What makes it better than the other Sega emulators?

I ask because I'm very wary about including closed source things that probably have a billion alternatives.

According to http://emulation.gametechwiki.com/index.php/Kega_Fusion the only advantage that kega fusion has over what is currently offered is superior 32X emulation. On the other hand, it's closed source and limited to x86-32.

According to this comparison sheet, Kega Fusion is the only Linux compatible emulator that has full speed emulation and full compatibility with all commercial games. It also supports the Sega Master System, Game Gear, and older Sega consoles that the other emulators do not, which would normally require their own individual emulators (where as Kega Fusion would be an all-in-one solution).

From my research, most Open-Source Linux compatible Sega emulators have been abandoned and are no longer maintained, while also not being as performative or compatible as Fusion. There are only two that are still receiving updates, these are:

• BlastEm!, which only supports the Genesis (no add-on support for the 32x or Sega-CD, or other SEGA consoles), has rather spotty compatibility, can experience slow-down on many titles, and is significantly less user-friendly (requiring the use of a text configuration file for mapping controls, and all other options. It has no GUI).

• Gens/GS II, which is a rewrite of Gens/GS, but is still in the prototype stages even after 6 years of development, and missing major features. It will likely not be ready for quite some time.

Realistically, the original Gens/GS is the only other open-source option that can somewhat compete with Kega Fusion. However development of it stopped in 2010, it has less features (no support for older consoles), and doesn't have the same level of performance or compatibility.

At the end of my search for an open-source emulator to submit, I could only conclude that none of them are as good as Kega Fusion, unfortunately. :(

You've completely omitted http://segaretro.org/Genesis_Plus_GX which already does everything but 32X. And it's probably the only actively maintained these days.

Ah, you're right. I did not realize it relied on 32-bit dependencies, I believe that makes it ineligible for inclusion? If so, I apologize for making this package request :(

Oh bugger. I can't believe I missed that! And it looks like it's already included in RetroArch as well. I agree, it seems the only thing Fusion has going for it now is 32X emulation.

I feel a bit embarrassed now...
