3 Operation Wolf (c) Taito 1987
4 ==============
5
6 David Graves, Jarek Burczynski
7 C-Chip emulation by Bryan McPhail
8
9 Sources: MAME Rastan driver
10 MAME Taito F2 driver
11 Raine source - many thanks to Richard Bush
12 and the Raine Team.
13
14 Main CPU: MC68000 uses irq 5.
15 Sound : Z80 & YM2151 & MSM5205
16
17
18 Operation Wolf uses similar hardware to Rainbow Islands and Rastan.
19 The screen layout and registers and sprites appear to be identical.
20
21
22 Gun Travel
23 ----------
24
25 Horizontal gun travel maybe could be widened to include more
26 of the status bar (you can shoot enemies underneath it).
27
28 To keep the input span 0-255 a multiplier (300/256 ?)
29 would be used.
30
31
32 TODO
33 ====
34
35 There are a few unmapped writes for the sound Z80 in the log.
36
37 Unknown writes to the MSM5205 control addresses
38
39 Raine source has standard Asuka/Mofflot sprite/tile priority:
40 0x2000 in sprite_ctrl puts all sprites under top bg layer. But
41 Raine simply kludges in this value, failing to read it from a
42 register. So what is controlling priority.
