![]() ![]() There are 20-bits address and 16-bits data in both CPUs. ![]() There are two CPUs working in Irem M92 board: a NEC V33 CPU and a NEC V30 CPU. There are two sound chips: Yamaha YM2151, DAC chip. The program loads the file " soundcpu.rom" as Z80 ROM. The program loads the file " maincpu.rom" as V30 ROM. There are 16-bits address and 8-bits data in Z80. There are 20-bits address and 16-bits data in V30. There are two CPUs working in Irem M72 board: a NEC V30 CPU and a Zilog Z80 CPU. Load the ROMsĪs an emulator, MAME.NET loads ROMs first. MAME.NET has more functions: save and load state, record and replay input, cheat, cheat search, IPS (patch main ROM), board debugger, CPU debugger. By these steps, MAME.NET emulates the arcade board successfully. Timer callbacks contains: video update, soft reset, CPU interrupt, sound update, watchdog reset and other interrupts. The " cpuexec_timeslice" operation means sequentially execute every CPU for a time slice, and execute timer callbacks. MAME.NET runs at the following steps: load the ROMs, initialize the machine, soft reset the machine, and loop " cpuexec_timeslice" operation. There are some classic boards supported by now: M72, M92, Taito B, Capcom, CPS-1, CPS-1(Qsound), CPS2, Konami 68000, Neo Geo, Namco System 1, IGS011, PGM(PolyGame Master). ![]() By using C# and the powerful integrated development environment - Microsoft Visual Studio, there is no macro and you can debug the supported arcade game anywhere. MAME.NET is a C# based arcade emulator, and it maintains the same architecture of MAME. MAME (Multiple Arcade Machine Emulator) is a free and open source emulator designed to recreate the hardware of arcade game system in software on modern personal computers and other platforms. ![]()
