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.

Alright so there I was playing botw mobile style off and on for about 8 hours plugged in about 80% of the time when out of nowhere

Error Code: 2162-0002

Had to turn off the switch and start her back up, within 5 minutes the error comes back up. So I turn it off wait about 10 minutes boot the switch back up and now it completely refuses to even see wifi and the connection with the joycons is absurdly spotty unless they are attached ofcourse.

So I shut it down and wait for an hour to let it completely cool down. Haven't had the issue since and wifi is working again, but I also haven't had such a long gaming session.

Looking up this error tells me nothing useful other than if it continues you will need a replacement. As far as I can tell from the behavior it is most likely an overheating issue.

So anyone else run into anything similar yet and if so have you come up with any other solutions.
