Or they could just, I don't know, not burn out console after console running them constantly so they don't have to spend exuberantly. That's if the they can even produce that process node somehow. If not, making a new fab would cost 10s of millions, to produce old and completely antiquated hardware that they can already emulate on there current hardware.

What do think Nintendo does there development on? You think they run the unity editor on the Switch? They have probably used windows emulators for development since the Gamecube, and they absolutely have there own versions. Which open source emulators are they trying shut down? Something from this decade? If you mean Switch emulators, that's just piracy, which I'm all for, but it's not a exactly a moral high ground.

I thought they had included ripped ROMs, someone mentioned in another thread that were packaging the ROMs the same way. I'm not sure if that means the used the same tools or got to same result another way, buts it's only a way of packaging ROMs.

It's there IP, they can choose what's allowed to be done with it. If they want to emulate it, they can. If they want it to only ever play on a N64DD, then thats also up to them. If they benefit from open source emulators, which I mostly doubt, then they as the fault on the emulator developer for being open source. Close it down, make Nintendo license it if you think it's benefiting them unfairly.

I assure you they are currently runnng there in-development Switch2 games on in an emulated environment as we speak.

You're grossly overestimating the number of consoles they would "burn through" by having a few of their original original hardware set up in their museum. If you're worried about them running constantly, they could easily have a couple consoles per station that get swapped between throughout the day so that no one console is ever on for more than a few hours. People used their regularly NESes and SNESes for several years, I'm sure you could stretch that to decades of you had the expertise and resources of the company that invented the hardware behind you.
You're grossly overestimating the amount of money it would cost to maintain original hardware. As another user said, hobbyists can maintain an original system themselves for decades using mostly off-the-shelf parts. The rare occurrences where a proprietary Nintendo part needs replaced wouldn't cost tens of millions of dollars. There's thousands of shops that can manufacture small runs of custom ICs or circuit boards for a few thousand bucks. They wouldn't need to maintain a custom multi-million dollar facility.

to produce old and completely antiquated hardware that they can already emulate on there current hardware.

Then emulate on your current hardware, if you're going to use emulation! Don't use a Windows emulator from who-knows-where, when you've repeatedly made clear that you're against other parties emulating your hardware! That's certainly more embarrassing by the way, if your Windows emulator crashes and museum goers are greeted by a Windows BSOD or whatever, instead of the Switch home screen or the Nintendo Online interface.

What do think Nintendo does there development on?

We're talking about NES/SNES games here (which Nintendo doesn't develop anymore, btw), because that's what they were caught using a Windows PC and a Windows emulator for. So either they're using someone else's emulator, or they ported the emulator that runs on the switch to run on Windows (which would be a huge undertaking, considering the architecture and OS differences between a Nintendo Switch and a Windows PC).

If you mean Switch emulators, that's just piracy

Emulation is not piracy.

I thought they had included ripped ROMs

Some of the ROMs on their official library contained signatures from popular ROM rippers, which indicates they straight up just downloaded them from one of the various ROM sites they've been trying to shut down for the last couple decades.

It's there IP, they can choose what's allowed to be done with it. If they want to emulate it, they can.

That's fine, I don't have a problem with anyone emulating anything, including Nintendo. My problem lies with their hypocrisy. If they want to emulate NES/SNES games in their own museum, go for it. But at least use your own emulator on your own hardware, given they have the ability to easily do that. Using a Windows PC and a Windows emulator for that is hypocritical.
