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'm going to try my best to explain the situation.
So i have been hacking my switch for a while and have no issues ever.
Ever since playing animal crossing ive had numerous problems ranging from my system failure to not being able to connect the switches together at all!
The most recent is that i match the versions of the game together and that works fine.
Then i go into the game and try to connect them to join each other's island and suddenly i am unable to connect over LAN, never going online.
Then if i exit and try to match over lan with any other game, for example Pokemon, it finds each other but then cannot update.
Sometimes it didn't even find each other.
Have i blown a fuse? Has it updated without me knowing?
How can i fix this issue? I am able to connect to online, i can go to the homebrew app store, but it seems like my lan service had been shut off of that is even possible?
I have tried every method from other posts and nothing had worked ....
Can someone please help if they have been in a similar situation or knows More then i do.
Thank you
