Hello guys, this is my first post here! I just got a MIG Switch card out of curiosity and I was tinkering with it. For those who don't know, it's used by placing XCI dumps as well as other game specific bin files in the sd card of the MIG Switch, and are obtained from the original cartridge by using an app like nxdumptool. Two of these bin files are mandatory to get the game to boot: Initial Data.bin and Certificate.bin. They stay the same for every cartridge of a specific game. Now, if you want to use an XCI dump from a shady website it's impossible to get it to work without those files. By using the Certificate.bin from another game it has no problem, but this does not count for the Initial Data.bin. So I looked for a way to obtain this Initial Data from an XCI file and read a bit of the XCI file documentation from switchbrew dot org. Here's what I understood so far: The Switch checks if the cartridge is valid by doing a challenge–response authentication on the Initial Data. The Package ID is contained both on the XCI and the Initial Data, on positions 0x110 and 0x0 respectively. The Initial Data hash is on the XCI at position 0x160. It is calculated by doing a SHA-256 hash on the full Initial Data content. So I was wondering, is there a way to to construct a functional Initial Data file starting from an XCI dump? I also tried a reverse approach by editing the Package ID in the Initial Data from another game, generating the Initial Data hash and putting it in the XCI file but is not enough to get the Switch believe it's a real game. Sorry if this may seem stupid but let me know what you think.

My dbi language change every time i open it. How to change it to default eng?

How likely is this to get any of the units banned?

So, let's say that I have Switch A and Switch B.

Switch A is an unmodded Mariko. It contains an AC:NH save.
Switch B is a modded unpatched Erista, and it contains JKSV which can extract the file to a format readable by a save editor.

If I went through the complicated process of doing all of these steps:
- Using the official transfer tool to transfer save from Switch A to Switch B
- Copying the received save over from SysMMC to EmuMMC
- Extracting the EmuMMC save with JKSV
- Using the save editor
- Importing the save back to EmuMMC
- Copying it back to SysMMC
- Using the official tool to move it back to Switch A

...how likely am I to get banned on at least one of these units?

The edits won't involve any island/item hacking. I literally just want to change my island name, as I chose a terrible one and Nintendo never allowed changes like this.

IMO there is no reason for emmc to be involved. At some point you have to use homebrew on the sysnand and then connect to Nintendo servers. That will be your risk.
