My son and I played "Ringout 4x4" at an arcade years ago, and he loved it, and because we had heaps of games at home emulated in one way or another, he said "wouldn't it be cool if WE had Ringout 4x4 at home to play"..... so I went off on a tangent trying to get it going on a PC at home for him... did all the research on that it run a "Sega Naomi" board and after heaps of trial and error, got it playable via "Demul", although I never got the sound quite right.
It's a 1 to 4 player game... not exactly sure if this is the type of game you're looking for, but a pretty cool game anyway.
...or how about "Dragon's Lair" or "Space Ace" with the "Daphne" emulator?...
...once again, not sure if this is what you're after, but if it's any help, I had them all running on an old "single core" processor (about 2.4Ghz) with only about 1Gb ram, maybe 2, Windows XP.
Let me know if I'm on the right track
