/********************************************************************************* Zero Zone memory map driver by Brad Oliver CPU 1 : 68000, uses irq 1 0x000000 - 0x01ffff : ROM 0x080000 - 0x08000f : input ports and dipswitches 0x088000 - 0x0881ff : palette RAM, 256 total colors 0x09ce00 - 0x09d9ff : video ram, 48x32 0x0c0000 - 0x0cffff : RAM 0x0f8000 - 0x0f87ff : RAM (unused?) Stephh's notes : IMO, the game only has 2 buttons (1 to rotate the pieces and 1 for help). The 3rd button (when the Dip Switch is activated) subs one "line" (0x0c0966 for player 1 and 0x0c1082 for player 2) each time it is pressed. As I don't see why such thing would REALLY exist, I've added the IPF_CHEAT flag for the Dip Switch and the 3rd button of each player. TODO: * adpcm samples don't seem to be playing at the proper tempo - too fast? *********************************************************************************/ #include "emu.h" #include "includes/zerozone.h" #include "cpu/z80/z80.h" #include "cpu/m68000/m68000.h" #include "sound/okim6295.h" WRITE16_MEMBER( zerozone_state::sound_w ) { if (ACCESSING_BITS_8_15) { soundlatch_byte_w(space, offset, data >> 8); m_audiocpu->set_input_line_and_vector(0, HOLD_LINE, 0xff); } } static ADDRESS_MAP_START( main_map, AS_PROGRAM, 16, zerozone_state ) AM_RANGE(0x000000, 0x01ffff) AM_ROM AM_RANGE(0x080000, 0x080001) AM_READ_PORT("SYSTEM") AM_RANGE(0x080002, 0x080003) AM_READ_PORT("INPUTS") AM_RANGE(0x080008, 0x080009) AM_READ_PORT("DSWB") AM_RANGE(0x08000a, 0x08000b) AM_READ_PORT("DSWA") AM_RANGE(0x084000, 0x084001) AM_WRITE(sound_w) AM_RANGE(0x088000, 0x0881ff) AM_RAM_WRITE(paletteram_RRRRGGGGBBBBRGBx_word_w) AM_SHARE("paletteram") AM_RANGE(0x098000, 0x098001) AM_RAM /* Watchdog? */ AM_RANGE(0x09ce00, 0x09ffff) AM_RAM_WRITE(tilemap_w) AM_SHARE("videoram") AM_RANGE(0x0b4000, 0x0b4001) AM_WRITE(tilebank_w) AM_RANGE(0x0c0000, 0x0cffff) AM_RAM AM_RANGE(0x0f8000, 0x0f87ff) AM_RAM /* Never read from */ ADDRESS_MAP_END static ADDRESS_MAP_START( sound_map, AS_PROGRAM, 8, zerozone_state ) AM_RANGE(0x0000, 0x7fff) AM_ROM AM_RANGE(0x8000, 0x87ff) AM_RAM AM_RANGE(0x9800, 0x9800) AM_DEVREADWRITE("oki", okim6295_device, read, write) AM_RANGE(0xa000, 0xa000) AM_READ(soundlatch_byte_r) ADDRESS_MAP_END static INPUT_PORTS_START( zerozone ) PORT_START("SYSTEM") PORT_BIT( 0x0001, IP_ACTIVE_LOW, IPT_COIN1 ) PORT_BIT( 0x0002, IP_ACTIVE_LOW, IPT_COIN2 ) PORT_BIT( 0x0004, IP_ACTIVE_LOW, IPT_UNKNOWN ) PORT_BIT( 0x0008, IP_ACTIVE_LOW, IPT_START1 ) PORT_BIT( 0x0010, IP_ACTIVE_LOW, IPT_START2 ) PORT_BIT( 0x0020, IP_ACTIVE_LOW, IPT_UNKNOWN ) PORT_BIT( 0x0040, IP_ACTIVE_LOW, IPT_UNKNOWN ) PORT_BIT( 0x0080, IP_ACTIVE_LOW, IPT_UNKNOWN ) PORT_START("INPUTS") PORT_BIT( 0x0001, IP_ACTIVE_LOW, IPT_JOYSTICK_RIGHT ) PORT_4WAY PORT_PLAYER(1) PORT_BIT( 0x0002, IP_ACTIVE_LOW, IPT_JOYSTICK_LEFT ) PORT_4WAY PORT_PLAYER(1) PORT_BIT( 0x0004, IP_ACTIVE_LOW, IPT_JOYSTICK_DOWN ) PORT_4WAY PORT_PLAYER(1) PORT_BIT( 0x0008, IP_ACTIVE_LOW, IPT_JOYSTICK_UP ) PORT_4WAY PORT_PLAYER(1) PORT_BIT( 0x0010, IP_ACTIVE_LOW, IPT_BUTTON1 ) PORT_PLAYER(1) PORT_BIT( 0x0020, IP_ACTIVE_LOW, IPT_BUTTON2 ) PORT_PLAYER(1) PORT_BIT( 0x0040, IP_ACTIVE_LOW, IPT_BUTTON3 ) PORT_PLAYER(1) PORT_NAME("P1 Score Line (Cheat)") PORT_BIT( 0x0080, IP_ACTIVE_LOW, IPT_UNKNOWN ) PORT_BIT( 0x0100, IP_ACTIVE_LOW, IPT_JOYSTICK_RIGHT ) PORT_4WAY PORT_PLAYER(2) PORT_BIT( 0x0200, IP_ACTIVE_LOW, IPT_JOYSTICK_LEFT ) PORT_4WAY PORT_PLAYER(2) PORT_BIT( 0x0400, IP_ACTIVE_LOW, IPT_JOYSTICK_DOWN ) PORT_4WAY PORT_PLAYER(2) PORT_BIT( 0x0800, IP_ACTIVE_LOW, IPT_JOYSTICK_UP ) PORT_4WAY PORT_PLAYER(2) PORT_BIT( 0x1000, IP_ACTIVE_LOW, IPT_BUTTON1 ) PORT_PLAYER(2) PORT_BIT( 0x2000, IP_ACTIVE_LOW, IPT_BUTTON2 ) PORT_PLAYER(2) PORT_BIT( 0x4000, IP_ACTIVE_LOW, IPT_BUTTON3 ) PORT_PLAYER(2) PORT_NAME("P2 Score Line (Cheat)") PORT_BIT( 0x8000, IP_ACTIVE_LOW, IPT_UNKNOWN ) PORT_START("DSWA") PORT_DIPNAME( 0x0007, 0x0007, DEF_STR( Coinage ) ) PORT_DIPSETTING( 0x0000, DEF_STR( 5C_1C ) ) PORT_DIPSETTING( 0x0001, DEF_STR( 4C_1C ) ) PORT_DIPSETTING( 0x0002, DEF_STR( 3C_1C ) ) PORT_DIPSETTING( 0x0003, DEF_STR( 2C_1C ) ) PORT_DIPSETTING( 0x0007, DEF_STR( 1C_1C ) ) PORT_DIPSETTING( 0x0006, DEF_STR( 1C_2C ) ) PORT_DIPSETTING( 0x0005, DEF_STR( 1C_3C ) ) PORT_DIPSETTING( 0x0004, DEF_STR( 1C_4C ) ) PORT_DIPNAME( 0x0008, 0x0008, DEF_STR( Difficulty ) ) PORT_DIPSETTING( 0x0008, "In Game Default" ) // 130, 162 or 255 "lines" PORT_DIPSETTING( 0x0000, "Always Hard" ) // 255 "lines" PORT_DIPNAME( 0x0010, 0x0010, "Speed" ) PORT_DIPSETTING( 0x0010, DEF_STR( Normal ) ) // Drop every 20 frames PORT_DIPSETTING( 0x0000, "Fast" ) // Drop every 18 frames PORT_DIPNAME( 0x0020, 0x0020, DEF_STR( Demo_Sounds ) ) PORT_DIPSETTING( 0x0000, DEF_STR( Off ) ) PORT_DIPSETTING( 0x0020, DEF_STR( On ) ) PORT_DIPUNUSED( 0x0040, IP_ACTIVE_LOW ) PORT_DIPUNUSED( 0x0080, IP_ACTIVE_LOW ) PORT_START("DSWB") PORT_DIPUNUSED( 0x0100, IP_ACTIVE_LOW ) PORT_DIPUNUSED( 0x0200, IP_ACTIVE_LOW ) PORT_DIPNAME( 0x0400, 0x0400, "Helps" ) PORT_DIPSETTING( 0x0400, "1" ) PORT_DIPSETTING( 0x0000, "2" ) PORT_DIPNAME( 0x0800, 0x0800, "Bonus Help" ) PORT_DIPSETTING( 0x0000, "30000" ) PORT_DIPSETTING( 0x0800, DEF_STR( None ) ) PORT_DIPNAME( 0x1000, 0x1000, "Activate 'Score Line'?
