Owners of the MIG Switch flashcart should be careful when using it with the Nintendo Switch 2, especially when connected to the internet. Nintendo has recently banned users who attempted to use the flashcart with its next-gen console. This ban comes after a firmware update for the MIG Switch that made it compatible with the Switch 2, allowing users to play older games. However, online use of the flashcart, even with legitimate game backups, results in an immediate ban. It’s reported that Nintendo has developed a detection method that flags the use of the flashcart, regardless of the game being played. 
Although the Nintendo accounts tied to these banned consoles remain unaffected for now, this could change as Nintendo may enforce stricter measures against repeat offenders in the future.
The MIG Switch flashcart itself remains functional, but banning it from accessing online services is a serious issue. Players who encounter a ban won’t be able to access multiplayer features, use GameChat, purchase games or DLC from the eShop, download updates, or redeem Game-Key Cards. This limitation becomes particularly troubling given that many launch titles are distributed through Game-Key Cards rather than physical cartridges. With future releases possibly following this trend, the risk of facing restrictions on a banned console could worsen.

Wasn’t this already happening with the original Switch? 🤔 What’s the big deal? #SwitchBan
Seems like Nintendo is just taking things to the next level. Flashcarts were always risky, now they’re more than ever
