Genesis Plus GX is a source-available Sega SG-1000, Master System/Game Gear, Genesis/Mega Drive and Sega/Mega CD emulator developed by eke-eke. It's developed for the GameCube and Wii (as homebrew) and is only available on other platforms using the libretro core. However, there exists an unofficial Windows SDL (32-bit) port of the emulator that can be downloaded from here, but there are some differences though:

  • The UI is basically based on the original Genesis Plus, but it contains some backported additions and features based on v1.6.0 of Genesis Plus GX.
  • It seems that it is unstable, that's why you will notice some bug-ridden events (like the emulator breaking when closing it, emulation inaccuracies with the Sega SG-1000 and Sega Master System, etc.).
  • Apparently, the author of this rare port goes by the name of Clownacy, and he maintains the code in here for "the purpose to show how to use the Genesis Plus GX core & interface in SDL in particular."

It is claimed that Genesis Plus GX achieves 100% (not counting the unpatched version of GG Aleste 3 and other M2 encrypted games) compatibility with all commercial games released on platforms it supports, all while being made primarily to run on Wii/Gamecube. It is recommended to use this version instead of the original Genesis Plus where possible.
