14
15 Top Speed / Full Throttle is the forerunner of the Taito Z system on
16 which Taito's driving games were based from 1988-91. (You can spot some
17 similarities with Continental Circus, the first of the TaitoZ games.)
18
19 The game hardware has 5 separate layers of graphics - four 64x64 tiled
20 scrolling background planes of 8x8 tiles (two of which are used for
21 drawing the road), and a sprite plane.
22
23 Taito got round the limitations of the tilemap generator they were using
24 (which only supports two layers) by using a pair of them.
25
26 [Trivia: Taito employed the same trick three years later, this time with
27 the TC0100SCN in "Thunderfox".]
28
29 Top Speed's sprites are 16x8 tiles aggregated through a RAM sprite map
30 area into 128x128 big sprites. (The TaitoZ system also used a similar
31 sprite map system, but moved the sprite map from RAM to ROM.)
32
33 Top Speed has twin 68K CPUs which communicate via $10000 bytes of
34 shared ram. The first 68000 handles screen, palette and sprites, and
35 the road. The second 68000 handles inputs/dips, and does data processing
36 in shared ram to relieve CPUA. There is also a Z80, which takes over
37 sound duties.

41 -------------
42
43 Main CPUs: Dual 68000
44 Sound: YM2151, OKI M5205
45
46 Some of the custom Taito chips look like Rastan Hardware
47
48 Comments: Note b14-06, and b14-07, are duplicated twice on this board
49 for some type of hardware graphics reasons. (DG: that's because of
50 the twin tilemap generator chips. Can someone confirm they are
51 PC080SN's please...?)
52
53 There is a weird chip that is probably a Microcontroller made by Sharp.
54 Part number: b14-31 - Sharp LH763J-70

57 TODO Lists
58 ==========
59
60 (Want to verify 68000 clocks)
61
62 Accel and brake bits work differently depending on cab DSW
63 Mame cannot yet support this, so accel/brake are not hooked up
64 sensibly when upright cabinet is selected.
65
66 The 8 level brake and accel inputs for the cockpit version
67 should be mapped to a pedal for analogue pedal control.
68 (Warlock did this but his changes need remerging.)
69
70 Minor black glitches on the road: these are all on the right
71 hand edge of the tilemap making up the "left" half: this is
72 the upper of the two road tilemaps so any gunk will be visible.
73
74 'Tearing' effect between the two road tilemaps is visible when
75 single-stepping. A sync issue?
76
77 *Loads* of complaints from the Taito sound system in the log.
78
79 CPUA (on all variants) could have a spin_until_int at $63a.
80
81 Motor CPU: appears to be identical to one in ChaseHQ.
82
83 DIPs
84
85
86 Raster line color control
87 -------------------------
88
89 Used to make the road move. Each word controls one pixel row.
90
91 0x800000 - 0x1ff raster color control for one road tilemap
92 0x800200 - 0x3ff raster color control for the other
93
94 Road tile colors are (all?) in the range 0x100-103. Top road section
95 (tilemap at 0xa08000) uses 0x100 and 0x101. Bottom section
96 (tilemap at 0xb00000) uses 0x102 and 0x103. This would allow colors
97 on left and right side of road to be different. In practice it seems
98 Taito didn't take advantage of this.
99
100 Each tilemap is usually all one color value. Every now and then (10s
101 or so) the value alternates. This seems to be determined by whether
102 the current section of road has white lines in the middle. (0x101/3
103 gives white lines.)
104
105 The raster line color control area has groups of four values which
106 cascade down through it so the road colors cascade down the screen.
107
108 There are three known groups (start is arbitrary; the cycles repeat ad
109 infinitum or until a different cycle starts; values given are from bottom
110 to top of screen):
111
112 (i) White lines in center of road
113
114 12 %10010
115 1f %11111
116 00 %00000
117 0d %01101
118
119 (ii) No lines in center of road
120
121 08 %01000
122 0c %01100
123 1a %11010
124 1e %11110
125
126 (iii) Under bridge or in tunnel [note almost identical to (i)]
127
128 ffe0 %00000
129 ffed %01101
130 fff2 %10010
131 ffef %01111
132
133 (iv) Unknown 4th group for tunnels in later parts of the game that have
134 no white lines, analogous to (ii) ?
135
136
137 Correlating with screenshots suggests that these bits refer to:
138
139 x.... road body ?
140 .x... lines in road center and inner edge
141 ..x.. lines at road outer edge
142 ...x. outside road ?
143 ....x ???
144
145
146 Actual gfx tiles used for the road only use colors 1-5. Palette offsets:
147
148 (0 = transparency)
149 1 = lines in road center
150 2 = road edge (inner)
151 3 = road edge (outer)
152 4 = road body
153 5 = outside road
154
155 Each palette block contains three possible sets of 5 colors. Entries 1-5
156 (standard), 6-10 (alternate), 11-15 (tunnels).
157
158 In tunnels only 11-15 are used. Outside tunnels there is a choice between
159 the standard colors and the alternate colors. The road body could in theory
160 take a standard color while 'outside the road' took on an alternate. But
161 in practice the game is using a very limited choice of raster control words,
162 so we don't know.
163
164 Need to test whether sections of the road with unknown raster control words
165 (tunnels late in the game without central white lines) are correct against
166 a real machine.
167
168 Also are the 'prelines' shortly before white road lines appear correct?
169
170
171
172 CHECK screen inits at $1692
173
174 These suggest that rowscroll areas are all 0x1000 long and there are TWO
175 for each tilemap layer.
176
177 256 rows => 256 words => 0x200 bytes. So probably the inits are far too long.
178
179 Maybe the second area for each layer contains colscroll ?
