MIG-FLASH V2:
 
Mig-Flash is the only back-up & development device for ALL Nintendo Switch© consoles, regardless of their version, firmware, type (OLED, regular or Lite) that does not require any installation or modification of the console. Simply plug & play!
 
Is the Mig Dumper included with Mig Switch (card)?

No, it is not. Mig Flash (card) and Mig Dumper are 2 separate products. You will always need Mig Flash cart to play your backups on your console. Mig Dumper is a very convenient but optional method to create those backups. You can either share a Mig dumper between several users or use a hacked Nintendo Flash to create them, as indicated https://migflash.com/#/downloads

How big a microSD does the Mig Flash support?

We have tested all microSD card sizes up to the largest currently available (1.5TB). They are all supported. And although we can't test 2TB yet as it is not available on the market, there is no reason why it wouldn't be compatible. However, keep in mind that a Nintendo© Flash game is only on average 10GB in size, so we recommend using smaller and cheaper cards, and eventually multiples if you own a lot of games.

Can I play online?

You can with your own game backups as long as you respect carefully the instructions in our 'Download' section:
1) Online mode is only recommended with a fully complete game dump
2) If a valid Certificate, Card ID Set, or Card UID is missing, online mode is not recommended as it can lead to a ban.
