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.

Very much looking forward to this fix. I try if unlinking my other family accounts will work. Thanks for the update!

Me too! I’ve just about tried everything I cannot get the freeze issue working at all, it happens with any linked account not just two consoles, it freezes soon as you set up your Nintendo Account on the console, it’s a shame because at the moment I keep having to use all my carts and not my backups and that’s what I want to use. I also get very sick & tired of everyone answering me all the time on how “you shouldn’t be using xci’s online anyway else you will get banned” I already know this information thoroughly, if I didn’t know this already then I wouldn’t be asking the question “when will this be fixed”. I have sent several emails to TX on this, if that gives you a little bit off hope.. if you ever find a solution buddy please let me know asap.

Edit:
The only thing that might work is if someone created an ips patch similar to Atmosphere patches that updates the 9x firmware with full compatibility for xci emulation now that might work. The problem was created when Nintendo updated the switch to 9x firmware which changed the gamecard which also changed the xci emulation for online use.
