Super Street Fighter II (DOS) Looks nearly arcade perfect and it's got remixed music.
Biohazard 2 Sourcenext (Windows) Probably the best way to play RE2 classic outside of emulation.
Final Fantasy VIII (Windows) Good port I think, bonus it comes with Choco World the Pocketstation minigame.
Dynasty Warriors 4 Hyper (Windows) Higher resolution than PS2 with dynamic shadows.
Please share some of your own finds I want to get a list going.
edit: A couple more I can think of
Final Fantasy XI (Windows)
Virtua Fighter 2 (Windows) Has a cool feature where the computer ai can learn from you, later used in Virtua Fighter 4 iirc.
Samurai Showdown 2 (DOS) I think it's DOS anyway. Looks arcade perfect.
The Windows 95 version of Panzer Dragoon is very cool, even has DirectX(3) support.
Rez Infinite bangs. (This is not /vr/ dreamcast is retro lmao)
Biohazard 3 Sourcenext is also cool, the Sourcenext versions have backgrounds rendered at 1280×960 and look great. Sadly Resident Evil 1 PC backgrounds are only like 240p or whatever.
Dino Crisis was on Windoze.
The Amstrad CPC version of Donkey Kong is somehow one of its best ports??
Moon Remix RPG came out in English on Steam recently.
Fucking, apparently Grandia II had a port to Windows XP back in the day.
The JP Dreamcast rts Hundred Swords by my fav chads Smilebit was on PC.
