SameBoy is a user friendly GameBoy and GameBoy Color emulator for macOS. SameBoy is extremely accurate and includes a wide range of powerful debugging features, making it ideal for both casual players and developers. In addition to accuracy and developer capabilities, SameBoy has all the features one would expect from an emulator – from save states to scaling filters. An experimental SDL version is available to Windows and Unix-like systems.
