x += 16
		000a: only valid when the special command bit in 006 is set
		      ---------------x related to sprite ram bank. I think this is the one causing
		                       the bank switch, implementing it this way all games seem
		                       to properly bank switch except for footchmp which uses the
		                       bit in byte 006 instead.
		      ------------x--- unknown; some games toggle it before updating sprite ram.
		      ------xx-------- unknown (finalb)
		      -----x---------- unknown (mjnquest)
		      ---x------------ disable the following sprites until another marker with
			                   this bit clear is found
		      --x------------- flip screen

		000b - 000f : unused

		See the render_tc0200obj_mapped function for the implementation.
		The goal is to remove as many functions (exceptions) from this file
		as possible (because 1 function is MUCH easier to maintain).
