Actually Kega fusion has been maintained at least to some degree for YEARS, well over 10. It has always just worked on both windows and *buntu for me over the years/decades. it’s also fairly efficient HOWEVER i haven’t tried to run it on anything lower than Pentium 3 yet.
The author has dubbed this new “official” page to get it as of a year or 3 ago. he originally hosted it on his page
I have yet to hear of any accuracy problems with it. like i said it’s always just worked as far as i know. i will note i don’t use net play.
i used to think snes9x was the best SNES emulator untill some youtube video called me a paste eater and showed several games which i have never played before, displaying some noticeable glitches of course that was some years ago.
I can’t say i’ve tested KF as in depth as that but, i suppose that’s factor emulators. Do they work well or do they appear to work well until one gets in a week long game every day after work.
Then again i suppose that’s like my opinion man, i’m no professional or developer either. For all i know i wouldn’t be surprised if i can add all my Kega fusion games manually once i figure out how to work Lutris. (i dled it 5 mins ago)
EDIT: I don’t use OSX all the time but, it’s worked on OSX for me as well.
