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 need some help, please.
My Switch OFW is v5.1.0 and was still runing an old SXOS version that didn't support EmuNAND.
I want to be up to date now, so I updated SXOS and built an EmuNAND on a fresh SD Card.
So now I've got a hidden partition of 29.13 GB on my SD Card, and it runs fine.

But when I run incognito by injecting incognito_rcm.bin with SXOS, and launching "Incognito (emuMMC)",
I get:

"Keyblob 0 to 5 corrupt".

What's happening ?
I'm scared to update my EmuNAND with ChoiDuJour until I fix this problem !

Thank you in advance for your help...

EDIT :
I read elsewere that :
"Keyblobs start at 0x180000 in boot0 and are each 0x200 apart (keyblob 0 is at 0x180000, keyblob 1 is at 0x180200, etc)".
And when I hexedit my BOOT0 I see datas at those places (at least it's not filled of 0's).
If it can helps you to help me
