CrabEmu is an emulator for the SG-1000 and Sega Master System, available for Linux, macOS and even the Dreamcast, for anyone who still has one.

CrabEmu was designed to be a fast and effective emulator for Sega's two 8-bit consoles, the SG-1000 and the Master System.

Unlike most emulators, it is not available for Windows.

CrabEmu has high compatibility while keeping good performance, and it can render SG-1000 and Master System graphics at a much higher resolution than the original hardware.

Development of CrabEmu has ended, but its code was used in the OpenEmu project on macOS.
