Kega Fusion

Kega Fusion is a multi-system emulator for Sega’s consoles, developed mainly by one programmer, Steve Snake. It emulates the SG-1000, Master System and Genesis in a single package, along with the Game Gear, Sega CD and 32X.

Kega Fusion was long regarded as one of the best emulators for these systems. Emulating several different consoles in one program is not easy, but it handles them very well, largely thanks to Steve Snake’s focus on accuracy.

He also optimised Kega Fusion so that its accuracy did not come at the cost of performance. It supports extra features such as netplay and screen scaling filters.

Kega Fusion is no longer developed; its last release, version 3.64, came out in 2010. It still runs games well, but for actively maintained alternatives, try Genesis Plus GX or BlastEm for the Genesis and Gearsystem for the SG-1000 and Master System.
