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.

Cannot manage to restore my Pokémon Violet save

Hi everyone!

I've been playing Pokémon Violet on Ryujinx, but now that I have a Switch with CFW, I want to continue my adventure on the go

So, I've taken my save coming from Ryujinx
On the Switch, I launched my game and played until I could save, then I tried to restore my save with JKSV, but it didn't work, when I launched the game it was like there was no save data.
I tried the same with checkpoint but with no success. Am I doing anything wrong?

Thanks for the help!

Well, I find it by myself I guess.

If anyone encounters a similar issue, there is no main file in the root of the save for some reason. And that's the save the switch is loading, so you will have to copy the main file from 0 or 1 folder (check with PKHex which one to get). And now you can restore this save and you're ready to go!
