Buffer $415-6 seems involved in the protocol. We currently have slave CPU irq hooked up to vblank, might or might not be correct. - invert order between maincpu and subcpu, subcpu is clearly the master CPU here. - understand why background mirroring causes wrong gfxs on title screen (wrong tilemap paging, missing video bit or it's actually a RMW thing); cleanup - split into driver/video; ***************************************************************************************/ #include "emu.h" #include "cpu/m6502/m6502.h" #include "cpu/m6809/m6809.h" #include "machine/gen_latch.h" #include "sound/ay8910.h" #include "sound/dac.h" #include "sound/volt_reg.h" #include "screen.h" #include "speaker.h" class cntsteer_state : public driver_device { public: cntsteer_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag), m_spriteram(*this, "spriteram"), m_videoram(*this, "videoram"), m_colorram(*this, "colorram"), m_videoram2(*this, "videoram2"), m_maincpu(*this, "maincpu"), m_audiocpu(*this, "audiocpu"), m_subcpu(*this, "subcpu"), m_gfxdecode(*this, "gfxdecode"), m_palette(*this, "palette"), m_soundlatch(*this, "soundlatch") { } /* memory pointers */ required_shared_ptr m_spriteram;
