The Switch Flashcart Thread (Mig Switch etc.)

BREAKING NEWS

As per TotalJustice findings, previously, on MIG firmware 1.1.9 I performed this test

1. Performing an untrimmed dump of a cart with nxdumptool-rewrite
2. Putting the untrimmed dump on the MIG cart
3. Performing an untrimmed dump of the MIG cart with nxdumptool-rewrite
4. Comparing the CRC of both dumps getting the same exact CRC

Then

1. Performing a trimmed dump of a cart with nxdumptool rewrite or with the MIG USB dumper
2. Putting the trimmed dump on the MIG cart
3. Performing an untrimmed dump of the MIG cart with nxdumptool rewrite
4. The dump crashed and aborted when surpassing the ValidDataEndAddress

This to confirm with a different experiment that MIG carts with trimmed dumps are functionally different from OG carts and therefore potentially detectable.

Today I performed the first (untrimmed dump) experiment with the 1.2.0 firmware and step 3 resulted in a crash and abort of the dump process (just like the second trimmed dump experiment). Therefore in my findings, today, any MIG cart is potentially detectable by Nintendo even on old Switch 1 and with untrimmed dumps... I highly suggest to NOT USE MIG carts until further investigation.

TotalJustice can you please confirm (or hopefully debate) my findings with Sphaira?
I really hope I did something wrong.
Thank you in advance.

Sorry for the cross post with the Switch 2 Forum, but this IMHO is way too important.

From The Verge, Nintendo will take your Switch 2 offline forever if you use a Mig flash cartridge

The 3d models I made have been deleted due to bad actors on Etsy stealing and printing off of my work

All while I’m about to be homeless due to not finding a job. Fuck Etsy and leechers

If yall can please report the listing

Of coiurse they are going to say that. They don't want people buying it since they couldn't get the device made illegal. Hopefully Mig Flash figures out how Nintendo is detecting it and can fix it with a software or hardware revision.

Received my mig flash v1 today
But i will wait for further investigation/update regarding ban issue and the ability to update game /add DLC through the mig itself.

Playing game with unable to update it, is realy considerable drawback and ban make things worse, because you can not update game through Nintendo server.

You cannot add game updates/DLC directly to the Mig Flash. You can only use legitimately purchased DLC that already works on the Switch you want to use Mig Flash on and for Game updates they too must have originally been downloaded directly from Nintendo or transferred from another Switch using the version match feature. No fake signed DLC or updates will work.

Will it get detected even if you never lunched a game on mig switch. You see I tried putting it after I got my Switch 2 just to test and it shows the games of course but I did not dare to run the games.

Unknown at this time.

I recently bought an oled model despite me having a pc, deck oled etc. So what if I never connect this oled to the internet & use the mig switch? Will i somehow get banned with an offline system?

That’s somehow a weird question IMHO… if you keep your switch perpetually offline you’re the one who banned your console…

If you do that, the console can log it and be marked for a ban later when it goes online. And a factory reset can not prevent that. You will lower the resale value of the console.

How are Mig Switches detected from the hardware (voltage changes) or software side (cartridge keys)?
I mean it's obvious that console generates flagged telemetry, which results in a ban, but nobaday confirmed, from where exactly?

Still unconfirmed

Yes, but software seems unlikely (considering the telemetry required for the DB actions).
So I guess it's hardware changes in the new console.

There are things that we know Nintendo can detect, even on the Switch 1, like trimmed ROMs. We need to stop using trimmed ROMs for starters. As for anything else they can detect, nobody publicly knows yet.

With MIG firmware 1.2.0 there’s a known methodology for detecting the flash cart regardless of trimmed or untrimmed dumps. Using trimmed vs untrimmed made a difference up to 1.1.9.

What was less detectable, trimmed or untrimmed?

With 1.1.9 there was no publicly known methodology for detecting untrimmed dumps, but Nintendo evidently found one used on Switch 2. Firmware 1.2.0 seems to trick Nintendo, but now there’s a publicly known methodology for detecting both trimmed and not trimmed dumps… it seems N isn’t using that.
All seems to revolve around OOB reads, but the fact that we can detect MIG is IMHO worrying… I mean, I’ll keep my flashcarts in a drawer at least until I can’t detect them anymore and we have enough reports of N not detecting them.

OOB Reads?
