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.
