Because Nintendo Takes Down Games That Are Recreating One Of Their Sold Games. As An Example: They Are Trying To Take Down ROMS, Because They Are Free Versions Of Their Games.
Roms is just a digital copy of the game the reason why yuzu got taken down is because they tell you how to get illegal roms. Roms them self are legal if they are your dumped copy, if not its illegal and that's why they got taken down.
I also wouldn't recommend putting illegal rom sites here because of nintendo, If you put roms sites your post could either get removed or worse this whole game.
I Agree To That Informatiom.
