Open-source emulator of 8-bit personal computers Sharp MZ-800, MZ-700 and MZ-1500. Developed for Linux and Windows using SDL3 (video/audio) and ImGui (GUI).
Accurately emulates core hardware: CPU Z80, GDG (WHID 65040-032), CTC i8253, PIO Z80, PIO 8255, PSG SN76489AN - with precise internal signal timing.
Supports peripherals: CMT (MZF/MZT/TAP/WAV), FDC WD279x, Quick Disk, ramdisks (MR1R18, Pezik variants), memory extensions, Unicard and IDE8.
Integrated Z80 debugger with inline assembler, memory browser and breakpoints.
Snapshot system for saving/loading complete emulator state (.mzs archives).
Virtual keyboard, autotype, joystick support, variable speed control.
GUI localized into 10 languages. Alternative ROM sets (JSS, WILLY) included.
