/* Sega ST-V (Sega Titan Video)

a.k.a. known as a Sega Saturn for the Arcades.

Driver by David Haywood,Angelo Salese,Olivier Galibert & Mariusz Wojcieszek
SCSP driver provided by R.Belmont,based on ElSemi's SCSP sound chip emulator
CD Block driver provided by ANY,based on sthief original emulator
Many thanks to Guru,Fabien & Runik for the help given.

Hardware overview:
------------------
-two SH-2 CPUs,in a master/slave configuration.The master cpu is used to
boot-up and to do the most of the work,the slave one does extra work that could be
too much for a single cpu.They both shares all the existant devices;
-a M68000 CPU,used to drive sound(the SCSP chip).The program is uploaded via the
SH-2 cpus;
-a SMPC (System Manager & Peripheral Control),used to drive all the
devices on the board;
-a SCU (System Control Unit),mainly used to do DMA operations and to drive interrupts,it
also has a DSP;
-an (optional for the ST-V) SH-1 CPU,used to be the CD driver;
-An A-Bus,where the cart ROM area is located;
-A B-Bus,where the Video Hardware & the SCU sections are located;
-Two VDPs chips(named as 1 & 2),used for the video section:
 -VDP1 is used to render sprites & polygons.
 -VDP2 is for the tilemap system,there are:
 4 effective normal layers;
 2 roz layers;
 1 back layer;
 1 line layer;
 The VDP2 is capable of the following things (in order):
 -dynamic resolution (up to 704x512) & various interlacing modes;
 -mosaic process;
 -scrolling,scaling,horizontal & vertical cell scrolling & linescroll for the
  normal planes, the roz ones can also rotate;
 -versatile window system,used for various effects;
 -alpha-blending,refered as Color Calculation in the docs;
 -shadow effects;
 -global rgb brightness control,separate for every plane;

this hardware comes above hell on the great list of hellish things as far as emulation goes anyway ;-)

*the unused locations aren't known if they are really unused or not,needs verification,most
of them seem just mirrors of the previous valid memory allocated.

ToDo / Notes:
-------------

-To enter into an Advanced Test Mode,keep pressed the Test Button (F2) on the start-up.

(Main issues)
-complete the Master/Slave communication.
-clean up the IC13 rom loading.
-Clean-ups and split the various chips(SCU,SMPC)into their respective files.
-CD block:complete it & add proper CD image support into MAME.
-the Cart-Dev mode...we need the proper ST-V Cart-Dev bios to be dumped in order to
 make this work,but probably this will never be done...
-fix some strange sound cpu memory accesses,there are various issues about this.
-finish the DSP core.
-Complete the window system in VDP2 (Still in progress).
-Add the RS232c interface (serial port),needed by fhboxers.
-(PCB owners) check if the clocks documented in the manuals are really right for ST-V.
-SCSP to master irq: see if there is a sound cpu mask bit.
-Does the cpunum_set_clock really works?Investigate.
-We need to check every game if can be completed or there are any hanging/crash/protection
 issues on them.
-Memo: Some tests done on the original & working PCB,to be implemented:
 -The AD-Stick returns 0x00 or a similar value.
 -The Ports E,F & G must return 0xff
 -The regular BIOS tests (Memory Test) changes his background color at some point to
  several gradients of red,green and blue.Current implementation remains black.I dunno
  if this is a framebuffer write or a funky transparency issue (i.e TRANSPARENT_NONE
  should instead show the back layer).
 -RBG0 rotating can be checked on the "Advanced Test" menu thru the VDP1/VDP2 check.
  It rotates clockwise IIRC.Also the ST-V logo when the game is in Multi mode rotates too.
 -The MIDI communication check fails even on a ST-V board,somebody needs to check if there
  is a MIDI port on the real PCB...

(per-game issues)
-groovef: hangs soon after loaded,caused by two memory addresses in the Work RAM-H range.
 Kludged for now to work.
-various: find idle skip if possible.
-suikoenb/shanhigw + others: why do we get 2 credits on startup with sound enabled?
-colmns97/puyosun/mausuke/cotton2/cottonbm: interrupt issues? we can't check the SCU mask
 on SMPC or controls fail
-mausuke/bakubaku/grdforce: need to sort out transparency on the colour mapped sprites
-bakubaku: no sound? Caused by missing irq?
-myfairld: Doesn't work with -sound enabled because of a sound ram check at relative
 addresses of $700/$710/$720/$730,so I'm not removing the NOT_WORKING flag due of that.Also
 Micronet programmers had the "great" idea to *not* use the ST-V input standards,infact
 joystick panel is mapped with input_port(10) instead of input_port(2),so for now use
 the mahjong panel instead.
-kiwames: the VDP1 sprites refresh is too slow,causing the "Draw by request" mode to
 flicker.Moved back to default ATM...
-pblbeach: Sprites are offset, because it doesn't clear vdp1 local coordinates set by bios,
 I guess that they are cleared when some vdp1 register is written (kludged for now)
-decathlt: Is currently using a strange protection DMA abus control,and it uses some sort of RLE
 compression/encryption that serves as a gfxdecode.
-vmahjong: the vdp1 textures are too dark(women).
-findlove: controls doesn't work?
-Weird design choices:
 introdon: has the working button as BUTTON2 and not BUTTON1
 batmanfr: BUTTON1 isn't used at all.
-seabass: Player sprite is corrupt/missing during movements,caused
 by incomplete framebuffer switching.
-sss: Missing backgrounds during gameplay. <- seems just too dark (night),probably
 just the positioning isn't correct...
-elandore: Polygons structures/textures aren't right in gameplay,known as protection
 for the humans structures,imperfect VDP1 emulation for the dragons.
-hanagumi: ending screens have corrupt graphics. (*untested*)
-batmanfr: Missing sound,caused by an extra ADSP chip which is on the cart.The CPU is a
 ADSP-2181,and it's the same used by NBA Jam Extreme (ZN game).
-twcup98: missing Tecmo logo
-vfremix: when you play Akira, there is a problem with third match: game doesn't upload all textures
 and tiles and doesn't enable display, although gameplay is normal - wait a while to get back
 to title screen after loosing a match
-sokyugrt: gameplay seems to be not smooth, timing?
-kiwames: hangs on title screen
-seabass: crashes in stvcd.c - there is no CD and we report than we have one, and game tries
 to read something, however it doesn't do it after nvram is deleted?
-Here's the list of unmapped read/writes:
*<all games>
cpu #0 (PC=0000365C): unmapped program memory dword write to 057FFFFC = 000D0000 & FFFF0000
cpu #0 (PC=00003654): unmapped program memory dword write to 057FFFFC = 000C0000 & FFFF0000
*bakubaku:
cpu #0 (PC=0601022E): unmapped program memory dword write to 02000000 = 00000000 & FFFFFFFF
cpu #0 (PC=0601023A): unmapped program memory dword write to 02000000 = 00000000 & FFFFFFFF

/*
(Preliminary) explaination about this:
VBLANK-OUT is used at the start of the vblank period.It also sets the timer zero
variable to 0.
If the Timer Compare register is zero too,the Timer 0 irq is triggered.

HBLANK-IN is used at the end of each scanline except when in VBLANK-IN/OUT periods.

The timer 0 is also incremented by one at each HBLANK and checked with the value
of the Timer Compare register;if equal,the timer 0 irq is triggered here too.
Notice that the timer 0 compare register can be more than the VBLANK maximum range,in
this case the timer 0 irq is simply never triggered.This is a known Sega Saturn/ST-V "bug".

VBLANK-IN is used at the end of the vblank period.

SCU register[36] is the timer zero compare register.
SCU register[40] is for IRQ masking.

Critter Crusher EXP
Sega, 1995.

This is a cart for Sega STV system. The game involves hitting 'critters' on
screen with a rubber/plastic hammer. The cab has a large LED display to show how many
'critters' were hit. The hammer positioning might work like a lightgun and the 'hitting'
may be like pulling the lightgun trigger?

The ROM cart appears to be a re-used Virtua Fighter Remix cart??
On top there is one 27C040 EPROM, EPR-18821 @ IC13
6 maskROMs, MPR-17945 to MPR-17950 (already dumped, known Virtua Fighter Remix ROMs)
On the other side of the PCB are 2 more maskROMs, MPR-18788 @ IC9 and MPR-18789 @ IC8

(number after the dot) = game version/release
There is also another internal code (called the "Product Number"),but AFAIK it's only used
by introdon in ST-V ("SG0000000"),and according to the manual it's even wrong! (SG is used
by Sega titles,and this is a Sunsoft game)It's likely to be a left-over...
