/*************************************************************************** Over Drive (GX789) (c) 1990 Konami driver by Nicola Salmoria Notes: - Missing road (two unemulated K053250) - Visible area and relative placement of sprites and tiles is most likely wrong. - Test mode doesn't work well with 3 IRQ5 per frame, the ROM check doens't work and the coin A setting isn't shown. It's OK with 1 IRQ5 per frame. - Some flickering sprites, this might be an interrupt/timing issue - The screen is cluttered with sprites which aren't supposed to be visible, increasing the coordinate mask in K053247_sprites_draw() from 0x3ff to 0xfff fixes this but breaks other games (e.g. Vendetta). - The "Continue?" sprites are not visible until you press start - priorities ***************************************************************************/ #include "driver.h" #include "deprecat.h" #include "video/konamiic.h" #include "machine/eeprom.h" #include "cpu/m6809/m6809.h" #include "sound/2151intf.h" #include "sound/k053260.h" VIDEO_START( overdriv ); VIDEO_UPDATE( overdriv ); static READ16_HANDLER( K051316_0_msb_r ) { return K051316_0_r(machine,offset) << 8; } static READ16_HANDLER( K051316_1_msb_r ) { return K051316_1_r(machine,offset) << 8; } static READ16_HANDLER( K051316_rom_0_msb_r ) { return K051316_rom_0_r(machine,offset) << 8; } static READ16_HANDLER( K051316_rom_1_msb_r ) { return K051316_rom_1_r(machine,offset) << 8; } static WRITE16_HANDLER( K051316_0_msb_w ) { if (ACCESSING_BITS_8_15) K051316_0_w(machine,offset,data >> 8); } static WRITE16_HANDLER( K051316_1_msb_w ) { if (ACCESSING_BITS_8_15) K051316_1_w(machine,offset,data >> 8); } static WRITE16_HANDLER( K051316_ctrl_0_msb_w ) { if (ACCESSING_BITS_8_15) K051316_ctrl_0_w(machine,offset,data >> 8); } static WRITE16_HANDLER( K051316_ctrl_1_msb_w ) { if (ACCESSING_BITS_8_15) K051316_ctrl_1_w(machine,offset,data >> 8); } /*************************************************************************** EEPROM ***************************************************************************/ static const UINT8 default_eeprom[128] = { 0x77,0x58,0xFF,0xFF,0x00,0x78,0x90,0x00,0x00,0x78,0x70,0x00,0x00,0x78,0x50,0x00, 0x54,0x41,0x4B,0x51,0x31,0x36,0x46,0x55,0x4A,0xFF,0x03,0x00,0x02,0x70,0x02,0x50, 0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00, 0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4, 0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03, 0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00, 0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4, 0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03,0x00,0xB4,0x03 }; static const eeprom_interface eeprom_intf = { 6, /* address bits */ 16, /* data bits */ "011000", /* read command */ "010100", /* write command */ 0, /* erase command */ "010000000000", /* lock command */ "010011000000" /* unlock command */ }; static NVRAM_HANDLER( overdriv ) { if (read_or_write) eeprom_save(file); else { eeprom_init(&eeprom_intf); if (file) eeprom_load(file); else eeprom_set_data(default_eeprom,sizeof(default_eeprom)); } } static WRITE16_HANDLER( eeprom_w ) { //logerror("%06x: write %04x to eeprom_w\n",activecpu_get_pc(),data); if (ACCESSING_BITS_0_7) { /* bit 0 is data */ /* bit 1 is clock (active high) */ /* bit 2 is cs (active low) */ eeprom_write_bit(data & 0x01); eeprom_set_cs_line((data & 0x04) ?
