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.

SD Card not showing Switch Oled with Android

My SD Card stopped working twice. Ive already ressetted once, over all it took me 4 days to get all the downloads on it and setting up the emulators on Android.

My set up:

Switch Oled : Picofly
SD Card: 512gb (Brand: Amazon)
SD Card Format: Fat32

I created Android with partitions in Hekate. Ive pulled alot of games into the sd card using the Android USB, it works well. When I got to 1-2gb left on both partitions, the SD Card had issues with the Android USB where I can no longer drag files to the SD Card. So I took it out and put it on the PC to drag a file over, it worked. I was able to drag an APK file over but right after I eject and place it back in the Console, the Console no longer recognize any SD Card being injected.
So I took and put it back in the Computer and it tells me to “for mat it” which I refused. The PC prompts for me to format the Android partition everytime I put the SD card into the PC, but now it can no longer read any partitions on it, it just prompts me to format it and doesnt show the volume anymore.
I tested it with Mini Patition tool, I can still see the partitions and I used a scan test for failure of disk and there wete no errors, its without issue.
I reckon it has something to do with the Android partition ad this has happened in the past.

Does anyone have any answers to remedy this and is this an occasional occurence for those who uese Android partitions on the Switch? I am using Mini tools to recover the data right.
