/***************************************************************************** Reactor hardware: very similar to Q*bert with a different memory map... Thanks to Richard Davies who provided a keyboard/joystick substitute for the trackball (now, who wants to add mouse services in Mame ?-) Main processor (8088 minimum mode) memory map. 0000-1fff RAM 2000-2fff sprite programmation (64 sprites) 3000-37ff background ram (32x30 chars) 4000-4fff background object ram 6000-67ff palette ram (palette of 16 colors) 7000-77ff i/o ports (see below) 8000-ffff ROM (reactor's prog) memory mapped ports: read: 7000 Dip switch 7001 Inputs 10-17 7002 trackball Horiz. input: -127 (left fastest) to +127 (right fastest), 0=stop 7003 trackball Vert. input: -127 (up fastest) to +127 (down fastest), 0=stop 7004 Inputs 40-47 write: 7000 watchdog timer clear 7001 trackball output (optional) 7002 Outputs 20-27 7003 Flipflop outputs: b7: F/B priority b6: horiz. flipflop b5: vert. flipflop b4: Output 33 b3: coin meter b2: knocker b1: coin 1 b0: coin lockout 7004 Outputs 40-47 interrupts: INTR not connected NMI connected to vertical blank Sound processor (6502) memory map: 0000-0fff RIOT (6532) 1000-1fff amplitude DAC 2000-2fff SC01 voice chip 3000-3fff voice clock DAC 4000-4fff socket expansion 5000-5fff socket expansion 6000-6fff socket expansion 7000-7fff PROM (repeated in 8000-ffff, A15 only used in socket expansion) Nota: I've used my own 6502 emulator in order to compute the digital effects because the clock emulation is much more precise and allows to put timestamps on amplitude DAC writes. MAME doesn't allow to compute the digital effects in real time like Euphoric (oops, ) so the effects are provided as precomputed samples (some of them are quite big, I should convert them to 22kHz) ******************************************************************************/ #include "driver.h" #include "vidhrdw/generic.h" extern int reactor_vh_start(void); extern void gottlieb_vh_init_basic_color_palette(unsigned char *palette, unsigned char *colortable,const unsigned char *color_prom); extern void gottlieb_sh_w(int offset, int data); extern void gottlieb_characterram_w(int offset, int data); extern int gottlieb_sh_init(const char *gamename); extern void gottlieb_sh_update(void); extern const char *gottlieb_sample_names[]; extern void gottlieb_output(int offset, int data); extern int reactor_IN1_r(int offset); extern int reactor_tb_H_r(int offset); extern int reactor_tb_V_r(int offset); extern int gottlieb_trakball(int data); extern unsigned char *gottlieb_paletteram; extern unsigned char *gottlieb_characterram; extern void gottlieb_paletteram_w(int offset,int data); extern void gottlieb_vh_screenrefresh(struct osd_bitmap *bitmap); static struct MemoryReadAddress readmem[] = { { 0x0000, 0x6fff, MRA_RAM }, { 0x7000, 0x7000, input_port_0_r }, /* DSW */ { 0x7001, 0x7001, reactor_IN1_r }, /* buttons */ { 0x7002, 0x7002, reactor_tb_H_r }, /* trackball H */ { 0x7003, 0x7003, reactor_tb_V_r }, /* trackball V */ { 0x7004, 0x7004, input_port_4_r }, /* joystick */ { 0x8000, 0xffff, MRA_ROM }, { -1 } /* end of table */ }; static struct MemoryWriteAddress writemem[] = { { 0x0000, 0x1fff, MWA_RAM }, { 0x2000, 0x2fff, MWA_RAM, &spriteram, &spriteram_size }, { 0x3000, 0x37ff, videoram_w, &videoram, &videoram_size }, { 0x4000, 0x4fff, gottlieb_characterram_w, &gottlieb_characterram }, /* bg object ram */ { 0x6000, 0x67ff, gottlieb_paletteram_w, &gottlieb_paletteram }, { 0x7000, 0x7000, MWA_RAM }, /* watchdog timer clear */ { 0x7001, 0x7001, MWA_RAM }, /* trackball: not used */ { 0x7002, 0x7002, gottlieb_sh_w }, /* sound/speech command */ { 0x7003, 0x7003, gottlieb_output }, /* OUT1 */ { 0x7004, 0x7004, MWA_RAM }, /* OUT2 */ { 0x8000, 0xffff, MWA_ROM }, { -1 } /* end of table */ }; static struct InputPort input_ports[] = { { /* DSW */ 0x0, { 0, 0, 0, 0, 0, 0, 0, 0 }, { 0, 0, 0, 0, 0, 0, 0, 0 } }, { /* buttons */ 0x02, /* test mode off */ { OSD_KEY_F2 /* select */, 0,0,0,0,0,0,0 }, { 0, 0, 0, 0, 0, 0, 0, 0 } }, { /* trackball: handled by reactor_tb_H_r() */ 0x0, { 0, 0, 0, 0, 0, 0, 0, 0 }, { 0, 0, 0, 0, 0, 0, 0, 0 } }, { /* trackball: handled by reactor_tb_V_r() */ 0x0, { 0, 0, 0, 0, 0, 0, 0, 0 }, { 0, 0, 0, 0, 0, 0, 0, 0 } }, { /* buttons */ 0x00, { OSD_KEY_1, OSD_KEY_2, /* energy & decoy player 1. */ OSD_KEY_ALT, OSD_KEY_CONTROL, /* decoy & energy player 2.
