/*************************************************************************** Atari Tunnel Hunt hardware Games supported: * Tunnel Hunt Known issues: * see below **************************************************************************** MAME driver for Tunnel Hunt (C)1981 (aka Tube Chase) Developed by Atari Hardware by Dave Sherman Game Programmed by Owen Rubin Licensed and Distributed by Centuri Many thanks to Owen Rubin for invaluable hardware information and game description! Known Issues: Coin Input seems unresponsive. Colors: - Hues are hardcoded. There doesn't appear to be any logical way to map the color proms so that the correct colors appear. See last page of schematics for details. Are color proms bad? (shouldn't be, both sets were the same) Alphanumeric Layer: - placement for some characters seems strange (but may well be correct). Shell Objects: - vstretch/placement/color handling isn't confirmed - two bitplanes per character or two banks? Motion Object: - enemy ships look funny when they get close (to ram player) - stretch probably isn't implemented correctly (see splash screen with zooming "TUNNEL HUNT" logo. - colors may not be mapped correctly. Square Generator: - needs optimization ***************************************************************************/ #include "driver.h" #include "sound/pokey.h" UINT8 *tunhunt_ram; extern WRITE8_HANDLER( tunhunt_videoram_w ); extern WRITE8_HANDLER( tunhunt_mott_w ); extern PALETTE_INIT( tunhunt ); extern VIDEO_START( tunhunt ); extern VIDEO_UPDATE( tunhunt ); /************************************* * * Output ports * *************************************/ UINT8 tunhunt_control; static WRITE8_HANDLER( tunhunt_control_w ) { /* 0x01 coin counter#2 "right counter" 0x02 coin counter#1 "center counter" 0x04 "left counter" 0x08 cover screen (shell0 hstretch) 0x10 cover screen (shell1 hstretch) 0x40 start LED 0x80 in-game */ tunhunt_control = data; coin_counter_w( 0,data&0x01 ); coin_counter_w( 1,data&0x02 ); set_led_status( 0, data&0x40 ); /* start */ } /************************************* * * Input ports * *************************************/ static READ8_HANDLER( tunhunt_button_r ) { int data = readinputportbytag("IN0"); return ((data>>offset)&1)?0x00:0x80; } static READ8_HANDLER( dsw1_r ) { return readinputportbytag("DSW")&0xff; } static READ8_HANDLER( dsw2_0r ) { return (readinputportbytag("DSW")&0x0100)?0x80:0x00; } static READ8_HANDLER( dsw2_1r ) { return (readinputportbytag("DSW")&0x0200)?0x80:0x00; } static READ8_HANDLER( dsw2_2r ) { return (readinputportbytag("DSW")&0x0400)?0x80:0x00; } static READ8_HANDLER( dsw2_3r ) { return (readinputportbytag("DSW")&0x0800)?0x80:0x00; } static READ8_HANDLER( dsw2_4r ) { return (readinputportbytag("DSW")&0x1000)?0x80:0x00; } /************************************* * * Main CPU memory handlers * *************************************/ static ADDRESS_MAP_START( readmem, ADDRESS_SPACE_PROGRAM, 8 ) AM_RANGE(0x0000, 0x03ff) AM_READ(MRA8_RAM) /* Work RAM */ AM_RANGE(0x2000, 0x2007) AM_READ(tunhunt_button_r) AM_RANGE(0x3000, 0x300f) AM_READ(pokey1_r) AM_RANGE(0x4000, 0x400f) AM_READ(pokey2_r) AM_RANGE(0x5000, 0x7fff) AM_READ(MRA8_ROM) AM_RANGE(0xfffa, 0xffff) AM_READ(MRA8_ROM) ADDRESS_MAP_END static ADDRESS_MAP_START( writemem, ADDRESS_SPACE_PROGRAM, 8 ) AM_RANGE(0x0000, 0x03ff) AM_WRITE(MWA8_RAM) AM_BASE(&tunhunt_ram) /* Work RAM */ AM_RANGE(0x1080, 0x10ff) AM_WRITE(MWA8_RAM) AM_RANGE(0x1200, 0x12ff) AM_WRITE(MWA8_RAM) AM_RANGE(0x1400, 0x14ff) AM_WRITE(MWA8_RAM) AM_RANGE(0x1600, 0x160f) AM_WRITE(MWA8_RAM) AM_BASE(&paletteram) /* COLRAM (D7-D4 SHADE; D3-D0 COLOR) */ AM_RANGE(0x1800, 0x1800) AM_WRITE(MWA8_RAM) /* SHEL0H */ AM_RANGE(0x1a00, 0x1a00) AM_WRITE(MWA8_RAM) /* SHEL1H */ AM_RANGE(0x1c00, 0x1c00) AM_WRITE(MWA8_RAM) /* MOBJV */ AM_RANGE(0x1e00, 0x1eff) AM_WRITE(tunhunt_videoram_w) AM_BASE(&videoram) /* ALPHA */ AM_RANGE(0x2c00, 0x2fff) AM_WRITE(tunhunt_mott_w) AM_BASE(&spriteram) AM_RANGE(0x2000, 0x2000) AM_WRITE(MWA8_NOP) /* watchdog */ AM_RANGE(0x2400, 0x2400) AM_WRITE(MWA8_NOP) /* INT ACK */ AM_RANGE(0x2800, 0x2800) AM_WRITE(tunhunt_control_w) AM_RANGE(0x3000, 0x300f) AM_WRITE(pokey1_w) AM_RANGE(0x4000, 0x400f) AM_WRITE(pokey2_w) AM_RANGE(0x5000, 0xffff) AM_WRITE(MWA8_ROM) ADDRESS_MAP_END /************************************* * * Port definitions * *************************************/ static INPUT_PORTS_START( tunhunt ) PORT_START_TAG("IN0") PORT_BIT ( 0x01, IP_ACTIVE_HIGH, IPT_TILT ) PORT_BIT ( 0x02, IP_ACTIVE_HIGH, IPT_BUTTON1 ) PORT_DIPNAME( 0x04, 0x00, DEF_STR( Service_Mode ) ) PORT_DIPSETTING ( 0x00, DEF_STR( Off ) ) PORT_DIPSETTING ( 0x04, DEF_STR( On ) ) //Should the above switch be described as: //PORT_SERVICE(0x04, IP_ACTIVE_HIGH) ?
