WIP:

0.126u4: Changed 68000 CPU1 clock speed to 8MHz.
0.119u1: Stephane Humbert added some notes to Operation Wolf driver.
0.119: David Haywood added clone Operation Wolf (World, set 2). I don't know what this set changes. There is a single byte changed near the end of the roms, just after the copyright strings, however, it is not the region byte. This set came from a 100% legitimate Taito PCB with original labels. It would be easy just to write this off as a bad read / hacked rom but the bootleg version has exactly the same change and the label is different (b20-17 instead of b20-20) so this seems unlikely. Changed description of clone 'Operation Bear' to 'Operation Bear (bootleg of Operation Wolf)'.
0.118u3: Stephane Humbert cleaned up several Taito drivers to use common input port macros. Fixed the dipwitches for all games (a few still remain unknown though) and added many notes. Improved the C-chip emulation for "Operation Wolf" and its clones so it can now handle multiple coinage settings.
0.104u4: Adam Bousley fixed save states in Operation Wolf.
0.98u1: Nicola Salmoria fixed crash in Volfied and Operation Wolf due to improper timer usage.
0.97u1: Bryan McPhail added proper C-chip emulation to Operation Wolf (machineopwolf.c). Added 2nd sound channel. Removed 2nd Z80 CPU and cpu3 rom. Fixed different gun offsets of the World version.
0.95u3: Bryan McPhail added Operation Wolf (World). Renamed (opwolf) to (opwolfu).
0.93u2: Nicola Salmoria fixed sound in Operation Wolf.
0.93: Changed ADPCM sound to MSM5205 (384000 Hz).
30th March 2001: David Graves and Jarek Burczynski fixed a few bugs and added state saving support to Rainbow Islands, Rastan and Operation Wolf.
0.37b13: Changed description of clone Operation Wolf (bootleg) to 'Operation Bear' (bootleg 1987).

- 0.37b11: David Graves and Jarek Burczynski added Operation Wolf (US) (Taito 1987) and clone (bootleg). TODO: There are a few unmapped writes for the sound Z80 in the log. What number should be returned for the c-chip Z80 interrupt? 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.

23rd December 2000: Gerardo Oporto fixed dip switch settings in Operation Wolf / Thunderbolt and the dual screen games.
7th December 2000: David Graves sent in a working Operation Wolf driver done by him and Jarek Burczynski.
11th November 2000: David Graves sent in preliminary Operation Wolf / Operation Thunderbolt drivers, however only Operation Thunderbolt works.
