With the launch of the Nintendo Switch 2 today, one of the first things homebrew enthusiasts set out to do was see if the MIG Switch flashcart would work on the console. Prior to release, retailers of the flashcart were claiming that it worked with the Switch 2, but thanks to the efforts of users on GBAtemp, it appears that it in fact does not work. Beginning with the post in this thread, here, with a photo of a Switch 2 and MIG Switch resulting in an error code. Whether or not there is a workaround or fix is uncertain. Furthermore, a MIG Switch retailer posted about having a Switch 2 unit a month ahead of launch, stating that the unit worked, with what appear to be misleading claims. The potentially shady practices shown here.

Oh no!

Update should make it work on teg Switch 2, as there are no magic data the Switch 2 might access from the cartridge that we can't when dumping it.

 

[Sk17]

People expecting this to magically work day 1 on the Switch 2 were under some serious copium.

 

[raxadian]

Think about it, it doesn’t even sound feasible

Both Sony and Microsoft have remotely bricked stolen consoles in the past and the Switch 2 LITERALLY warns you in their terms and conditions that's possible.

Also if Microsoft can stuck your Windows PC in an eternal boot loop with a failed update then think what Nintendo can do since they have direct access to the Switch 2 hardware, firmware and software since they literally made the thing and the Switch 2 won't even run anything without getting online and updating. So no playing right out the box.

Switch 2 games are also digital only, with Switch 2 gamecards being equivalent to "season pass" discs at best or directly not having even the game first level.

So yes, you have been warned.

Stolen consoles is a very different example and scenario

Not really.
It's designed so that the Switch 1 thinks it's a gamecart. The Switch 2 can play Switch 1 gamecarts so it makes sense that it would work.

What this means is that it must have tell tale signs that it's not an official gamecart so it makes you wonder why the Switch 1 hasn't had an update to detect it.

 

[DeadSkullzJr]

Guys and gals, reminder AGAIN, it is NOT stated anywhere if whether or not the MIG Switch is blocked or if there is some other problem preventing it from working correctly. We can guess, speculate, etc., but DO NOT, I repeat DO NOT say things as if it's fact, do not regurgitate what someone else is claiming to be fact, DO NOT SPREAD MISINFORMATION. The most everyone knows is the fact that the Nintendo Switch 2 doesn't allow for it to work. Just wait for actual information to pop up about it.

maybe it would be best if I made another dedicated switch 2 flashcart thread, like the one I have in the switch 1 section

Then there will be an OP with updated info instead of people relying on long thread chains like this one

Maybe because the Swicth 1 is already open, if they create a fix that can be somehow accessed, the hacker would have a way to study what it is doing

The problem is that again the term and conditions of the Switch 2 say that Nintendo can legally brick your Switch 2 if they think you hacked or modified it. And yes that includes banning any modified controller like if you know you replace your Switch 2 controllers sticks.

When a company is legally allowed to do something the question is not if they will do something but when they will do it.

Even if you do nothing wrong tech companies can fuck you over, as proven many times. For example Sony deleting the movies you digitally bought to watch in your Playstation to give a recent ish example.

So yes this is something people needs to be warned about because no decades old company modifies their term and conditions in a way that will get bad rep unless they are actually planning to use those new terms and conditions.

So your fixed Switch 2 controller getting banned because Nintendo thinks is a third party controller not licensed by Nintendo? They can do that.

Brick your Switch 2 if they think you hacked or modified it? They can do that.

Notice the only really argument people seems to have online is "Nintendo has never done something like that before" or "Remote bricking has only been done in stolen consoles so far" but the problem is, Nintendo wouldn't have modified their terms and conditions if they didn't plan to use the new terms and conditions.

Maybe I am wrong, maybe nothing will happen but I honesty don't want a company bricking something I bought just because they think I violated their terms and conditions.

Neither do I want to pay 80 dollars for a Mario Kart game.

Or reward Nintendo with my money for not fixing Joycon drift and worse now being able to ban a conttoller if I modify it in any way even if is just to fix it.

Yep, might not be actively blocked, might just be "broken".
But as I wrote somewhere else, it would be DUMB if Nintendo didn't block it... embarrassing even.
So my personal belief is that they did block it.
Hopefully it's fixed if that's possible with the mig hardware and if they care enough.

Switch 2 doesn't run Switch games the same as the original console.

 

[cearp]

No, no it doesn't. It means they blocked whatever thing MIG is using, or they changed the way the games are loading.

Sure, but almost any professional will know, it's always good to test.
Of course, I understand that it's within the realms of probability that they didn't test the mig cart on switch 2 - but if I was the manager for the team, I'd make sure it gets tested.

 

[xtrem3x]

Maybe. That is a possibility

Switch 2 doesn't run Switch games the same as the original console.

Makes no difference how it's run. It's the fact that it knows the cart is not genuine that matters

 

[Dausone]

Switch 1 plays games from MigFlash because Switch 1 doesn’t require a full hardware-level check with a game cart. The system just thinks it’s an official game.

Switch 2 blocks this completely, because the system uses hardware authentication. MigFlash or the dumped XCI doesn’t provide the security signatures required to play the game. So in order for the game to play, you would need sigpatches and this would also require custom software installed on the switch 2 to bypass the security checks.

This could never be done by any software update provided by MigFlash. Ever. RIP.

[linuxares]

Hmm.. would surprisingly make sense to have a hardware authentication, but man annoying to need to release a new file/firmware for each new release of a game.

You're ignorant. TOS/EULA means absolutely nothing when it violates the law. You clearly know nothing on the subject. Sony already tried this & it was ruled illegal. Everyone remember when Sony tried banning PS5s in Brazil & lost in court because banning a digital only console is the equivalent of bricking it? Your ignorance of the law is laughable. Sit this one out kid, you're not educated in the least on the subject.

Nintendo risks big money if they actually brick or make consoles fully unusable. In Europe something like this would be calling for big trouble from day one. As others pointed out, they would just ban you from online services and that's it.

AFAIK, MiG Switch team decapped the Switch 1 cart reader chip and obtained keys ( now that I write this... actually not sure, if the device is using asymmetric crypto this wouldn't be possible; maybe it uses some symmetric crypto based HMAC ? ) or... the thing is MiG Switch seems to work at a lower level, so to say, it just reads the same the original cart has, it replays the same of what you read from an original cart, so whatever the original cart has is replayed, including keys/crypto.

TOS may work in some parts of the world but in others you can wipe your darkest holes with the TOS. Europe is an example of it.
