Mesen is a multi-system emulator for Windows, Linux, and macOS. It supports NES, SNES, Game Boy (GB/SGB/GBC), Game Boy Advance, PC Engine, SMS/Game Gear, and WonderSwan (WS/WSC).
MesenCE is a community-managed fork based on Mesen2, created to maintain and expand this emulator into the future.
We are currently just doing development builds. When we launch stable releases, they will be available from the releases page on GitHub.
These builds don't require .NET to be installed. They load more quickly and are recommended over the .NET builds.
- Windows 10 / 11
- Linux x64 (requires SDL2)
- Linux ARM64 (requires SDL2)
- macOS - Intel (requires SDL2)
- macOS - Apple Silicon (requires SDL2)
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.
Other builds are also available in the Actions tab.
- MacOS: Development builds are self-signed, and will require approval via Gatekeeper before they are able to be run.
- SteamOS: See SteamOS.md
