I don’t exactly keep up with the latest in emulation, and who knows how Nintendo is going to do things, but my understanding that in a lot of ways GameCube (and WII for that matter) emulation has been in a better place than N64 for a while now, so I’m not too concerned about the switch being able to run it.
While the console itself was less powerful, the N64 is kind of a monster to emulate, it basically speaks a totally different language than any computer (or phone, console, etc) you might try to emulate it on, and there’s a lot of weird special code in individual games that the console needs to deal with, so there’s a lot more for the emulator to do and so you kind of need a comparatively beefy device for the emulation to run well.
GameCube and later consoles work a lot more similarly to how your computer and other devices work, so it’s a lot easier to emulate them.
I’ve seen it explained sort of like if the N64 spoke Chinese, the GameCube spoke Spanish, and your computer speaks Portuguese.
If a Spanish speaker slows down and throws in some hand gestures, a Portuguese speaker will probably more-or-less get the gist of what they’re saying, and Google translate can pretty much fill in the rest. That’s your computer emulating a GameCube game. There’s not too much the emulator actually needs to do, just some minor corrections here and there but mostly things translate pretty cleanly 1:1 between the two languages.
Chinese and Portuguese are wildly different languages though, almost no shared vocabulary, different languages families, even some of the hand gestures may have different meanings, and Google translate is probably going to spit out some weird garbled nonsense if you try to translate anything too complicated through it. It takes a lot more to facilitate communication between the two languages.
I think it depends on the movie
If, after 30 years it still has a lot of cultural relevance, I’d think of it as a “classic” movie.
If it doesn’t, if it hasn’t aged well and/or faded into obscurity, I think it’s fair to think of it as an old movie.
Probably around '95, I would have been watching Star Wars for the first time. It didn’t feel like an old movie to me then and it still doesn’t to this day. Other movies from that same era haven’t aged quite as well and felt “old” to me.
Looking at some of the top movies from '95, some of them are just as enjoyable or relevant today as they were when they released, others feel dated and not relevant to me today.
It’s going to depend on your personal tastes and experiences of course. I can also sprinkle in a lot of platitudes like “you’re only as old as you feel” and “one man’s trash is another man’s treasure”
I think there’s also room for some overlap. There’s classic movies that also feel dated. I think some movies can be both old and classics. You’d be pretty hard-pressed to find someone who wouldn’t agree that, for example, Casablanca, isn’t old, but I think that just about everyone agrees that it’s also a classic. Where the line is is pretty murky.
