Is the MIG Switch illegal now?

The District Court of The Hague ruled that selling the MIG Switch Card and MIG Switch Dumper is unlawful and ordered the seller in the case to stop immediately. That ruling is about sales under Dutch law. It does not create a criminal penalty for owning one, and the legal position on possession varies by country.

Does the ruling disable a MIG Switch cartridge I already bought?

No. The court ordered a seller to stop selling the devices. There is no recall, no remote kill switch and nothing in the decision that touches consoles or cartridges already in circulation. The effect is on where you can buy one, not on hardware people already have.

What is the difference between the MIG Switch Card and the MIG Switch Dumper?

The MIG Switch Card is a flash cartridge that fits an unmodified Nintendo Switch and loads game files stored on a microSD card. The MIG Switch Dumper is a separate device that reads a genuine retail cartridge and saves its contents as a file. The court order covers both.

Can Nintendo ban my console for using a flash cartridge?

Yes. Nintendo bans consoles it detects running unauthorised software, which cuts off online play and eShop access while the console still works offline. Those bans are not tied to this court case and are applied by Nintendo directly. Reversals happen only when Nintendo concludes the detection was wrong.

Does this affect Switch 2 as well as the original Switch?

The case concerns devices built around the Switch cartridge format, which both the original Switch and Switch 2 use. The court order is aimed at the sale of those devices rather than at a specific console generation, so it is not limited to one of them.

MIG Switch Ban: Dutch Court Rules Card Sales Unlawful

A Dutch court has ruled that selling the MIG Switch Card and the MIG Switch Dumper is unlawful, and the MIG Switch ban it produced orders one online seller to stop offering them at once. The District Court of The Hague made the ruling this week in a case Nintendo brought against a dropshipper who moved the flash cartridges into Europe from suppliers in Asia.

The devices are not emulators and they are not mod chips. A MIG Switch Card is a flash cartridge that slots into a stock, unmodified Nintendo Switch and loads game files copied onto a microSD card. The MIG Switch Dumper is the companion box that reads a genuine retail cartridge and writes its contents out as a file. Together they let a console play copies of games without any hardware modification, which is the part Nintendo argued in court.

What the MIG Switch ban actually covers

Nintendo's complaint targeted a seller running three websites, with stock shipping straight from Asia to buyers rather than through a warehouse in the Netherlands. The court ordered that seller to stop offering the cards immediately, and extended the order to any other hardware or software built to get past the Switch's protection measures.

Published reports differ on how far the decision reaches. Some accounts describe it as closing off sales across the EU. What the decision does on the record is bind the seller named in the case and declare the sale of those circumvention devices unlawful under Dutch law. No damages figure has been published for this case.

Court: District Court of The Hague, Netherlands
Devices named: MIG Switch Card and MIG Switch Dumper
Order: immediate stop on sales, plus other circumvention hardware and software
Defendant: an online seller operating three storefronts, dropshipping from Asia
Damages: none announced

Does it affect a cartridge you already own

No. This is a sales ruling, not a recall, and nothing in it reaches into consoles or switches off cartridges already in people's hands. The practical effect is on supply: the storefronts named in the case are the ones that have to stop.

Using one carries a separate risk that has nothing to do with this court. Nintendo bans consoles it detects running unauthorised software, and those bans cut off online play and the eShop while leaving the console working offline. The company has occasionally had to unpick that enforcement when it caught the wrong people, as it did with the wave of accidental Switch 2 console bans behind error 2124-4508. A ban that lands because of a flash cartridge does not get reversed.

Nintendo's line, and the precedent behind it

Nintendo framed the outcome as a win for developers rather than for itself, saying it promotes and fosters game development and supports developers who legitimately create new games. Its advice to players was to avoid buying or using circumvention devices, circumvention software or unauthorised copies, which it says raises the risk of interfering with how authentic consoles and games behave.

The company pointed back to a 2010 Dutch ruling against R4 cards for the DS, which followed the same shape: a flash cartridge that needed no soldering, sold openly online, then declared unlawful to sell. A separate US case reached judgment in September 2025, when a court ordered a MIG Switch seller to pay $2 million.

This is one piece of a much wider push through 2026. Nintendo has pursued emulator repositories, resellers and individual distributors across several jurisdictions, and it has done so while the Switch 2 install base grew and the original Switch stayed in circulation. Both generations share the cartridge format the MIG devices target.

What a Switch owner should take from this

If the appeal of a flash cartridge was backing up games you already bought, the legal answer in the Netherlands is now clearly no for the seller side of that transaction. If it was price, the legitimate route is the storefront calendar: Nintendo's own Customer Appreciation Sale, which runs September 13 to 26 with 30% off, is the sort of window where first-party games actually move.

For retro libraries specifically, emulation on hardware you own sits in a different legal position from a device sold to defeat a console's protection, and our guide to the best GBA games on Android covers the legal-dump question directly. On the console itself, keeping current matters more than it used to now that firmware adds real features, as the Switch 2 update 23.0.0 that added VRR in TV mode showed. And if hardware cost is the pressure point, the Switch 2 price increase in the UK to £419.99 is the number that moved most recently.
