SameBoy is a user friendly Game Boy and Game Boy 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 SDL version is also available to Windows and Unix-like systems.

Changelog:

This version is not compatible with save states of older versions.
