Collision detection does work, but there are bits which define the type of collision (and determine whether a pit stop is required) that I don't know how to handle. - sound: missing engine noise - "radar" is probably wrong - LED and tachometer display are missing/faked Note that a dipswitch setting allows score to be displayed onscreen, but there's no equivalent for tachometer. - TODO: the two sound callbacks could, under unusual circumstances, conflict with one another, causing the newly written value to have its bit 7 cleared before the sound cpu reads it. The proper way to handle this is to use a single callback which processes a timestamped event queue. - TODO: merge the sound system with taitosj.cpp, as the sound system is almost completely identical. Also import the taitosj.cpp dac/volume system, as the system used in audio/grchamp.cpp for dac output is incorrect. Notes: - The object of the game is to avoid the opposing cars. - The player has to drive through Dark Tunnels, Rain, Lightning, Sleet, Snow, and a Track that suddenly divides to get to the Finish Line first. - "GRAND CHAMPION" has a Radar Feature which enables the Player to see his position relative to the other cars. - A Rank Feature is also provided which shows the Player's numerical rank all through the race. - The Speech Feature enhances the game play. - Schematics: https://ia800501.us.archive.org/16/items/ArcadeGameManualGrandchampion/grandchampion.pdf ***************************************************************************/ #include "emu.h" #include "includes/grchamp.h" #include "cpu/z80/z80.h" #include "sound/ay8910.h" #include "speaker.h" #include "grchamp.lh" /************************************* * * Constants * *************************************/ #define MASTER_CLOCK (18432000) #define SOUND_CLOCK (6000000) #define PIXEL_CLOCK (MASTER_CLOCK/3) #define HTOTAL (384) #define HBEND (0) #define HBSTART (256) #define VTOTAL (264) #define VBEND (16) #define VBSTART (240) /************************************* * * Machine setup * *************************************/ void grchamp_state::machine_start() { m_digits.resolve(); m_soundlatch_data = 0x00; m_soundlatch_flag = false; save_item(NAME(m_cpu0_out)); save_item(NAME(m_cpu1_out)); save_item(NAME(m_comm_latch)); save_item(NAME(m_comm_latch2)); save_item(NAME(m_ledlatch)); save_item(NAME(m_ledaddr)); save_item(NAME(m_ledram)); save_item(NAME(m_collide)); save_item(NAME(m_collmode)); } void grchamp_state::machine_reset() { m_soundnmi->in_w<0>(0); // disable sound nmi /* if the coin system is 1 way, lock Coin B (Page 40) */ machine().bookkeeping().coin_lockout_w(1, (ioport("DSWB")->read() & 0x10) ?
