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.

Just wanted to record what I went through with my switch so that it might help someone in the future. I was going through some odd corruption of the SD card slot. I typically run atmosphere and started having issues with my SD card disconnecting while playing. So I replaced the slot as many guides sometimes tell you to do.

I continued having the same issue with less frequency but then it got from bad to worse. I thought it was loose pin because it was okay if the console was face down horizontal and that helped but that eventually stopped working. Then the SD card stopped working altogether.

I noticed that the slot worked because when I inserted my SD card it prompted an error posting this after the fix so I cannot say what error it was. Eventually I thought maybe something was wrong with the software that effected the slot. I wiped the console and that solved my SD card issues.
