Taito H system
----------------------------
driver by Yochizo

This driver is heavily dependent on the Raine source.
Very thanks to Richard Bush and the Raine team. Also,
I have been given a lot of helpful informations by
Yasuhiro Ogawa. Thank you, Yasu.


Supported games :
==================
 Syvalion                           (C) 1988 Taito
 Record Breaker / Go For The Gold   (C) 1988 Taito
 Dynamite League                    (C) 1990 Taito


System specs :
===============
 CPU   : MC68000 (12 MHz) x 1, Z80 (4 MHz?, sound CPU) x 1
 Sound : YM2610, YM3016?
 OSC   : 20.000 MHz, 8.000 MHz, 24.000 MHz
 Chips : TC0070RGB (Palette?)
         TC0220IOC (Input)
         TC0140SYT (Sound communication)
         TC0130LNB (???)
         TC0160ROM (???)
         TC0080VCO (Video?)

 name             irq    resolution   tx-layer   tc0220ioc
 --------------------------------------------------------------
 Syvalion          2       512x400      used     port-based
 Record Breaker    2       320x240     unused    port-based
 Dynamite League   1       320x240     unused   address-based


Known issues :
===============
 - Y coordinate of sprite zooming is non-linear, so currently implemented
   hand-tuned value and this is used for only Record Breaker.
 - Sprite and BG1 priority bit is not understood. It is defined by sprite
   priority in Record Breaker and by zoom value and some scroll value in
   Dynamite League. So, some priority problems still remain.
 - A scroll value of text layer seems to be nonexistence.
 - Background zoom effect is not working in flip screen mode.
 - Sprite zoom is a bit wrong.
 - Title screen of dynamite league is wrong a bit, which is mentioned by
   Yasuhiro Ogawa.


Stephh's notes (based on the game M68000 code and some tests) :

1) 'syvalion'

  - Region stored at 0x07fffe.w
  - Sets :
      * 'syvalion' : region = 0x0000
  - Coinage relies on the region (code at 0x003640) :
      * 0x0000 (Japan), 0x0001 (US), 0x0003 (US, Romstar licence) and
        0x0004 (licenced to PHOENIX ELECTRONICS CO.) use TAITO_COINAGE_JAPAN_OLD
      * 0x0002 (World) uses TAITO_COINAGE_WORLD
  - Notice screen only if region = 0x0000
  - Text is always in Japanese regardless of the region !
  - DSW bit 6 has an unknown effect because of a write to unmapped 0x430000.w
    (see code at 0x002af8). Another write to this address is done at 0x002a96.


2) 'recordbr' and 'gogold'

  - Region stored at 0x07fffe.w
  - Title stored at 0x07ff9a.w :
      * 0x0000 : "Go For The Gold"
      * 0x0001 : "Recordbreaker"
  - Sets :
      * 'recordbr' : region = 0x0003 and title = 0x0001
      * 'gogold'   : region = 0x0001 and title = 0x0000
  - Coinage relies on the region (code at 0x00144a) :
      * 0x0001 (Japan), 0x0002 (US), 0x0005 (World, Romstar licence) and
        0x0006 (US, Romstar licence) use TAITO_COINAGE_JAPAN_OLD
      * 0x0003 (World), 0x0004 (licenced to xxx) and
        0x0007 (licenced to PHOENIX ELECTRONICS CO.) use TAITO_COINAGE_WORLD
  - Notice screen only if region = 0x0000 or region = 0x0001

  - Debug Mode (from Shimapong)
    1. Hold Service Switch at boot (key "9")
    2. Input the following sequence at the "Service Switch Error" message screen:
    1P Start, 1P Start, 1P Start, Service Switch, 1P Start


3) 'dleague'

  - Region stored at 0x05fffe.w
  - Sets :
      * 'dleague' : region = 0x0000
  - Coinage relies on the region (code at 0x0017be) :
      * 0x0000 (Japan) uses TAITO_COINAGE_JAPAN_OLD
      * 0x0001 (US) uses TAITO_COINAGE_US
      * 0x0002 (World) uses TAITO_COINAGE_WORLD
  - Notice screen only if region = 0x0000
  - FBI logo only if region = 0x0001
  - DSWA bit 0 determines if difficulty is constant or if it is based on the inning
    (code at 0x010964 and 0x0109ce + tables at 0x010afe and 0x010b18)
  - When region != 0, DSWB bit 0 has multiple effects
    (code at 0x001208 with $1206,A5 initialised via code at 0x00ae2c);
    here is what I found so far :
      * OFF : you can select your team, you starting pitcher and your batting order pattern,
              but there won't be additional messages ingame
      * ON  : you can't select your team, you starting pitcher and your batting order pattern,
              but there will be additional messages ingame
  - Regardless of the "Extra Credit Needed" settings, additional credit will be needed after 9th inning
    if there is a draw; the game will end if there is still a draw after 12th inning
  - The game will end if computer scores 10 points more than your score ("called game")
  - When you are playing, if you don't touch any joystick nor player button
    for 90 consecutive seconds, the game will end without any warning !
    See BTANB page on MAME Testers site for full report and more details


TODO :
========
 - Implemented BG1 : sprite priority. Currently it is not brought out priority
   bit.
 - Fix sprite coordinates.
 - Improve zoom y coordinate.
 - Text layer scroll if exists.
 - Speed up and clean up the code [some of video routines now in taitoic.c]

Dleague: junky sprites (sometimes) at bottom of screen in
flipscreen.

Recordbr: missing hand of opponent when he ends in swimming
race and you're still on the blocks. Bug?

Recordbr: loads of unmapped IOC reads and writes. Need to map Player 3 & 4 controls.

what is the rom loaded into region user1? (see go gold / dynamite league)
some kind of zoom table?
