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.

My kids' console is running AMS 0.14.1/fw 10.1.0 and he's dying to play some games with his cousin over local wireless play who owns an unhacked console running official FW.

Are there any issues with a hacked console playing local wireless with an unhacked console?
Let's assume the official FW is also 10.1.0 and the game versions are identical.

Thanks!

There are no issues, unless you have cheats or sys modules that get in the way.

I was under the impression some games (like Animal Crossing) would not allow this

The last I'd heard on the topic was that a linked account is required, but I can't confirm this myself (I play AC on OFW).

Works fine. I play it all the time with my son, and he is on an unmodified system. I even use his switch to update my game with the update sharing feature built into the switch
