It requires an MV-1B or MV-1C system for the output header. There are unpopulated locations for four 15-pin D connectors, so it could theoretically be used with AES joysticks. It won't work with mahjong panels because the outputs aren't demultiplexed. **********************************************************************/ #include "emu.h" #include "kizuna4p.h" //************************************************************************** // DEVICE DEFINITIONS //************************************************************************** DEFINE_DEVICE_TYPE(NEOGEO_KIZ4P, neogeo_kizuna4p_device, "neogeo_kiz4p", "SNK NEO-FTC1B JAMMA Splitter") static INPUT_PORTS_START( neogeo_kiz4p ) PORT_START("JOY1") PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_JOYSTICK_UP ) PORT_PLAYER(1) PORT_BIT( 0x02, IP_ACTIVE_LOW, IPT_JOYSTICK_DOWN ) PORT_PLAYER(1) PORT_BIT( 0x04, IP_ACTIVE_LOW, IPT_JOYSTICK_LEFT ) PORT_PLAYER(1) PORT_BIT( 0x08, IP_ACTIVE_LOW, IPT_JOYSTICK_RIGHT ) PORT_PLAYER(1) PORT_BIT( 0x10, IP_ACTIVE_LOW, IPT_BUTTON1 ) PORT_PLAYER(1) PORT_BIT( 0x20, IP_ACTIVE_LOW, IPT_BUTTON2 ) PORT_PLAYER(1) PORT_BIT( 0x40, IP_ACTIVE_LOW, IPT_BUTTON3 ) PORT_PLAYER(1) PORT_BIT( 0x80, IP_ACTIVE_LOW, IPT_BUTTON4 ) PORT_PLAYER(1) PORT_START("JOY2") PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_JOYSTICK_UP ) PORT_PLAYER(2) PORT_BIT( 0x02, IP_ACTIVE_LOW, IPT_JOYSTICK_DOWN ) PORT_PLAYER(2) PORT_BIT( 0x04, IP_ACTIVE_LOW, IPT_JOYSTICK_LEFT ) PORT_PLAYER(2) PORT_BIT( 0x08, IP_ACTIVE_LOW, IPT_JOYSTICK_RIGHT ) PORT_PLAYER(2) PORT_BIT( 0x10, IP_ACTIVE_LOW, IPT_BUTTON1 ) PORT_PLAYER(2) PORT_BIT( 0x20, IP_ACTIVE_LOW, IPT_BUTTON2 ) PORT_PLAYER(2) PORT_BIT( 0x40, IP_ACTIVE_LOW, IPT_BUTTON3 ) PORT_PLAYER(2) PORT_BIT( 0x80, IP_ACTIVE_LOW, IPT_BUTTON4 ) PORT_PLAYER(2) PORT_START("JOY3") PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_JOYSTICK_UP ) PORT_PLAYER(3) PORT_BIT( 0x02, IP_ACTIVE_LOW, IPT_JOYSTICK_DOWN ) PORT_PLAYER(3) PORT_BIT( 0x04, IP_ACTIVE_LOW, IPT_JOYSTICK_LEFT ) PORT_PLAYER(3) PORT_BIT( 0x08, IP_ACTIVE_LOW, IPT_JOYSTICK_RIGHT ) PORT_PLAYER(3) PORT_BIT( 0x10, IP_ACTIVE_LOW, IPT_BUTTON1 ) PORT_PLAYER(3) PORT_BIT( 0x20, IP_ACTIVE_LOW, IPT_BUTTON2 ) PORT_PLAYER(3) PORT_BIT( 0x40, IP_ACTIVE_LOW, IPT_BUTTON3 ) PORT_PLAYER(3) PORT_BIT( 0x80, IP_ACTIVE_LOW, IPT_BUTTON4 ) PORT_PLAYER(3) PORT_START("JOY4") PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_JOYSTICK_UP ) PORT_PLAYER(4) PORT_BIT( 0x02, IP_ACTIVE_LOW, IPT_JOYSTICK_DOWN ) PORT_PLAYER(4) PORT_BIT( 0x04, IP_ACTIVE_LOW, IPT_JOYSTICK_LEFT ) PORT_PLAYER(4) PORT_BIT( 0x08, IP_ACTIVE_LOW, IPT_JOYSTICK_RIGHT ) PORT_PLAYER(4) PORT_BIT( 0x10, IP_ACTIVE_LOW, IPT_BUTTON1 ) PORT_PLAYER(4) PORT_BIT( 0x20, IP_ACTIVE_LOW, IPT_BUTTON2 ) PORT_PLAYER(4) PORT_BIT( 0x40, IP_ACTIVE_LOW, IPT_BUTTON3 ) PORT_PLAYER(4) PORT_BIT( 0x80, IP_ACTIVE_LOW, IPT_BUTTON4 ) PORT_PLAYER(4) PORT_START("START1") PORT_BIT( 0xfa, IP_ACTIVE_LOW, IPT_UNUSED ) PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_START1 ) PORT_BIT( 0x04, IP_ACTIVE_LOW, IPT_START2 ) PORT_START("START2") PORT_BIT( 0xfa, IP_ACTIVE_LOW, IPT_UNUSED ) PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_START3 ) PORT_BIT( 0x04, IP_ACTIVE_LOW, IPT_START4 ) INPUT_PORTS_END //------------------------------------------------- // input_ports - device-specific input ports //------------------------------------------------- ioport_constructor neogeo_kizuna4p_device::device_input_ports() const { return INPUT_PORTS_NAME( neogeo_kiz4p ); } //************************************************************************** // LIVE DEVICE //************************************************************************** //------------------------------------------------- // neogeo_kizuna4p_device - constructor //------------------------------------------------- neogeo_kizuna4p_device::neogeo_kizuna4p_device(const machine_config &mconfig, const char *tag, device_t *owner, uint32_t clock) : device_t(mconfig, NEOGEO_KIZ4P, tag, owner, clock), device_neogeo_ctrl_edge_interface(mconfig, *this), m_joy(*this, "JOY%u", 1U), m_ss(*this, "START%u", 1U) { } //------------------------------------------------- // device_start - device-specific startup //------------------------------------------------- void neogeo_kizuna4p_device::device_start() { m_ctrl_sel = 0; save_item(NAME(m_ctrl_sel)); } //------------------------------------------------- // in0_r //------------------------------------------------- uint8_t neogeo_kizuna4p_device::in0_r() { return m_joy[BIT(m_ctrl_sel, 0) << 1]->read() & ~(BIT(m_ctrl_sel, 2) << (BIT(m_ctrl_sel, 0) | 4)); } //------------------------------------------------- // in1_r //------------------------------------------------- uint8_t neogeo_kizuna4p_device::in1_r() { return m_joy[(BIT(m_ctrl_sel, 0) << 1) | 1]->read() & ~(BIT(m_ctrl_sel, 2) << (BIT(m_ctrl_sel, 0) | 4)); } //------------------------------------------------- // read_start_sel //------------------------------------------------- uint8_t neogeo_kizuna4p_device::read_start_sel() { return m_ss[BIT(m_ctrl_sel, 0)]->read(); } //------------------------------------------------- // write_ctrlsel //------------------------------------------------- void neogeo_kizuna4p_device::write_ctrlsel(uint8_t data) { m_ctrl_sel = data; }
