SMS is a free, open-source Sega Master System emulator written in Go for Linux. Its source repository is public on GitHub and described as MIT licensed. The emulator provides complete Zilog Z80 emulation and is described as concurrent. Graphics use an SDL backend with a 2x scaler and fullscreen support. Keyboard controls map the arrow keys to joypad directions, X to Fire 1, and Z to Fire 2. The README documents a Go installation command and shows launching an SMS ROM with the supplied executable. Sound support is listed as a project todo, and writing more tests is also listed as a todo. The stated free and open-source plan costs nothing. The project is focused on Sega Master System emulation, with the listed display and keyboard controls defining its documented user-facing operation.
