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.

Launching HB from switch menu

Hey, I want to launch Solarus and SMW from the switch menu - I've put both the Solarus and SMW folders in the switch folder (they both play fine if launched from the HB menu), and then installed the .nsp's. Neither are working when I'm trying to launch them from the main switch menu through the icons installed via the .nsp's. Any advice? How can I get these to work without going in to launch them through the HB menu? Does anybody know how it works? Say, if I put the .nro files onto the SD root, could that fix the problem? What file path or paths does the switch take to find the necessary files to launch games from its menu? I feel if I knew that, I could move a few things around on my SD card to get this to work.

I have other HB games installed - Half-Life, for instance - that do launch through the Switch's main menu, although these are compiled, structured and installed differently than Solarus and SMW. Very interested to find out how this all works; why Half-Life launches from the main menu but Solarus and SMW can't.

Thanks everybody!

Edit: I just posted this, and straight away thought to ask AI for the answer. Will keep anyone updated on how it replied if you're interested! About to start a chat with ChatGPT about this, unless anyone has any suggestions for other Ai - would be interesting to see how they reply and if they can fix the problem
