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.

mig switch not working/updating??

just got my mig switch and followed instructions to the T to update it and all im getting is a red light and then a message saying cart not recognised, all im trying to do is update it to the latest firmware, it says it should flash blue when...

Is there homebrew that would make the Switch Lite register itself as a wireless controller for local co-op?

Sorry if that’s phrased a bit weirdly, but basically, I want to play local co-op on my switch lite. Although, it needs two wireless controllers to do that. I have one, so is there homebrew that would make the Lite itself the other controller or read itself as a wireless controller?

Good question! I also would appreciate to be able to play NSMBU Deluxe 2 player mode using only a wireless controller but it seems impossible as the game doesn't detect the controller built into the lite along with the wireless controller. I have read someone saying that Lego games are capable of running the lite controller + wireless controller in local multiplayer.
