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.

So I just updated from 4.1.0 to 5.1.0.

Had an issue where homebrew was not showing, so I did the windows fix here

Now I can install some nsp files but not others, mainly botw (get black spinning icon). I also noticed it seems to show "failed to register" message".
I'm using tinfoil (tried booting from hekate v4 and RajNX).

Any ideas?

Updating my own thread again lol, maybe it will help someone else.

So I deleted all the games from the switch, including saves, then formatted the sdcard (Samsung EVO 128Gb) from the switch itself. Copied over all files, back to switch, homebrew not showing.

So rebooted switch into hekate 3.2, i think it's tools then there's an option for "fix all sd card attributes", I chose every sd card file.

Rebooted and now game is installed and working (i used SXOS this time but probably another cfw (rajnx/reinx) and tinfoil would have worked).
