Believe it or not, Nintendo apparently isn't taking too kindly to Switch 2 owners using cartridges on their new consoles that can be used to play pirated Switch games, as some users claim that inserting a certain flash cart has led to their new hardware getting banned.
The MIG Switch (or MIG Flash) is a physical cartridge that can be inserted into Switch consoles to load and play Switch games which have been downloaded onto it – be that via files dumped from games purchased by the user, or pirated copies found online. Think of the R4 cards that could be used on the Nintendo DS systems, and it's basically the same idea.
