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

43 PCB contents (from CPU PCB photo)
44 -------------
45
46 XTAL: 16000.00KHZ and 26686.00KHZ
47 CPU: 2 * 68000-8, Z80 + Z80 CTC
48 Sound: YM2151, YM3012(DAC), 2 * OKI M5205
49 Taito: 2 * PC080SN, PC060HA, TC0040IOC, 2 * TC0060DCA, PC050CM

53 TODO Lists
54 ==========
55
56 Minor black glitches on the road: these are all on the right
57 hand edge of the tilemap making up the "left" half: this is
58 the upper of the two road tilemaps so any gunk will be visible.
59
60 'Tearing' effect between the two road tilemaps is visible when
61 single-stepping. A sync issue?
62
63 CPUA (on all variants) could have a spin_until_int at $63a.
64
65 Motor CPU: appears to be identical to one in ChaseHQ.
66
67
68 Stephh's notes (based on the game M68000 code and some tests) :
69
70 1) 'topspeed' and 'topspedu'
71
72 - All addresses are for 2nd M68000 CPU !
73 - Region stored at 0x01fffe.w
74 - Sets :
75 * 'topspeed' : region = 0x0003
76 * 'topspedu' : region = 0x0004
77 - Coinage relies on the region (code at 0x00dd10) :
78 * 0x0001 (Japan), 0x0002 (US) and 0x0004 (US, Romstar license) use TAITO_COINAGE_JAPAN_OLD
79 * 0x0003 (World) uses TAITO_COINAGE_WORLD
80 - Notice screen only if region = 0x0001
81 - Game name : "Top Speed"
82 - It's only possible to continue a game when you reach at least level 2
83 - The "Continue Price" Dip Switch is a bit weird when set to 1C_1C :
84 * coin 1 : 1C_1C (normal behaviour)
85 * coin 2 : same number of credits as per Coin B settings, but twice coins
86 for example, when Coin B setting is 1C_2C, when pressing COIN2,
87 you'll get 2 credits, but you'll be able to continue 4 times
88 before needing to insert another coin
89 - There is sort of built-in cheat (code at 0x015332) :
90 * set "Allow Continue" Dip Switch to "No"
91 * set "Continue Price" Dip Switch to 1C_1C
92 * set contents of 0x000402.b to 0x55 (be aware that this address is in ROM area)
93 * you'll then be awarded infinite time :)
94
95
96 2) 'fullthrl'
97
98 - All addresses are for 2nd M68000 CPU !
99 - Region stored at 0x01fffe.w
100 - Sets :
101 * 'fullthrl' : region = 0x0001
102 - Game name : "Full Throttle"
103 - Same other notes as for 'topspeed'
