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 am curious about this, Has there actually been any proof of a dock being the cause of a switch bricking? Also were the docks being used with cheap grade third party power adapters? I've searched for proof of this on youtube and the 1k+ recesses of google results and come up empty on seeing it happen or of the actual circuit boards of the broken consoles to see indications of surges. This seems to coincide with the release of nintendos 1st quarter sales totals for the switch but I won't delve too deep down that rabbit hole. Hate to say it but proof or it didn't happen like you claim it did.

I should stop trying. Some research shown that Nintendo Doesn't follow the USB-C high voltage standards and that's causing the issues. Just normal USB charging won't be an issue. But when you use a 3rd party dock, they use a different way of charging the Switch. The same issues happens when you try a 3rd party high voltage charger/batterybank directly on the switch or dock. Bot of them can die on you.
