Demonstration-Freeze Mode: - Just like Demonstration Mode, but with frozen screen action. Both Demonstration Modes: - Pressing RESET in either mode will cause the game to lock up. To recover, set switch 1 to On. - You can start at any level from 1..81, so it's an easy way of seeing what the game can throw at you - The score is zeroed at the end of the game, so you also don't have to worry about artificially high scores disrupting your scoring records as stored in the game's EAROM. Easy Difficulty: - Enemies move more slowly - One less enemy shot on the screen at any given time Hard Difficulty: - Enemies move more quickly - 1-4 more enemy shots on the screen at any given time - One more enemy may be on the screen at any given time High Scores: - Changing toggles 1-5 at L12 (more/fewer lives, bonus ship levels) will erase the high score table. - You should also wait 8-10 seconds after a game has been played before entering self-test mode or powering down; otherwise, you might erase or corrupt the high score table. ***************************************************************************/ #include "driver.h" #include "vidhrdw/generic.h" #include "machine/mathbox.h" #include "vidhrdw/vector.h" extern int tempest_IN0_r(int offset); extern int tempest_IN3_r(int offset); extern int tempest_interrupt(void); extern int tempest_spinner(int); extern int bzone_vh_start(void); extern void bzone_vh_stop(void); extern void bzone_vh_screenrefresh(struct osd_bitmap *bitmap); extern void bzone_vh_init_colors(unsigned char *palette, unsigned char *colortable, const unsigned char *color_prom); extern int bzone_rand_r(int offset); extern void milliped_pokey1_w(int offset,int data); extern void milliped_pokey2_w(int offset,int data); extern int milliped_sh_start(void); extern void milliped_sh_stop(void); extern void milliped_sh_update(void); static struct MemoryReadAddress readmem[] = { { 0x0000, 0x07ff, MRA_RAM }, { 0x9000, 0xdfff, MRA_ROM }, { 0x3000, 0x3fff, MRA_ROM }, { 0xf800, 0xffff, MRA_ROM }, /* for the reset / interrupt vectors */ { 0x2000, 0x2fff, MRA_RAM, &vectorram }, { 0x0c00, 0x0c00, tempest_IN0_r }, /* IN0 */ { 0x0d00, 0x0d00, input_port_1_r }, /* DSW1 */ { 0x0e00, 0x0e00, input_port_2_r }, /* DSW2 */ { 0x60c8, 0x60c8, tempest_IN3_r }, /* IN3 */ { 0x60d8, 0x60d8, input_port_4_r }, /* IN4 */ { 0x6040, 0x6040, mb_status_r }, { 0x6060, 0x6060, mb_lo_r }, { 0x6070, 0x6070, mb_hi_r }, { 0x60ca, 0x60ca, bzone_rand_r }, { 0x60da, 0x60da, bzone_rand_r }, { -1 } /* end of table */ }; static struct MemoryWriteAddress writemem[] = { { 0x0000, 0x07ff, MWA_RAM }, { 0x0800, 0x080f, MWA_RAM, &colorram }, { 0x2000, 0x2fff, MWA_RAM, &vectorram }, { 0x60c0, 0x60cf, milliped_pokey1_w }, { 0x60d0, 0x60df, milliped_pokey2_w }, { 0x6080, 0x609f, mb_go }, { 0x4800, 0x4800, vg_go }, { 0x5000, 0x5000, MWA_RAM }, { 0x5800, 0x5800, vg_reset }, { 0x9000, 0xdfff, MWA_ROM }, { 0x3000, 0x3fff, MWA_ROM }, { -1 } /* end of table */ }; static struct InputPort input_ports[] = { { /* IN0 */ 0xff, { OSD_KEY_3, OSD_KEY_4, 0, OSD_KEY_F1, OSD_KEY_F2, 0, 0, 0 }, { 0, 0, 0, 0, 0, 0, 0, 0 } }, { /* DSW1 */ 0x00, { 0, 0, 0, 0, 0, 0, 0, 0 }, { 0, 0, 0, 0, 0, 0, 0, 0 } }, { /* DSW2 */ 0x00, { 0, 0, 0, 0, 0, 0, 0, 0 }, { 0, 0, 0, 0, 0, 0, 0, 0 } }, { /* IN2/DSW3 */ 0x00, { OSD_KEY_LEFT, OSD_KEY_RIGHT, 0, 0, 0, 0, 0, 0 }, { OSD_JOY_LEFT, OSD_JOY_RIGHT, 0, 0, 0, 0, 0, 0 } }, { /* IN4 */ 0x03, { 0, 0, 0, OSD_KEY_ALT, OSD_KEY_CONTROL, OSD_KEY_1, OSD_KEY_2, 0 }, { 0, 0, 0, OSD_JOY_FIRE2, OSD_JOY_FIRE1, 0, 0, 0 } }, { -1 } }; static struct TrakPort trak_ports[] = { { X_AXIS, 1, 1.0, tempest_spinner }, { -1 } }; static struct KEYSet keys[] = { { 3, 0, "TURN CLOCKWISE" }, { 3, 1, "TURN ANTICLOCKWISE" }, { 4, 4, "FIRE" }, { 4, 3, "SUPER ZAPPER" }, { -1 } }; static struct DSW dsw[] = { { 2, 0x38, "BONUS EVERY", { "20000", "10000", "30000", "40000", "50000", "60000", "70000", "NONE" } }, { 2, 0x06, "LANGUAGE", { "ENGLISH", "FRENCH", "GERMAN", "SPANISH" } }, { 4, 0x01, "MINIUM RATING", { "1/3/5/7/9", "TIED TO HIGHSCORE" } }, { 4, 0x06, "DIFFICULTY", { "MEDIUM", "EASY", "HARD", "MEDIUM" } }, { -1 } }; static struct GfxDecodeInfo gfxdecodeinfo[] = { { -1 } /* end of array */ }; static unsigned char color_prom[] = { 0x02,0x02,0x02, /* WHITE */ 0x02,0x02,0x00, /* YELLOW */ 0x02,0x00,0x02, /* MAGENTA */ 0x02,0x00,0x00, /* RED */ 0x00,0x02,0x02, /* CYAN */ 0x00,0x02,0x00, /* GREEN */ 0x00,0x00,0x02, /* BLUE */ 0x00,0x00,0x00, /* BLACK */ }; static struct MachineDriver machine_driver = { /* basic machine hardware */ { { CPU_M6502, 1500000, /* 1.5 Mhz */ 0, readmem,writemem,0,0, tempest_interrupt,4 /* 4 interrupts per frame?
