Mesen

Mesen is a multi-system emulator (NES, SNES, Game Boy, Game Boy Advance, PC Engine, Master System/Game Gear) for Windows, Linux and macOS built in C++ and C#.

Development Builds

.NET builds

These builds require .NET 8 to be installed (except the Windows 7 build which requires .NET 6).
For Linux and macOS, SDL2 must also be installed.

• Windows 10 / 11
• Windows 7 / 8 (.NET 6)
• macOS - Intel
• macOS - Apple Silicon
• Linux
• Linux - AppImage

Native builds

These builds don't require .NET to be installed and offer improved start up times.

• Windows 10 / 11: An issue is causing the emulator to sometimes (randomly) freeze when opening or closing windows in the native builds on Windows. Using the native builds on Windows is not recommended until this is fixed.
• Linux (requires SDL2)
• macOS - Intel (requires SDL2)
• macOS - Apple Silicon (requires SDL2)

Notes / limitations

macOS: The macOS build still has a number of limitations (e.g no gamepad support).
