Emulation is kind of in a legal grey area, and relies on the free labour of volunteers. Who’s to say that in 50-100 years’ time there will still be people able and/or willing to maintain the emulators? You could also argue that emulation is an imperfect reproduction of the actual gaming experience - emulators can both cause bugs or make the game actually run better than it did when it was released.
That’s the Holo ISO project. It looks pretty experimental and only supports certain hardware (nvidia graphics cards not recommended).
