Check each game's entry on PCGamingWiki. They're a good resource for finding what it takes to get old games running well on modern PCs. A lot of times, the answer is either "buy it on Steam and use a community-made patch" or "buy it on GOG".
I'm curious, what games are you trying to get working?
Getting the mainstream ones out of the way first: 3s, Garou MotW, ST/2X, Tekken 3 (PS1), UMK3, MvC2, CvS2, SC2, KOF '98, Vampire Savior
Got it? Good. But have you played:
Jackie Chan in Fists of Fire: Strange Mortal Kombat-looking game with three Jackie Chans, but surprisingly accessible
Fighter's History Dynamite/Karnov's Revenge: Karnovember is coming! A 1994 fighting game that held up very well
King of Fighters '95: A prime example of SNK's old school style
Fighter's Destiny and Toy Fighter: 3D fighters where certain knockdowns earn you points, and first to 5 or 7 points wins
Street Fighter EX2 Plus: Arika's quirky take on Street Fighter with plenty of unique characters and mechanics
Slap Happy Rhythm Busters: Fast polygonal 2D fighter with simple controls and supers that make a rhythm action game happen
Teenage Mutant Ninja Turtles Tournament Fighters SNES: The good Turtles fighting game. Fun mechanics to learn and break.
Edit: Added videos for the games that didn't have links to a wiki
Thank you for giving the Fediverse some of that Imaginary Network action I crave from Reddit. I tried asking them to move to Kbin and they aren't interested. You and @Martineski have been doing a fine job making quality posts and always citing your sources. I hope Martineski's Imaginary communities come back soon. I want to contribute more to ImaginarySliceOfLife here!
I'd offer my own @FloatingIsFun to join the Imaginary mix, but it wouldn't work because we accept floaty things that aren't fictional and aren't static images. Besides, with that Lemmy/Kbin bug making all my posts appear to come from two hours in the future, I feel like I've already gotten more exposure than I actually deserve.
The Republicans in state legislature asked us to vote to give up our right to vote on things. All they accomplished was making us more angry at them.
Nice work! If Kbin ever gets a mascot, someone will have to draw it flying with balloons so I can make it @FloatingIsFun 's new icon.
Moments like this make me think Mike DeWine isn't dumb enough or evil enough to actually be a Republican. He actually has a soul and he'll make his own party double-down on transphobia if they're so committed to it. We should've still impeached him for screwing up the March 2020 primary election, though.
