> near-perfect emulators

And there's the reason Nintendo isn't doing it. The top priority for them by a massive margin is consistency. The QA they perform for their own products would require an absolutely enormous amount of staff, all for a minuscule payout because there just is not the kind of demand for those games that would justify such a return.

Nintendo's own Switch release of Super Mario Sunshine used an outdated version of Dolphin, one of those imperfect emulators. (People were remarking on the emulator bugs as soon as it was released.) They saw a demand and didn't let QA get in their way.

That's not true, the Switch version of Sunshine runs on an in-house Gamecube/Wii emulator called Hagi. Nintendo have always rolled their own emulators, although curiously their NES emulator uses a ROM header format which originated in the unofficial emulation scene, so they must have used unofficial docs for reference.

Even if Nintendo wanted to use existing emulators, they wouldn't touch a GPL project like Dolphin anyway. They do use open source libraries in their games but never, ever GPL ones for fairly obvious reasons.
