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 all,

i dont know whats happening with my switch oled.

My switch oled works fine but sometimes it doesnt turn on. So i have to unmount the console, unplug the battery conector and plug it again , then console turn on. But sometimes when i mount all the console, it doesnt turn on and I have to unmount again.

I did my picofly installation and everything works fine, dat0 is working, etc, when i unplug the battery conector and i turn on the console i can see the hekate screen "No sd card", if i plug the micro sd card i can enter hekate or cfw menu, but if when finish mount it, doesnt turn on, sometimes yes, this is the 4th time I have to unmount the console, and now doent turn on when i install the case.

Of course, I dint did nothing in the battery conector when I installed picofly. I am using the cpu flex.

I removed my kapton from the rp2040 modchip and added insulating tape and now it turns on fine, but I don't know if this is a final solution, if anyone can tell me something...

Thanks in advance.
