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.

Hi guys after formatting my SD due to corruption in fat 32, I reinstalled all the games I had before but I'm unable to reinstall some games like just dance 2020, YouTube, super mario party..
I tried to install it through gold leaf and through awoo installer but without success.
Why do I have this problem? How to resolve it?

My guess is that kip1patch=nosigchk is missing in hekate_ipl.ini

I had the same problem. I don't know what is happened, but I solved formatting all data on the switch. If you wanna try, backup ALL your nand first, of course.

I resolved deleting all the folders except for Nintendo , bootloader and emummc; then installed nx-atmosphere and loaded into switch folder hbgstore(github). Installed tinfoil and enjoy download and install all the apps from the switch without using my computer.
For installing mario, Zelda,p ECC.. games I download it from xci and install it with awooinstaller
