/**************************************************************************** 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, licenced 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 adress 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. ***************************************************************************/ /* Define clocks based on actual OSC on the PCB */ #define CPU_CLOCK (XTAL_16MHz / 2) /*
