(check Back to the Future); - Implement external ROM hook-up; - Add remaining missing peripherals, SIO, HDD and w1300a network; - FDC loading without the IPLPRO doesn't work at all, why? - reverse / blanking tvram attributes; - clean-ups! ^^' per-game/program specific TODO: - Dust Box vol. 1-3: they die with text garbage, might be bad dumps; - Dust Box vol. 4: window effect transition is bugged; - Dust Box vol. n: three items returns "purple" text, presumably HW failures (DFJustin: joystick "digital", mouse "not installed", HDD "not installed"); - LayDock: hangs by reading the FDC status and expecting it to become 0x81; - Moon Child: needs mixed 3+3bpp tvram supported, kludged for now (not a real test case); - Moon Child: window masking doesn't mask bottom part of the screen? - Moon Child: appears to be a network / system link game, obviously doesn't work with current MAME / MESS framework; - Marchen Veil I: doesn't load if you try to run it directly, it does if you load another game first (for example Mappy) then do a soft reset; - Mugen no Shinzou II - The Prince of Darkness: dies on IPLPRO loading, presumably a wd17xx core bug; - Multiplan: random hangs/crashes after you set the RTC, sometimes it loads properly; - Murder Club: has lots of CG artifacts, FDC issue? - Orrbit 3: floppy issue makes it to throw a game over as soon as you start a game; - Penguin Kun Wars: has a bug with window effects ("Push space or trigger" msg on the bottom"), needs investigation; - Sound Gal Music Editor: wants a "master disk", that apparently isn't available; - Yukar K2 (normal version): moans about something, DFJustin: "please put the system disk back to normal", disk write-protected? memory map: 0x00000-0x3ffff Work RAM 0x40000-0x5ffff CG RAM 0x60000-0x67fff "Read modify write" area (related to the CG RAM) (0x30-0x33) 0x68000-0x6ffff IPL ROM (0x34-0x37) 0x70000-0x71fff TVRAM (0x38) 0x72000-0x73fff Kanji ROM / PCG RAM (banked) (0x39) 0x74000-0x75fff Dictionary ROM (banked) (0x3a) 0x76000-0x77fff NOP (0x3b) 0x78000-0x7ffff Phone ROM (0x3c-0x3f) ********************************************************************************************************************************/ #include "emu.h" #include "cpu/z80/z80.h" #include "machine/z80pio.h" #include "machine/z80dart.h" #include "machine/i8255.h" #include "machine/wd17xx.h" #include "machine/pit8253.h" #include "sound/2203intf.h" #include "sound/beep.h" #include "machine/rp5c15.h" //#include "imagedev/cassette.h" #include "imagedev/flopdrv.h" #include "formats/basicdsk.h" #define RP5C15_TAG "rp5c15" class mz2500_state : public driver_device { public: mz2500_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag), m_maincpu(*this, "maincpu"), m_rtc(*this, RP5C15_TAG), m_pit(*this, "pit"), m_beeper(*this, "beeper"), m_gfxdecode(*this, "gfxdecode"), m_palette(*this, "palette") { } required_device m_maincpu;
