I haven't tried Sega games on Switch (and I believe some were available on Wii before that?). But I have also played some of my old games on PC emulators. "Save state" / "load state" is indeed very handy. Keyboard mappings is an inferior experience to a real controller, but meh, you get used to it.

If it's important to you, you can get authentic reproduction controllers that work with the Switch or an emulator:
