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.

Hardware Joy-Cons will only sync to the console if I pair them through the Sync button

Connecting both Joy-Cons physically to the Switch Joy-Con rails will display a "Paired" message once, but the Joy-Cons won't work wirelessly afterwards if I remove them from the rails. Only way of making them work wirelessly is to manually sync them through the Sync button on the Controllers option. Any idea why this happens?

Make sure the white and black cable ( wifi and bluetooth) sits tightly on the pcb IF you have opened it up recently

@Gabriel2Silva were you able to solve your problem? I'm currently facing the same issue with my right Joy-Con. Did yours also give up connecting after one cycle of the LEDs? Mine only tries to connect for an appropriate amount of time (cyling through the LEDs multiple times) if I long-press the sync button, but that will, of course, only sync if I'm already in the controller pairing screen. Waking the Switch up remotely is impossible this way.
