	754	(Preliminary) explanation about this:
	755	VBLANK-OUT is used at the start of the vblank period.It also sets the timer zero
	756	variable to 0.
	757	If the Timer Compare register is zero too,the Timer 0 irq is triggered.
	758
	759	HBLANK-IN is used at the end of each scanline except when in VBLANK-IN/OUT periods.
	760
	761	The timer 0 is also incremented by one at each HBLANK and checked with the value
	762	of the Timer Compare register;if equal,the timer 0 irq is triggered here too.
	763	Notice that the timer 0 compare register can be more than the VBLANK maximum range,in
	764	this case the timer 0 irq is simply never triggered.This is a known Sega Saturn/ST-V "bug".
	765
	766	VBLANK-IN is used at the end of the vblank period.
	767
	768	SCU register[36] is the timer zero compare register.
	769	SCU register[40] is for IRQ masking.
	770
	771	TODO:
	772	- VDP1 timing and CEF emulation isn't accurate at all.

	3	Sega Saturn & Sega ST-V (Sega Titan Video) HW (c) 1994 Sega
	4
	5	Driver by David Haywood, Angelo Salese, Olivier Galibert & Mariusz Wojcieszek
	6	SCSP driver provided by R.Belmont, based on ElSemi's SCSP sound chip emulator
	7	CD Block driver provided by ANY, based on sthief original emulator
	8	Many thanks to Guru, Fabien, Runik and Charles MacDonald for the help given.

	10	===================================================================================================
	11
	12	Notes:
	13	-To enter into an Advanced Test Mode,keep pressed the Test Button (F2) on the start-up.
	14	-Memo: Some tests done on the original & working PCB,to be implemented:
	15	-The AD-Stick returns 0x00 or a similar value.
	16	-The Ports E,F & G must return 0xff
	17
	18	TODO:
	19	(Main issues)
	20	- decap the SH-1, used for CD block (needed especially for Sega Saturn)
	21	- IRQs: some games have some issues with timing accurate IRQs, check/fix all of them.
	22	- The Cart-Dev mode hangs even with the -dev bios,I would like to see what it does on the real HW.
	23	- IC13 games on the dev bios doesn't even load the cartridge / crashes the emulation at start-up,
	24	rom rearrange needed?
	25	- SCU DSP still has its fair share of issues, it also needs to be converted to CPU structure;
	26	- Add the RS232c interface (serial port), needed by fhboxers (accesses some ports in the a-bus dummy range).
	27	- Video emulation is nowhere near perfection.
	28	- Reimplement the idle skip if possible.
	29	- Properly emulate the protection chips, used by several games (check stvprot.c for more info)
	30	- Move SCU device into its respective file;
	31	- Split ST-V and Saturn files properly;
	32
	33	(per-game issues)
	34	- stress: accesses the Sound Memory Expansion Area (0x05a80000-0x05afffff), unknown purpose;
	35
	36	- smleague / finlarch: it randomly hangs / crashes,it works if you use a ridiculous MCFG_INTERLEAVE number,might need strict
	37	SH-2 synching or it's actually a m68k comms issue.
	38
	39	- groovef: ugly back screen color, caused by incorrect usage of the Color Calculation function.
	40
	41	- myfairld: Apparently this game gives a black screen (either test mode and in-game mode),but let it wait for about
	42	10 seconds and the game will load everything. This is because of a hellishly slow m68k sub-routine located at 54c2.
	43	Likely to not be a bug but an in-game design issue.
	44
	45	- danchih / danchiq: currently hangs randomly (regression).
	46
	47	- batmanfr: Missing sound,caused by an extra ADSP chip which is on the cart.The CPU is a
	48	ADSP-2181,and it's the same used by NBA Jam Extreme (ZN game).
	49
	50	- vfremix: when you play as Akira, there is a problem with third match: game doesn't upload all textures
	51	and tiles and doesn't enable display, although gameplay is normal - wait a while to get back
	52	to title screen after losing a match
	53
	54	- vfremix: various problems with SCU DSP: Jeffry causes a black screen hang. Akira's kick sometimes
	55	sends the opponent out of the ring from whatever position.

3		Sega Saturn & Sega ST-V (Sega Titan Video) HW (c) 1994 Sega
4
5		Driver by David Haywood, Angelo Salese, Olivier Galibert & Mariusz Wojcieszek
6		SCSP driver provided by R.Belmont, based on ElSemi's SCSP sound chip emulator
7		CD Block driver provided by ANY, based on sthief original emulator
8		Many thanks to Guru, Fabien, Runik and Charles MacDonald for the help given.
9
10		===================================================================================================
11
12		Notes:
13		-To enter into an Advanced Test Mode,keep pressed the Test Button (F2) on the start-up.
14		-Memo: Some tests done on the original & working PCB,to be implemented:
15		-The AD-Stick returns 0x00 or a similar value.
16		-The Ports E,F & G must return 0xff
17
18		TODO:
19		(Main issues)
20		- decap the SH-1, used for CD block (needed especially for Sega Saturn)
21		- IRQs: some games have some issues with timing accurate IRQs, check/fix all of them.
22		- The Cart-Dev mode hangs even with the -dev bios,I would like to see what it does on the real HW.
23		- IC13 games on the dev bios doesn't even load the cartridge / crashes the emulation at start-up,
24		rom rearrange needed?
25		- SCU DSP still has its fair share of issues, it also needs to be converted to CPU structure;
26		- Add the RS232c interface (serial port), needed by fhboxers (accesses some ports in the a-bus dummy range).
27		- Video emulation is nowhere near perfection.
28		- Reimplement the idle skip if possible.
29		- Properly emulate the protection chips, used by several games (check stvprot.c for more info)
30		- Move SCU device into its respective file;
31		- Split ST-V and Saturn files properly;
32
33		(per-game issues)
34		- stress: accesses the Sound Memory Expansion Area (0x05a80000-0x05afffff), unknown purpose;
35
36		- smleague / finlarch: it randomly hangs / crashes,it works if you use a ridiculous MCFG_INTERLEAVE number,might need strict
37		SH-2 synching or it's actually a m68k comms issue.
38
39		- groovef: ugly back screen color, caused by incorrect usage of the Color Calculation function.
40
41		- myfairld: Apparently this game gives a black screen (either test mode and in-game mode),but let it wait for about
42		10 seconds and the game will load everything. This is because of a hellishly slow m68k sub-routine located at 54c2.
43		Likely to not be a bug but an in-game design issue.
44
45		- danchih / danchiq: currently hangs randomly (regression).
46
47		- batmanfr: Missing sound,caused by an extra ADSP chip which is on the cart.The CPU is a
48		ADSP-2181,and it's the same used by NBA Jam Extreme (ZN game).
49
50		- vfremix: when you play as Akira, there is a problem with third match: game doesn't upload all textures
51		and tiles and doesn't enable display, although gameplay is normal - wait a while to get back
52		to title screen after losing a match
53
54		- vfremix: various problems with SCU DSP: Jeffry causes a black screen hang. Akira's kick sometimes
55		sends the opponent out of the ring from whatever position.

1449		(Preliminary) explanation about this:
1450		VBLANK-OUT is used at the start of the vblank period.It also sets the timer zero
1451		variable to 0.
1452		If the Timer Compare register is zero too,the Timer 0 irq is triggered.
1453
1454		HBLANK-IN is used at the end of each scanline except when in VBLANK-IN/OUT periods.
1455
1456		The timer 0 is also incremented by one at each HBLANK and checked with the value
1457		of the Timer Compare register;if equal,the timer 0 irq is triggered here too.
1458		Notice that the timer 0 compare register can be more than the VBLANK maximum range,in
1459		this case the timer 0 irq is simply never triggered.This is a known Sega Saturn/ST-V "bug".
1460
1461		VBLANK-IN is used at the end of the vblank period.
1462
1463		SCU register[36] is the timer zero compare register.
1464		SCU register[40] is for IRQ masking.
