Nintendo has won a court case in the Netherlands confirming that selling "circumvention devices" for the Switch, such as the MIG Switch Card, is unlawful. The Hague District Court ruled against an online seller who was "dropshipping" the devices from Asia via websites including r4switch.nl, ther4card.com and r4switch.co.uk, finding that offering and selling MIG Switch Cards and Dumpers infringed Nintendo's copyrights because the devices are primarily designed to bypass the console's security measures and enable piracy. Nintendo says the ruling strengthens the legal basis for rights holders to combat piracy through technological protection measures, and it has ordered the defendant to stop selling the products.

Nintendo drew a parallel with a landmark 2010 ruling by the same court against sellers of "R4 cards" for the Nintendo DS, which were similarly found to enable piracy. The company noted this follows a September 2025 US case in which Nintendo of America was awarded $2 million in damages against MIG Switch distributors, and its recent removal of hundreds of Switch emulator repositories from GitHub. Nintendo's statement urged players to "avoid purchasing or using circumvention devices, circumvention software or unauthorised copies of video games," warning this risks interfering with the functionality of genuine Nintendo hardware and software.
