Operation Wolf (c) Taito 1987
==============
David Graves, Jarek Burczynski
C-Chip emulation by Bryan McPhail
Sources: MAME Rastan driver
MAME Taito F2 driver
Raine source - many thanks to Richard Bush
and the Raine Team.
Main CPU: MC68000 uses irq 5.
Sound : Z80 & YM2151 & MSM5205
Operation Wolf uses similar hardware to Rainbow Islands and Rastan.
The screen layout and registers and sprites appear to be identical.
Taito TC0030CMD chip labeled B20-18 (at least for the US boards)
Taito PC060HA looks like it might be a DIP28 Fujitsu MB884x chip
There are 4 socketed PALs (DIP20 type PAL16L8ACN) labeled B20-09
through B20-12 (not read)
OSC: Main board: 16MHz, 12MHz & 26.686MHz
Sound board: 8MHz (Next to Z80 & YM2151)
CPU: TS68000CP8 (Rated for 8MHz)
Gun Travel
----------
Horizontal gun travel maybe could be widened to include more
of the status bar (you can shoot enemies underneath it).
To keep the input span 0-255 a multiplier (300/256 ?)
would be used.

Notes:
PCB contains mostly caps/resistors and three small opto-related 8-pin ICs
CN1 - 4 pin connector joins to connector M on main board
Stephh's notes (based on the game M68000 code and some tests) :
1) 'opwolf' and 'opwolfu'
- Region stored at 0x03fffe.w
- Sets :
* 'opwolf' : region = 0x0003
* 'opwolfu' : region = 0x0002
- These 2 games are 100% the same, only region and gun offsets differ !
- Coinage relies on the region (code at 0x00bea4) :
* 0x0001 (Japan) and 0x0002 (US) use TAITO_COINAGE_JAPAN_OLD
* 0x0003 (World) and 0x0004 (Japan, licensed to Taito America ?) use TAITO_COINAGE_WORLD
- Gun offsets are stored at 0x03ffaf.b (Y) and 0x03ffb1.b (X);
these values are checked via routine at 0x000b76
- Notice screen only if region = 0x0001
- When "Language" Dip Switch is set to Japanese, you can also select your starting level;
however, only the 4 first levels are available ! Correct behaviour ?
- There's code at 0x00e090 that tests contents of 0x03ffb2.w :
if it is 0x0000, the highscore isn't displayed, but value = 0x00ff
2) 'opwolfa'
- Region stored at 0x03fffe.w
- Sets :
* 'opwolfa' : region = 0x0003
- There is only ONE byte of difference at 0x03fff5.b with 'opwolf'
it changes behaviour in the 'continue game' screen
3) 'opwolfb'
- Region stored at 0x03fffe.w
- Sets :
* 'opwolfb' : region = 0x0003
- Comparison with 'opwolf' :
* gun offsets are the same (so why are they different in the INIT function ?)
* all reference to TAITO and "Operation Wolf" have been changed or "blanked"
* "(c) 1988 BEAR CORPORATION KOREA" / "ALL RIGHTS RESERVED"
* ROM check test "noped" (code at 0x00bb72)
- Notes on bootleg c-chip (similar to what is in machine/opwolf.cpp) :
* always Engish language (thus the Dip Switch change to "Unused")
* round 4 in "demo mode" instead of round 5
* "service" button doesn't add credits (it works in the "test mode" though)
* if you die after round 6, difficulty isn't reset for the next game
TODO
====
There are a few unmapped writes for the sound Z80 in the log.
Unknown writes to the MSM5205 control addresses (RUN/RES implementation is wrong)
Sound volume filtering is imperfect. Notably the coin insert sound:
MSM1 rings it at volume 0xa8, MSM2 echos it at volume 0x84 but should be more muffled.
Raine source has standard Asuka/Mofflot sprite/tile priority:
0x2000 in sprite_ctrl puts all sprites under top bg layer. But
Raine simply kludges in this value, failing to read it from a
register. So what is controlling priority.
