Are dumped Nintendo Switch 2 Edition cartridges safe to use / recognizable?
For example Pokemon Legends Z-A or Zelda Tears of the Kingdom cartrdiges like this (they work on Switch 1 as well):

As per https://github.com/DarkMatterCore/nxdumptool/commit/4c9989e59da787a1147bb587143ee974844dc6eb:

With the release of the Nintendo Switch 2, T2 gamecards are now finally out in the wild. These use an alternate chain of trust model based on a per-cart RSA certificate used to control gamecard comms with individual blacklisting support, completely ditching the old titlekey area based chain of trust model (which means these gamecards offer no Initial Data area at all).Both Switch 2 and hybrid ("Switch 2 Edition") gamecards fall into this category whenever they're used under Switch 1

As I understand the Switch 1 can only see the Switch 1 part of the cartridge, and hopefully mig simulates that.
I just wonder if anyone has ever tried using a dumped Switch 2 Edition game and if they work at all or are not supported yet.

There’s no way to even dump switch 2 games

Def not emulate on mig. It would need all need hardware

I meant switch 2 edition games, not switch 2 games.
Supposedly nxdt can do that (meaning dumping the switch 1 part). Am I misinformed?

I see that some folks use the "match version with local users" functionality of the Switch, to update Switch 1 games on the Switch 2 without connecting to the internet.
For those that don't know what I mean, see this video:

What I was wondering, if it's possible to use that feature with a Switch emulator? I see that the modern emulators are able to boot into the Home Menu, but I don't know if every feature is supported and due to my crappy PC, I'm unable to test any of that.

But if so, maybe someone who has the skills, can create an PC/Phone app, which replicates this feature?
Since atmosphere is open source and pretty much reimplemented every aspect of Nintendos code, maybe it's possible to "hack something up"?

Has anyone tried the MIG Switch on the Switch 2, without their own dumps/unique IDs, then factory reseted and brought it online without getting banned? Do the telemetry disappear with a factory reset?

On Switch 1, no, telemetry was still there with a factory reset. So I'm sure its the same on Switch 2.

Figured. Had to ask to be sure thou

local telemetry not synced with N servers are kept on factory reset. only restoring a nand can delete them, but the ones synced with servers will never disappear.

And if you restore a nand to a point before the last sync with N servers, will lead to a ban

Does anyone know if I can get L.A. Noire to work with MIG on a Switch 2?
The game requires additional data from a mandatory download, which (as far as I can tell), comes with a game update?
Can I transfer this data locally with a hacked Switch 1? I'm a bit baffled here, because on the boxart it says it needs a micro SD card for that data.

You should be able to transfer the data from a Switch1 with match local version

The non oled Switch1 came with 32GB (26GB) usable, so that would automaticly require an SD card to download the game data

Another question - does anyone elses Switch 2 press the MIG v2 button, when the cartridge door/flap is closed?
Once I open the flap again, the MIG automatically changes to the next game, which indicates, that the flap is pressing the MIG button the entire time.
