/*************************************************************************** Top Speed / Full Throttle (c) Taito 1987 ------------------------- David Graves Sources: Rastan driver by Jarek Burczynski MAME Taito F2 & Z drivers Raine source - special thanks to Richard Bush and the Raine Team. ***** Top Speed / Full Throttle is the forerunner of the Taito Z system on which Taito's driving games were based from 1988-91. (You can spot some similarities with Continental Circus, the first of the TaitoZ games.) The game hardware has 5 separate layers of graphics - four 64x64 tiled scrolling background planes of 8x8 tiles (two of which are used for drawing the road), and a sprite plane. Taito got round the limitations of the tilemap generator they were using (which only supports two layers) by using a pair of them. [Trivia: Taito employed the same trick three years later, this time with the TC0100SCN in "Thunderfox".] Top Speed's sprites are 16x8 tiles aggregated through a RAM sprite map area into 128x128 big sprites. (The TaitoZ system also used a similar sprite map system, but moved the sprite map from RAM to ROM.) Top Speed has twin 68K CPUs which communicate via $10000 bytes of shared ram. The first 68000 handles screen, palette and sprites, and the road. The second 68000 handles inputs/dips, and does data processing in shared ram to relieve CPUA. There is also a Z80, which takes over sound duties. Dumper's info (topspedu) ------------- Main CPUs: Dual 68000 Sound: YM2151, OKI M5205 Some of the custom Taito chips look like Rastan Hardware Comments: Note b14-06, and b14-07, are duplicated twice on this board for some type of hardware graphics reasons. (DG: that's because of the twin tilemap generator chips. Can someone confirm they are PC080SN's please...?) There is a weird chip that is probably a Microcontroller made by Sharp. Part number: b14-31 - Sharp LH763J-70 TODO Lists ========== (Want to verify 68000 clocks) I don't know about the MSM5205 playback frequency, I set it to 4kHz because otherwise the samples plays at the beginning of a game would play past the end. The samples are stopped by the Z80, they don't stop automatically. So, if they should play at a higher frequency, the Z80 should stop them sooner - which would mean a higher interrupt rate, therefore a higher YM2151 clock rate. I haven't found how the second MSM5205 ROM is selected (I haven't even found when samples from that ROM should be played) Many unknown writes from the Z80: c000, c400, c800, cc00, d000, d200, d400, d600, b400. Accel and brake bits work differently depending on cab DSW Mame cannot yet support this, so accel/brake are not hooked up sensibly when upright cabinet is selected. The 8 level brake and accel inputs for the cockpit version should be mapped to a pedal for analogue pedal control. (Warlock did this but his changes need remerging.) Minor black glitches on the road: these are all on the right hand edge of the tilemap making up the "left" half: this is the upper of the two road tilemaps so any gunk will be visible. 'Tearing' effect between the two road tilemaps is visible when single-stepping. A sync issue? *Loads* of complaints from the Taito sound system in the log. CPUA (on all variants) could have a spin_until_int at $63a. Motor CPU: appears to be identical to one in ChaseHQ. DIPs Raster line color control ------------------------- Used to make the road move. Each word controls one pixel row. 0x800000 - 0x1ff raster color control for one road tilemap 0x800200 - 0x3ff raster color control for the other Road tile colors are (all?) in the range 0x100-103. Top road section (tilemap at 0xa08000) uses 0x100 and 0x101. Bottom section (tilemap at 0xb00000) uses 0x102 and 0x103. This would allow colors on left and right side of road to be different. In practice it seems Taito didn't take advantage of this. Each tilemap is usually all one color value. Every now and then (10s or so) the value alternates. This seems to be determined by whether the current section of road has white lines in the middle. (0x101/3 gives white lines.) The raster line color control area has groups of four values which cascade down through it so the road colors cascade down the screen. There are three known groups (start is arbitrary; the cycles repeat ad infinitum or until a different cycle starts; values given are from bottom to top of screen): (i) White lines in center of road 12 %10010 1f %11111 00 %00000 0d %01101 (ii) No lines in center of road 08 %01000 0c %01100 1a %11010 1e %11110 (iii) Under bridge or in tunnel [note almost identical to (i)] ffe0 %00000 ffed %01101 fff2 %10010 ffef %01111 (iv) Unknown 4th group for tunnels in later parts of the game that have no white lines, analogous to (ii) ? Correlating with screenshots suggests that these bits refer to: x.... road body ? .x... lines in road center and inner edge ..x.. lines at road outer edge ...x. outside road ? ....x ??? Actual gfx tiles used for the road only use colors 1-5. Palette offsets: (0 = transparency) 1 = lines in road center 2 = road edge (inner) 3 = road edge (outer) 4 = road body 5 = outside road Each palette block contains three possible sets of 5 colors. Entries 1-5 (standard), 6-10 (alternate), 11-15 (tunnels). In tunnels only 11-15 are used. Outside tunnels there is a choice between the standard colors and the alternate colors. The road body could in theory take a standard color while 'outside the road' took on an alternate. But in practice the game is using a very limited choice of raster control words, so we don't know. Need to test whether sections of the road with unknown raster control words (tunnels late in the game without central white lines) are correct against a real machine. Also are the 'prelines' shortly before white road lines appear correct? CHECK screen inits at $1692 These suggest that rowscroll areas are all 0x1000 long and there are TWO for each tilemap layer. 256 rows => 256 words => 0x200 bytes. So probably the inits are far too long. Maybe the second area for each layer contains colscroll ? Stephh's notes (based on the game M68000 code and some tests) : 1) 'topspeed' and 'topspedu' - All addresses are for 2nd M68000 CPU ! - Region stored at 0x01fffe.w - Sets : * 'topspeed' : region = 0x0003 * 'topspedu' : region = 0x0004 - Coinage relies on the region (code at 0x00dd10) : * 0x0001 (Japan), 0x0002 (US) and 0x0004 (US, Romstar license) use TAITO_COINAGE_JAPAN_OLD * 0x0003 (World) uses TAITO_COINAGE_WORLD - Notice screen only if region = 0x0001 - Game name : "Top Speed" - It's only possible to continue a game when you reach at least level 2 - The "Continue Price" Dip Switch is a bit weird when set to 1C_1C : * coin 1 : 1C_1C (normal behaviour) * coin 2 : same number of credits as per Coin B settings, but twice coins for example, when Coin B setting is 1C_2C, when pressing COIN2, you'll get 2 credits, but you'll be able to continue 4 times before needing to insert another coin - There is sort of built-in cheat (code at 0x015332) : * set "Allow Continue" Dip Switch to "No" * set "Continue Price" Dip Switch to 1C_1C * set contents of 0x000402.b to 0x55 (be aware that this address is in ROM area) * you'll then be awarded infinite time :) 2) 'fullthrl' - All addresses are for 2nd M68000 CPU ! - Region stored at 0x01fffe.w - Sets : * 'fullthrl' : region = 0x0001 - Game name : "Full Throttle" - Same other notes as for 'topspeed' ***************************************************************************/ #include "emu.h" #include "cpu/z80/z80.h" #include "includes/taitoipt.h" #include "cpu/m68000/m68000.h" #include "video/taitoic.h" #include "machine/taitoio.h" #include "audio/taitosnd.h" #include "sound/2151intf.h" #include "sound/msm5205.h" #include "includes/topspeed.h" #include "topspeed.lh" static READ16_HANDLER( sharedram_r ) { topspeed_state *state = space->machine().driver_data(); return state->m_sharedram[offset]; } static WRITE16_HANDLER( sharedram_w ) { topspeed_state *state = space->machine().driver_data(); COMBINE_DATA(&state->m_sharedram[offset]); } static void parse_control( running_machine &machine ) /* assumes Z80 sandwiched between 68Ks */ { /* bit 0 enables cpu B */ /* however this fails when recovering from a save state if cpu B is disabled !! */ topspeed_state *state = machine.driver_data(); device_set_input_line(state->m_subcpu, INPUT_LINE_RESET, (state->m_cpua_ctrl &0x1) ?
