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.

I’ve seen this chart. When the reboot fails I get the solid cyan color (FPGA error) so I’m not sure what it means. I have also updated to the latest version of the firmware and still getting the same issue.

I don’t think it’s a problem with the soldering since the chip works 100% of the time on cold boot, and fails (almost) 100% of the time on reboot.

it’s not really a big deal since I can just power off and back on easily enough if I need to reboot but would be nice if there was a way to get it to work in all cases.

That interesting mine work fine rebooting from horizon os and coldboot

So I got mad when my OLED wouldn't glitch, I'm pretty sure it's because of the dat0 adapter. I shook the switch like mad, rebooted, and BAM green light every time now....

Not the best solution, it feels like my father hitting the tv to make it work.
