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.

Hello all, Ive been looking around the forums and can't find a good answer to my problem (I may have missed it). I have an OLED switch with an instinct-nx chip. Everything works ok with my 128gb sd card. I decided I wanted to upgrade to a 1tb card so I picked up a silicon power 1tb sdxc card, when I try to use it in the switch I get a "failed to init sd card" error from the instinct chip.

Things I have tried:
- Formatting the sd card to fat32 and exFAT with 32/64 cluster sizes (i've used guiformat / easeus / minitool / powershell)
- hwtest on sd card finished without errors ( Writing speed: 32.6 MByte/s + Reading speed: 37.4 MByte/s )
- tried hotswapping card in hekate to get sd card info with no luck ( couldn't read it )
- tried booting into stock to format sd card, it reads that a card was inserted and asks to reset, and then on reset if I skip instinct screen to stock firmware it hangs on switch logo screen

Any help or suggestions would be appreciated, thank you.
