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.

Switch Backup Manager!

Not much. It'll either complain with an error or a prompt to update the system OS. I think. Ever since XCI Explorer / Switch Backup Manager showed up I don't ever try installing those anymore.

Thanks! Sounds good. I knew about backup manager but I didnt think to get it since i dont have many backups to manage!

[QUOTE="I believe it needs to be online to contact Nintendo's servers as they have to pay licensing fees for every console that has ExFAT support.
But yes the ExFAT update is on carts, hence why you can extract the .kip1 module from a game to use in CFW.[/QUOTE]

Quick question to embellish my minimum knowledge.
"How does Nintendo add my Switch to the ExFat list if I update my Switch to ExFat via the update on a cart and I never go online?"
It seems that they are paying for your licensing fee only if you go online and some of us never do."
Thoughts or have I exhibited my minimum knowledge?
