Overview
Kega Fusion is a standalone emulator by Steve Snake for a range of classic Sega systems. Its archived project page lists support for Genesis/Mega Drive, Master System, Game Gear, Sega CD, 32X, and several earlier Sega platforms.
The available project page lists Windows, MacOS, and Linux builds, but those are legacy versions rather than evidence of current operating-system support. A 2010 release post identifies version 3.64 for Windows.
