Most sources say this is a game by Nics but I believe Nics to be a company from Korea, this game is quite clearly a Spanish game, we know for a fact that NIX are from Spain so it could be by them instead. For some reason the game isn't saving scores to the EEPROM. Settings and statistics are saved however. The option "AUTO SAVE SCORES" doesn't seem to be honored - the game writes the value to RAM but never reads it. */ #include "emu.h" #include "cpu/nec/nec.h" #include "machine/bankdev.h" #include "machine/i2cmem.h" #include "sound/ay8910.h" #include "emupal.h" #include "screen.h" #include "speaker.h" class hotblock_state : public driver_device { public: hotblock_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag), m_maincpu(*this, "maincpu"), m_palette(*this, "palette"), m_video_bank(*this, "video_bank"), m_i2cmem(*this, "i2cmem"), m_vram(*this, "vram") { } void hotblock(machine_config &config); private: // Devices required_device m_maincpu; required_device m_palette; required_device m_video_bank; required_device m_i2cmem; // Misc int m_port0; // Memory required_shared_ptr m_vram; u8 eeprom_r(); void eeprom_w(u8 data); void port0_w(u8 data); virtual void video_start() override; uint32_t screen_update(screen_device &screen, bitmap_ind16 &bitmap, const rectangle &cliprect); void banked_video_map(address_map &map); void hotblock_io(address_map &map); void hotblock_map(address_map &map); }; u8 hotblock_state::eeprom_r() { return m_i2cmem->read_sda(); } void hotblock_state::eeprom_w(u8 data) { m_i2cmem->write_scl(BIT(data, 1)); m_i2cmem->write_sda(BIT(data, 0)); } void hotblock_state::port0_w(u8 data) { m_port0 = data; m_video_bank->set_bank(m_port0 & ~0x40); } void hotblock_state::hotblock_map(address_map &map) { map(0x00000, 0x0ffff).ram(); map(0x10000, 0x1ffff).m(m_video_bank, FUNC(address_map_bank_device::amap8)); map(0x20000, 0xfffff).rom(); } void hotblock_state::hotblock_io(address_map &map) { map(0x0000, 0x0000).w(FUNC(hotblock_state::port0_w)); map(0x0004, 0x0004).rw(FUNC(hotblock_state::eeprom_r), FUNC(hotblock_state::eeprom_w)); map(0x8000, 0x8001).w("aysnd", FUNC(ay8910_device::address_data_w)); map(0x8001, 0x8001).r("aysnd", FUNC(ay8910_device::data_r)); } // Right?, Anything else? void hotblock_state::banked_video_map(address_map &map) { map(0x000000, 0x00ffff).mirror(0x9f0000).ram().share("vram"); // port 0 = 88 c8 map(0x200000, 0x2001ff).mirror(0x9f0000).ram().w(m_palette, FUNC(palette_device::write8)).share("palette"); // port 0 = a8 e8 -- palette } void hotblock_state::video_start() { save_item(NAME(m_port0)); } uint32_t hotblock_state::screen_update(screen_device &screen, bitmap_ind16 &bitmap, const rectangle &cliprect) { if (~m_port0 & 0x40) { bitmap.fill(m_palette->black_pen(), cliprect); return 0; } for (int y = cliprect.top(); y <= cliprect.bottom(); y++) { int count = (y * 320) + cliprect.left(); for(int x = cliprect.left(); x <= cliprect.right(); x++) { bitmap.pix16(y, x) = m_vram[count++]; } } return 0; } static INPUT_PORTS_START( hotblock ) PORT_START("P1") PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_COIN1 ) PORT_BIT( 0x02, IP_ACTIVE_LOW, IPT_START1 ) PORT_BIT( 0x04, IP_ACTIVE_LOW, IPT_JOYSTICK_UP ) PORT_PLAYER(1) PORT_8WAY PORT_BIT( 0x08, IP_ACTIVE_LOW, IPT_JOYSTICK_DOWN ) PORT_PLAYER(1) PORT_8WAY PORT_BIT( 0x10, IP_ACTIVE_LOW, IPT_JOYSTICK_LEFT ) PORT_PLAYER(1) PORT_8WAY PORT_BIT( 0x20, IP_ACTIVE_LOW, IPT_JOYSTICK_RIGHT ) PORT_PLAYER(1) PORT_8WAY PORT_BIT( 0x40, IP_ACTIVE_LOW, IPT_BUTTON1 ) PORT_PLAYER(1) PORT_BIT( 0x80, IP_ACTIVE_LOW, IPT_BUTTON2 ) PORT_PLAYER(1) // unused?
