The project was previously hosted on SourceForge: https://sourceforge.net/projects/mz800emu/

Source code is no longer updated on SourceForge - all development now happens here on GitHub. The SourceForge page will continue to receive release archives only (binary distributions for users who prefer to download from there).

• Emulation of three Sharp MZ-series machines:
  • Sharp MZ-800
  • Sharp MZ-700
  • Sharp MZ-1500
• Cycle-accurate Z80A CPU emulation (uses the z80-mz800 library)
• Faithful emulation of original chips:
  • GDG WHID 65040-032 (video controller)
  • i8253 CTC, Z80 PIO, i8255 PIO
  • SN76489AN PSG
• Precise internal signal timing
• Wide range of supported peripherals:
  • Cassette (CMT): MZF, MZT, TAP, WAV
  • Floppy disk controller (FDC WD279x)
  • Quick Disk
  • RAM disk, memory extensions
  • Unicard
  • IDE8 hard disk interface
• Integrated Z80 debugger:
  • Disassembler with inline assembler
  • Memory browser with heatmap
  • Breakpoints, watchpoints, symbols, bookmarks, variables
• Multi-platform GUI:
  • Virtual keyboard, autotype
  • Joystick support
  • Variable emulation speed
  • Snapshot system (.mzs)
• Full localization into 10 languages (cs, de, en, es, fr, it, ja, nl, pl, sk, uk)

• C / C++ (C11 / C++17)
• SDL3 for video, audio, input
• Dear ImGui for the GUI
• GLib for utilities
• libcurl and minizip-ng for I/O
• CMake build system (also supports legacy GNU make on MSYS2)

• Linux (tested on Ubuntu 24.04)
• Windows (MSYS2/MINGW64 toolchain)
• BSD systems may work but are not regularly tested

Detailed build instructions are available in docs/:

• docs/build_ubuntu.md - building on Ubuntu / Linux
• docs/build_windows.md - building on Windows via MSYS2
• docs/build_osx.md - building on macOS

Quick build (when dependencies are already installed):

cmake -S . -B build -G Ninja
cmake --build build

• docs/ - user-facing build and usage documentation, changelog

The emulator builds on a family of related libraries and tools maintained in the same author's account:

• z80-mz800 - Z80A CPU core and disassembler
• TapeMZ - tape archive format for Sharp MZ
• mzdisk - disk image tools for Sharp MZ
