Genesis Plus GX

Genesis Plus GX is a Sega multi-system emulator originally for the Nintendo GameCube and Nintendo Wii, developed by eke-eke. The author claims the emulator has accurate emulation and 100% compatibility with Sega Mega Drive, Mega-CD, Master System, Game Gear, and SG-1000 games. It also has preliminary Pico emulation. The emulator was originally based off Charles MacDonald’s Genesis Plus 1.2a. For Mega-CD games, ISO + WAV, BIN + CUE and ISO + OGG formats are supported; ISO + MP3 is not supported.

Some versions of the emulator were backported to Windows. Genesis Plus GX is also available for a variety of systems as an emulation core of the libretro gaming API.


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.
