Once again, the latest Nintendo Switch exclusive, Pokémon Legends: Arceus, is playable on day one at 4K on PC via Rjujinx; we've embedded some gameplay footage from the YouTube channel Emulators & Gameplay HD at the end of the article. As you might recall, it already happened with games like Monster Hunter Rise, Pokémon Brilliant Diamond and Shining Pearl, and Mario Party Superstars.

The news comes directly from the emulator's developers, who also posted a detailed guide on how to set up the game, even though Pokémon Legends: Arceus should already run on default settings.
