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.

Pillars of Eternity Translation

Hello there!

I am trying to use PC translation for Pillars of Eternity on the definitive Switch version. I have succesfully extracted the game and from what I can see, the game has pretty much the same structure as the PC version. The only difference is, that the Switch version has all languages .zipped (as "Localized.zip"). For reference, I am attaching this picture - on the left is a Switch version, on the right is a PC version.

Somehow, though, I am unable to use the pc translation in the game: I have tried adding the translated folder ("cs" language) to the .zip alongside other languages (DE, EN, etc.) and I have also tried replacing the files within the FR folder (trying to force French to show my custom translation), but somehow the translation is not different. It kinda seems like the LayeredFS are not working at all (I am using latest Atmosphére 0.9.3).

Is there a way to check, whether the LayeredFS is actually doing its thing, or can anyone help?

Thank you!
