(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 adresses 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 licence) 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 adress is in ROM area) + * you'll then be awarded infinite time :) + + +2) 'fullthrl' + + - All adresses 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 "driver.h" +#include "taitoipt.h" +#include "cpu/m68000/m68000.h" +#include "video/taitoic.h" +#include "audio/taitosnd.h" +#include "sound/2151intf.h" +#include "sound/msm5205.h" + +WRITE16_HANDLER( rainbow_spritectrl_w ); +WRITE16_HANDLER( rastan_spriteflip_w ); + +VIDEO_START( topspeed ); +VIDEO_UPDATE( topspeed ); + +static UINT16 cpua_ctrl = 0xff; +static INT32 ioc220_port = 0; + +extern UINT16 *topspeed_spritemap; + +static size_t sharedram_size; +static UINT16 *sharedram; + +extern UINT16 *topspeed_raster_ctrl; + + +static READ16_HANDLER( sharedram_r ) +{ + return sharedram[offset]; +} + +static WRITE16_HANDLER( sharedram_w ) +{ + COMBINE_DATA(&sharedram[offset]); +} + +static void parse_control(void) /* assumes Z80 sandwiched between 68Ks */ +{ + /* bit 0 enables cpu B */ + /* however this fails when recovering from a save state + if cpu B is disabled !! */ + cpunum_set_input_line(2, INPUT_LINE_RESET, (cpua_ctrl &0x1) ?
