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.

Hello,
I've been trying to restore my NAND now for quite awhile and i'm running into an issue.
My NAND is split into 15 different pieces, so i've merged them together using a batch file.
The rawnand.bin file totals at 28,756,768 KB.
Now, i put the file onto my SD CARD, load up Hekate and this is the error i get presented with....
'Size of the SD Card backup does not match, eMMC's selected part size.'
I've been advised to try both exFAT and FAT32 formats but neither of which have made a difference.
I'm not sure what i'm doing wrong, can anyone help?

Try merging them together with something else. Whatever you merged it with initially has made it smaller than what its supposed to be.

Anything you recommend? The current one i'm using is 'join_15_2GBparts_windows' batch file.

CTCaer's GitHub for Hekate has joiner scripts you can use.

Hmm, yeah that's the one i'm using, i'm currently moving my parts over to my other HDD and trying to join them there, i can't see what difference it can make but i don't think there are any other options.
