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    (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.

TODO :
========
 - Make dipswitches clear.
 - 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.
