+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 socketted 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.

+
+
+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'
+ but its effect is unknown as this address doesn't seem to be read !
+
+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.c) :
+ * 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
+====
+
+Need to verify Opwolf against original board: various reports
+claim there are discrepancies (perhaps limitations of the fake
+Z80 c-chip substitute to blame?).
+
+There are a few unmapped writes for the sound Z80 in the log.
+
+Unknown writes to the MSM5205 control addresses
+
+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.
