// license:BSD-3-Clause // copyright-holders:Andrew Gardner /* Sega LaserDisc Hardware Driver by Andrew Gardner from schematics with help from Daphne Source Todo: -Get LDV1000 games past the strange, pseudo-attract mode! -Implement ldv1000's unknown/undocumented command 0xf2. -Confirm DIPs do what's expected. Also, is Joystick_down really Joystick_up? -Correct IC names/positions for the ROMs - Astron Belt schematics have conflicting data. -Add SEGA/Hitachi VIP9500SG laserdisc player to MAME core & fix all non ldv1000 games to use it. -Write Sprite drawing code. -Hook up character map color PROM. -Confirm palette code (inferred from Daphne source) once its actually used. -Hook up OUT writes. -Add samples. -Confirm banking works. -Character decoding may combine the lower 0x0800 with the upper 0x0800. */ #include "emu.h" #include "cpu/z80/z80.h" #include "machine/ldv1000.h" #include "emupal.h" #include "speaker.h" #define SCHEMATIC_CLOCK (20000000) class segald_state : public driver_device { public: segald_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag), m_laserdisc(*this, "laserdisc"), m_obj_ram(*this, "obj_ram"), m_out_ram(*this, "out_ram"), m_color_ram(*this, "color_ram"), m_fix_ram(*this, "fix_ram"), m_maincpu(*this, "maincpu"), m_gfxdecode(*this, "gfxdecode"), m_palette(*this, "palette") { } void astron(machine_config &config); void init_astron(); private: uint8_t m_nmi_enable = 0; required_device m_laserdisc; required_shared_ptr m_obj_ram; required_shared_ptr m_out_ram; required_shared_ptr m_color_ram; required_shared_ptr m_fix_ram; uint8_t m_ldv1000_input_latch = 0; uint8_t m_ldv1000_output_latch = 0; uint8_t astron_DISC_read(offs_t offset); uint8_t astron_OUT_read(offs_t offset); uint8_t astron_OBJ_read(offs_t offset); uint8_t astron_COLOR_read(offs_t offset); void astron_DISC_write(offs_t offset, uint8_t data); void astron_OUT_write(offs_t offset, uint8_t data); void astron_OBJ_write(offs_t offset, uint8_t data); void astron_COLOR_write(offs_t offset, uint8_t data); void astron_FIX_write(offs_t offset, uint8_t data); void astron_io_bankswitch_w(uint8_t data); virtual void machine_start() override; uint32_t screen_update_astron(screen_device &screen, bitmap_rgb32 &bitmap, const rectangle &cliprect); void astron_draw_characters(bitmap_rgb32 &bitmap,const rectangle &cliprect); void astron_draw_sprites(bitmap_rgb32 &bitmap, const rectangle &cliprect); required_device m_maincpu; required_device m_gfxdecode; required_device m_palette; void mainmem(address_map &map); void mainport(address_map &map); }; /* VIDEO GOODS */ void segald_state::astron_draw_characters(bitmap_rgb32 &bitmap,const rectangle &cliprect) { for (uint8_t character_x = 0; character_x < 32; character_x++) { for (uint8_t character_y = 0; character_y < 32; character_y++) { int current_screen_character = (character_y * 32) + character_x; m_gfxdecode->gfx(0)->transpen(bitmap, cliprect, m_fix_ram[current_screen_character], 1, 0, 0, character_x * 8, character_y * 8, 0); } } } void segald_state::astron_draw_sprites(bitmap_rgb32 &bitmap, const rectangle &cliprect) { /* Heisted from Daphne */ const uint8_t SPR_Y_TOP = 0; /* const uint8_t SPR_Y_BOTTOM = 1;*/ const uint8_t SPR_X_LO = 2; /* const uint8_t SPR_X_HI = 3;*/ /* const uint8_t SPR_SKIP_LO = 4;*/ /* const uint8_t SPR_SKIP_HI = 5;*/ /* const uint8_t SPR_GFXOFS_LO = 6;*/ /* const uint8_t SPR_GFXOFS_HI = 7;*/ for (int spr_number = 0; spr_number < 32; spr_number++) { int spr_base = 0x10 * spr_number; int sy = m_obj_ram[spr_base + SPR_Y_TOP]; int sx = m_obj_ram[spr_base + SPR_X_LO]; if (sx != 0 || sy != 0) logerror("Hey!
