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.

Script to easily set up Android (Oreo or Q) + L4T Ubuntu + CFW + EmuMMC on one SD card (New)

Hello, i've made a new, more easy to use script to install l4t, android, emummc etc.
Supports to install L4T Ubuntu and Android Q to eMMC, supports to install up to two Android images (Oreo+Q or Q+Q), L4T Ubuntu and up to two EmuMMCs to SD.
Also gives you the option to backup/restore to/from image, to download the images while running the script, to fix MBR in case its broken and some other stuff.
Just run the script, the menus should be more or less self explanatory, if you have questions feel free to ask.

Please keep in mind that Android Q has not released yet. Please do not ask for prebuilt images.
Instructions to build it yourself can be found in the switchroot discord. If you cant build it your self for whatever reason, just wait for release.
Currently it is not really usable as daily driver anyways.

It is not 100% finished, i am going to clean up the code eventually and add a more elaborate readme.
~~If someone feels like writing a nice readme, feel free to send a PR~~
