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 this had been happening before i migrated to an 256GB MicroSD, but for awhile now i have not been able to use USB Installs with either Tinfoil or Goldleaf (and im not sure how to setup FTP Installs) but when i plug in my Switch with Goldleaf or Tinfoil open Device manager Instantly shows an "libnx usb comms" device with a Driver Error.

i'm using Windows 10 Pro 1903 (i know im dragging my heals on updating) if it makes any the difference.

yep, installed the correct driver (libusbK), it did work for awhile bbut im not sure what changed to break it in Windows 10 @_@

[Edit: tested w/ my old Windows 7 Machine, Same effect, "error 10: the device cannot start" so its something about my Atmosphere/install of Tinfoil & Goldleaf
