These passages imply the writers of them lack basic computer literacy and don’t even understand Nintendo’s own systems.
“copied the game ROMs into Yuzu” Yuzu is not a VM or other container and the ROMs are simply stored on disk in their original dumped form… Yuzu doesn’t “store” or “contain” any games.
“any copy not on an authorized cartridge” LOL! What about games downloaded from your own digital marketplace, then?
What about a game you downloaded from Nintendo eShop and stored on an external SD card, which is a standard and well supported storage method on Switch? Is that SD card an “authorized cartridge”?
