[BallaDann]

Thanks bro, it helped

I've purchased mine a while ago from AliExpress and it works just fine. Check this post for hints on how to find them.

Thanks that was the first place I looked. Didn't know they hide the listings now. Makes sense. Not sure if I could trust it tho. My luck I would actually get a deck of cards. Lol then how could you dispute that.

Sorry, was my bad, the STL file have copyright and the owner asked me to remove and do not share, you can DM and I can contact you with the owner then you can get a deal with him.

Where is a good place to buy a Mig flash cart? Preferably Canada, but USA that ships to Canada would be ok. Everywhere I've looked seems to be shut down, or listings removed

I got mine off of Aliexpress for like 40 bucks. Works great.

Was that $40 CDN and what is the name of the seller?

Has anyone had issues with their MigDumper recently not being able to dump latest release games? The .xci folder does not appear.

I think the game in question (just released) has some new form of copy protection potentially. Neither the MIG Dumper, MigDumpTool, or the latest NxDumpTool can seem to dump my cartridge.

What game?

Likely needs an update if you email MiG they might fix it

But idk if they actually respond anymore or care. When things first released they where pretty good at responding to be within 72 hours via their website form and had pushed out bug fixes

If that the troid game... it can be dumped from the switch 1 with the different tools.. just that the dump won't work with the migflash. The migdumper won't either recognize the game (therefore wont be able to dump it either).
Could it be because of the size of the game or a new protection... who knows... just sucks having to carry the original cartridge if travelling

The contact us section of their web doesn't even work any longer, as it will always return an error if you try to message them with anything.

Not working (on my tests):
From the sw2 version cartridges you can't get all the certificates.
Midgumptool will error when trying to read the cartridges (an error inherited from nxdumptool that was set there so the author would get warnings if an area of the cartridge was suddenly populated).
Nx-dumptool (older versions) was not able to retrieve all the certificates needed for the switch 1.
You can actually dump the game (obtaining the xci) but as far as I know, not all the certificates (haven't tried newest versions of nx-dumptool).
When I tried with older versions I was unable to retrieve the "Initial Data" certificate.

What you can do is dump a sw1 game cart and use it in a sw2 with a downloaded upgrade kit.
Keep in mind that the sw2 cartridges have a different "layout" than the switch 1 ones and that the switch2 version ones also have an area that can only be read properly with a switch 2, therefore you might not be able to copy it correctly with a switch 1.

This was the info I was looking for! Thank you!
I'll hunt down the NXDumpTool forums and query there.

Do you know if it is safe to use a up-to-date mig on the SW2?

 

[Drakull]

I'm using mig with fw 1.2.2 with my own dumps on the sw2 so far without bans. How safe it is? can't tell for sure, as Nintendo might release something one day that drops the axe... but so far so good.

 

[Matt1984]

Yep it is droid prime 4. Wasn’t sure if I was allowed to mention the game specifically by name here. Yep it is my legit cart. Just carry the original for now. I tried the contact form for mig flash and yep error

You re not the only one on that boat .
I travel often and between laptops/console/luggage/other stuff, I try to keep as much away from having to carry the cartridges too (losing them during the trael wouldn't be fun, and the more you carry, the easiest is to lose something).

 

[jrgbat]

Most games I've tried haven't worked because it requires online, sometime even to load up the game. Is there a fix?

That doesn't mean they don't work... just that you don't want to use the online connection. (big difference).

Compatibility Issues: MigSwitch-V2 Not Working With “Metroid Prime 4: Beyond”​

I bought an NS1 version of Metroid Prime 4: Beyond and dumped it using the latest nxdumptool-rewrite. I placed the 5 dumped files into my MigSwitch-V2 and plugged it into my Switch, but it always fails to load.
The system shows:

“The gamecard could not be read.”

I’ve run many experiments, and at this point I strongly believe the issue is related to MigSwitch-V2.

My Environment​

• NS1 updated to 21.0.1
• Created emuNAND
• Latest Atmosphère
• Other games run perfectly in emu environment
• Keys dumped via Lockpick_RCM (required by nxdumptool-rewrite)

Experiments Conducted​

1. Dumping comparison
   I dumped Metroid Prime 4: Beyond with both nxdumptool-rewrite and MigDumpTool.
   → Compared the 5 dumped files using md5sum — they are identical.
2. Installing the dump
   Installed the dumped XCI using dbi.nro — installation succeeded, and the game runs normally.
3. Using MigSwitch-V2
   When the 5 “Metroid Prime 4: Beyond” files are on the MigSwitch card,
   
   • NS1 cannot read the gamecard
   • NS2 cannot read the gamecard
     → Both show: “The gamecard could not be read.”
4. Other games work fine
   All my other dumped games load correctly on MigSwitch-V2 — except the newly released Metroid Prime 4: Beyond.

Conclusion​

Based on all my tests, I’m quite certain this is a compatibility issue with MigSwitch-V2

Has anyone else encountered the same issue?
Is there currently any method or workaround to solve it?

Everyone has. This is the third day this has been discussed.

No. Wait for the new firmware for MIG.

No. Wait for the new firmware for MIG.

So the ninjas already know how to detect a MIG card!?
