Code for the sn76477 sound was derived from PinMAME. There is a bug - if you score 1000 and had less than 100, the hundreds digit will be blank. It will of course fix itself during the course of the game. Setting up - if you do not set up the game, each player will get 255 balls. Turn test switch to Setup. Press 1 to advance to next set. Press 5 to adjust the set. Use the manual for a description of each set. After setting up set 16, do not press 1, instead turn the dipswitch to Play. Exit (to save nvram), and restart. Now the game is ready. Very quick guide to a reasonable setup: 06 - 30000 (1st award score) 07 - 50000 (2nd award score) 08 - 70000 (3rd award score) 09 - 90000 (high score) 11 - 1 (1 coin 1 credit) 13 - 3 (3 balls) 15 - 1 (award is a free game) 16 - 1 (match enabled) *******************************************************************************************/ #include "emu.h" #include "machine/genpin.h" #include "cpu/m6502/m6502.h" #include "machine/6532riot.h" #include "machine/timer.h" #include "sound/sn76477.h" #include "speaker.h" #include "spectra.lh" class spectra_state : public genpin_class { public: spectra_state(const machine_config &mconfig, device_type type, const char *tag) : genpin_class(mconfig, type, tag) , m_maincpu(*this, "maincpu") , m_snsnd(*this, "snsnd") , m_switch(*this, "SWITCH.%u", 0) , m_p_ram(*this, "nvram") , m_digits(*this, "digit%u", 0U) { } void spectra(machine_config &config); protected: DECLARE_READ8_MEMBER(porta_r); DECLARE_READ8_MEMBER(portb_r); DECLARE_WRITE8_MEMBER(porta_w); DECLARE_WRITE8_MEMBER(portb_w); TIMER_DEVICE_CALLBACK_MEMBER(nmitimer); TIMER_DEVICE_CALLBACK_MEMBER(outtimer); void spectra_map(address_map &map); private: uint8_t m_porta; uint8_t m_portb; uint8_t m_t_c; uint8_t m_out_offs; virtual void machine_reset() override; virtual void machine_start() override { m_digits.resolve(); } required_device m_maincpu; required_device m_snsnd; required_ioport_array<4> m_switch; required_shared_ptr m_p_ram; output_finder<40> m_digits; }; void spectra_state::spectra_map(address_map &map) { map.unmap_value_high(); map.global_mask(0xfff); map(0x0000, 0x00ff).ram().share("nvram"); // battery backed, 2x 5101L map(0x0100, 0x017f).ram(); // RIOT RAM map(0x0180, 0x019f).rw("riot", FUNC(riot6532_device::read), FUNC(riot6532_device::write)); map(0x0400, 0x0fff).rom(); } static INPUT_PORTS_START( spectra ) PORT_START("SWITCH.0") PORT_BIT(0x01, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("Outhole") PORT_CODE(KEYCODE_X) PORT_BIT(0x02, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("L Outlane 1") PORT_CODE(KEYCODE_W) PORT_BIT(0x04, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("CR Hole") PORT_CODE(KEYCODE_E) PORT_BIT(0x08, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("TR Hole") PORT_CODE(KEYCODE_R) PORT_BIT(0x10, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("R Bumper") PORT_CODE(KEYCODE_Y) PORT_BIT(0x20, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("C Bumper") PORT_CODE(KEYCODE_U) PORT_BIT(0x40, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("L Bumper") PORT_CODE(KEYCODE_I) PORT_BIT(0x80, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("R Sling") PORT_CODE(KEYCODE_O) PORT_START("SWITCH.1") PORT_BIT(0x01, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("L Sling") PORT_CODE(KEYCODE_A) PORT_BIT(0x02, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("R Outlane") PORT_CODE(KEYCODE_S) PORT_BIT(0x04, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("R Rollover") PORT_CODE(KEYCODE_D) PORT_BIT(0x08, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("L Rollover") PORT_CODE(KEYCODE_F) PORT_BIT(0x10, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("L Inside Target") PORT_CODE(KEYCODE_G) PORT_BIT(0x20, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("C Inside Target") PORT_CODE(KEYCODE_H) PORT_BIT(0x40, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("R Inside Target") PORT_CODE(KEYCODE_J) PORT_BIT(0x80, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("CL Target") PORT_CODE(KEYCODE_K) PORT_START("SWITCH.2") PORT_BIT(0x01, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("CL Button") PORT_CODE(KEYCODE_Z) PORT_BIT(0x02, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("TL Button") PORT_CODE(KEYCODE_Q) PORT_BIT(0x04, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("TL Target") PORT_CODE(KEYCODE_C) PORT_BIT(0x08, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("L Outlane 2") PORT_CODE(KEYCODE_V) PORT_BIT(0x10, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("L Outlane 3") PORT_CODE(KEYCODE_B) PORT_BIT(0x20, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("R Pentagon") PORT_CODE(KEYCODE_N) PORT_BIT(0x40, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("L Pentagon") PORT_CODE(KEYCODE_M) PORT_BIT(0x80, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("TL Area") PORT_CODE(KEYCODE_COMMA) PORT_START("SWITCH.3") PORT_BIT(0x01, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("L Area") PORT_CODE(KEYCODE_STOP) PORT_BIT(0x02, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("R Area") PORT_CODE(KEYCODE_SLASH) PORT_BIT(0x04, IP_ACTIVE_LOW, IPT_OTHER) PORT_NAME("Inlane Button") PORT_CODE(KEYCODE_L) PORT_BIT(0x08, IP_ACTIVE_LOW, IPT_COIN1) PORT_BIT(0x10, IP_ACTIVE_LOW, IPT_START1) PORT_BIT(0x80, IP_ACTIVE_LOW, IPT_TILT) PORT_DIPNAME( 0x60, 0x60, "Test Switch" ) // 3-position slide switch PORT_DIPSETTING( 0x60, "Play" ) PORT_DIPSETTING( 0x20, "Setup" ) PORT_DIPSETTING( 0x40, "Test" ) INPUT_PORTS_END void spectra_state::machine_reset() { m_t_c = 0; } READ8_MEMBER( spectra_state::porta_r ) { uint8_t row = (m_porta & 0x18) >> 3; uint8_t key = m_switch[row]->read(); uint8_t ret = ((BIT(key, m_porta & 7)) ?
