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.

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...

Hardware Do you think Switch would have been even more succesful if it had an external gpu?

Honestly... I don't think it would've been good to even hint at eGPU Dock at launch. If they did, AA developers would bank on the dock being available and pressure users into using it all the time if they don't want a shitty experience. It would've added cost if it was included, and developers may make it into requirement if it wasn't.

That being said, I do believe it may be possible in one form or another, and Nintendo may launch one in the future. Type-C does have alt modes, and Nvidia has the technical knowhow to figure out how to make a eGPU data passthru for it. It seems to be theoretically possible based on what we know, it just depends on Nivida and Nintendo developing the Switch from scratch to support it as that's not a feature they can add in as an afterthought well.
