/* Intersecti No names on the pcb and the only ascii text is in the sound rom "Intersecti". Has a daughterboard with "Serai-Padova-1" on it Having disassembled the 1911 code roms, I'd guess that there is a rom in the epoxy block. I've not had a chance to wire up the board yet, but it might be possible to write a trojan to display the rom(s) at $8000 */ #include "emu.h" #include "cpu/z80/z80.h" class intrscti_state : public driver_device { public: intrscti_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) { } UINT8 *m_ram; }; static READ8_HANDLER( unk_r ) { return space->machine().rand(); } static ADDRESS_MAP_START( intrscti_map, AS_PROGRAM, 8 ) AM_RANGE(0x0000, 0x1fff) AM_ROM AM_RANGE(0x6000, 0x67ff) AM_RAM AM_RANGE(0x7000, 0x77ff) AM_RAM AM_BASE_MEMBER(intrscti_state, m_ram) // video ram AM_RANGE(0x8000, 0x8fff) AM_ROM ADDRESS_MAP_END static ADDRESS_MAP_START( readport, AS_IO, 8 ) ADDRESS_MAP_GLOBAL_MASK(0xff) AM_RANGE(0x00, 0x00) AM_READ( unk_r ) AM_RANGE(0x01, 0x01) AM_READ( unk_r ) ADDRESS_MAP_END static INPUT_PORTS_START( intrscti ) INPUT_PORTS_END static const gfx_layout tiles8x8_layout = { 8,8, RGN_FRAC(1,3), 3, { RGN_FRAC(0,3), RGN_FRAC(1,3),RGN_FRAC(2,3) }, { 0, 1, 2, 3, 4, 5, 6, 7 }, { 0*8, 1*8, 2*8, 3*8, 4*8, 5*8, 6*8, 7*8 }, 8*8 }; static GFXDECODE_START( intrscti ) GFXDECODE_ENTRY( "gfx1", 0, tiles8x8_layout, 0, 16 ) GFXDECODE_END static VIDEO_START(intrscti) { } static SCREEN_UPDATE(intrscti) { intrscti_state *state = screen->machine().driver_data(); int y,x; int count; bitmap_fill(bitmap, cliprect, get_black_pen(screen->machine())); count = 0; for (y=0;y<64;y++) { for (x=0;x<32;x++) { int dat; dat = state->m_ram[count]; drawgfx_transpen(bitmap,cliprect,screen->machine().gfx[0],dat/*+0x100*/,0,0,0,x*8,y*8,0); count++; } } return 0; } static MACHINE_CONFIG_START( intrscti, intrscti_state ) /* basic machine hardware */ MCFG_CPU_ADD("maincpu", Z80,4000000) /* ?
