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.

I dont believe Nico and his flashcard.

Nico has been more reliable then Hedgeberg, who has been banned multiple times under slightly different names. Any small correct information she has provided in the past she has stolen and tried to pass off as her own. I am shocked at the amount of times (h)edgeberg has been allowed back in. If she or her "friends" have not 'done it', then it must be fake is the attitude she loves to flash off as well.

EDIT: Not saying I believe nico's card is real atm however. Not enough proof

Locking this topic as some people have turned it into a shitfest of personal attacks.

Hopefully enough information has been provided to cast doubt where needed about whether or not this is a true functioning flashcart. The lack of a functioning prototype should be a huge red flag.
