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.



  • Supports GameBoy (DMG) and GameBoy Color (CGB) emulation
  • Lets you choose the model you want to emulate regardless of ROM
  • High quality 96KHz audio1
  • Battery save support
  • Save states
  • Includes open source DMG and CGB boot ROMs:
    • Complete support for (and documentation of) all game-specific palettes in the CGB boot ROM, for accurate emulation of Gameboy games on a Gameboy Color
    • Supports manual palette selection with key combinations, with 4 additional new palettes (A + B + direction)
    • Supports palette selection in a CGB game, forcing it to run in ‘paletted’ DMG mode, if ROM allows doing so
    • Support for games with a non-Nintendo logo in the header
    • No long animation in the DMG boot
  • Real time clock emulation
  • GameBoy Camera Emulation2
