/*************************************************************************** Neo-Geo AES hardware Credits (from MAME neogeo.c, since this is just a minor edit of that driver): * This driver was made possible by the research done by Charles MacDonald. For a detailed description of the Neo-Geo hardware, please visit his page at: http://cgfm2.emuviews.com/temp/mvstech.txt * Presented to you by the Shin Emu Keikaku team. * The following people have all spent probably far too much time on this: AVDB Bryan McPhail Fuzz Ernesto Corvi Andrew Prime Zsolt Vasvari MESS cartridge support by R. Belmont based on work by Michael Zapf Current status: - Cartridges run. - Riding Hero runs in slow-mo due to the unemulated comm link MCU in the cartridge. In MAME if dip SW6 is set to ON to enable link play, it runs the same way! On AES there are no dipswitches, and so it always tries to talk to the MCU. Neo-Geo CD hardware Thanks to: * The FBA team (Barry Harris) for much of the CDC / CDD code and system details. ( http://www.barryharris.me.uk/ ) * Mirko Buffoni for a commented disassembly of the NeoCD bios rom. Current status: - NeoCDZ runs, the original NeoCD does not - Might think the tray is open? (check) - Some unknown / unhandled CD commands, code is still a bit messy - CDDA continues to play during loading, should stop it - Games using Raster Effects are broken without a kludge - CPU gets overloaded with IRQs from the timer callback... - Double Dragon doesn't load, it erases the IRQ table - might need better handling of the Vector Table Mapping, or better interrupts (see point above) - Softlist are based on an old Tosec set and should be updated to the TruRip set once we can convert CCD without throwing away gap data etc. ****************************************************************************/ #include "emu.h" #include "cpu/m68000/m68000.h" #include "includes/neogeo.h" #include "machine/nvram.h" #include "cpu/z80/z80.h" #include "sound/2610intf.h" #include "imagedev/cartslot.h" #include "imagedev/chd_cd.h" #include "sound/cdda.h" #include "machine/megacdcd.h" extern const char layout_neogeo[]; /* Stubs for various functions called by the FBA code, replace with MAME specifics later */ UINT8 *NeoSpriteRAM, *NeoTextRAM; //UINT8* NeoSpriteROM; //UINT8* NeoTextROM; UINT8* YM2610ADPCMAROM; UINT8* NeoZ80ROMActive; // was it actually released in eu / asia? #define NEOCD_REGION_ASIA 3 // IronClad runs with a darkened screen (MVS has the same issue) #define NEOCD_REGION_EUROPE 2 // ^ #define NEOCD_REGION_US 1 #define NEOCD_REGION_JAPAN 0 UINT8 NeoSystem = NEOCD_REGION_JAPAN; class ng_aes_state : public neogeo_state { public: ng_aes_state(const machine_config &mconfig, device_type type, const char *tag) : neogeo_state(mconfig, type, tag) , m_tempcdc(*this,"tempcdc") , m_io_in2(*this, "IN2") , m_io_in0(*this, "IN0") , m_io_in1(*this, "IN1") , m_io_mj01_p1(*this, "MJ01_P1") , m_io_mj02_p1(*this, "MJ02_P1") , m_io_mj03_p1(*this, "MJ03_P1") , m_io_mj04_p1(*this, "MJ04_P1") , m_io_mj01_p2(*this, "MJ01_P2") , m_io_mj02_p2(*this, "MJ02_P2") , m_io_mj03_p2(*this, "MJ03_P2") , m_io_mj04_p2(*this, "MJ04_P2") , m_io_ctrlsel(*this, "CTRLSEL") { NeoCDDMAAddress1 = 0; NeoCDDMAAddress2 = 0; NeoCDDMAValue1 = 0; NeoCDDMAValue2 = 0; NeoCDDMACount = 0; NeoCDDMAMode = 0; nIRQAcknowledge = ~0; nNeoCDIRQVectorAck = 0; nNeoCDIRQVector = 0; m_has_sprite_bus = true; m_has_text_bus = true; m_has_ymrom_bus = true; m_has_z80_bus = true; } optional_device m_tempcdc; void NeoCDDoDMA(address_space& curr_space); void set_DMA_regs(int offset, UINT16 wordValue); DECLARE_READ16_MEMBER(neocd_memcard_r); DECLARE_WRITE16_MEMBER(neocd_memcard_w); DECLARE_READ16_MEMBER(neocd_control_r); DECLARE_WRITE16_MEMBER(neocd_control_w); DECLARE_READ8_MEMBER(neocd_transfer_r); DECLARE_WRITE8_MEMBER(neocd_transfer_w); DECLARE_READ16_MEMBER(aes_in0_r); DECLARE_READ16_MEMBER(aes_in1_r); DECLARE_READ16_MEMBER(aes_in2_r); DECLARE_INPUT_CHANGED_MEMBER(aes_jp1); DECLARE_MACHINE_START(neocd); DECLARE_MACHINE_START(neogeo); DECLARE_MACHINE_RESET(neogeo); DECLARE_MACHINE_RESET(neocd); // neoCD UINT8 neogeoReadTransfer(UINT32 sekAddress, int is_byte_transfer); void neogeoWriteTransfer(UINT32 sekAddress, UINT8 byteValue, int is_byte_transfer); INT32 nActiveTransferArea; INT32 nSpriteTransferBank; INT32 nADPCMTransferBank; INT32 NeoCDDMAAddress1; INT32 NeoCDDMAAddress2; INT32 NeoCDDMAValue1; INT32 NeoCDDMAValue2; INT32 NeoCDDMACount; INT32 NeoCDDMAMode; INT32 nIRQAcknowledge; int nNeoCDIRQVectorAck; int nNeoCDIRQVector; bool m_has_sprite_bus; bool m_has_text_bus; bool m_has_ymrom_bus; bool m_has_z80_bus; int get_nNeoCDIRQVectorAck(void) { return nNeoCDIRQVectorAck; } void set_nNeoCDIRQVectorAck(int val) { nNeoCDIRQVectorAck = val; } int get_nNeoCDIRQVector(void) { return nNeoCDIRQVector; } void NeoCDIRQUpdate(UINT8 byteValue); // from the CDC void interrupt_callback_type1(void); void interrupt_callback_type2(void); void interrupt_callback_type3(void); UINT8 nTransferWriteEnable; bool prohibit_cdc_irq; // hack?
