Nintendo has recently implemented bans on certain Switch 2 consoles, primarily targeting units suspected of utilizing unauthorized third-party devices. Despite the new console's record-breaking sales performance since its launch, the Japanese gaming giant remains vigilant against potential system exploits. Reports indicate that some Switch 2 units have been banned within just two weeks of release, demonstrating Nintendo's proactive approach to system security.

The company has maintained a firm stance against copyright infringement throughout its history. Recent examples include legal action against the developers of Palworld for alleged similarities to Pokemon gameplay mechanics, and the 2018 shutdown of LoveROMs and LoveRetro for software piracy. This consistent enforcement policy now extends to the Switch 2's early adopters who attempt to modify their systems.

Online communities have reported that Switch 2 consoles connected to MIG Flash devices are receiving bans. This third-party tool enables users to run multiple games by mimicking legitimate game cartridges through a modified microSD card. While some users employ MIG Flash for legitimate game storage, Nintendo appears to have developed detection methods for these devices on their new console.

Banned Switch 2 consoles lose access to all online services permanently. Furthermore, these bans void the device's warranty as they directly violate Nintendo's terms of service. Interestingly, MIG Flash markets itself as supporting 'self-dumped' game files from legally purchased cartridges, claiming not to modify the console hardware itself. However, evidence suggests widespread use for running pirated Nintendo games, particularly retro titles.

In response to these bans, the MIG Flash manufacturer has released an updated V2 model claiming Switch 2 compatibility, even demonstrating it running The Legend of Zelda: Echoes of Wisdom. This development raises questions about whether Nintendo will pursue legal action against the device makers, following their history of targeting piracy facilitators.
