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.

Strange battery behavior (Rebug SwitchME)

I did the 7 wire install following this instruction (mattytrogs, i can't link internally because i have under 5 posts. i would understand that with external links, but internally? really?)

Flashed (for SwitchME, latest)

Part 1 - DUAL-BOOT (modified UF2 bootloader)
Part 2 - Switchboot_UF2 latest (CTCAer Hekate mod)

Now my girlfriend has discovered the Switch for herself and she plays longer sessions (2-3 hours). At about 40-50 percent, the switch simply goes off, with a battery warning symbol (not with a warning like you know at 10-8 percent on OFW).
Now I assumed that the battery had been incorrectly calibrated. A battery pull confirmed this to me, because after this the battery only had 5 percent instead of 50 percent. I had the battery fully charged. I did this several times, because the switch goes off again and again, especially when I don't charge the switch. today the battery showed 60 percent, after a battery pull only 3.3 percent.
the battery life is actually okay, but i don't know why the switch just goes off. after a battery pull and a charging cycle and a direct draining everything works fine.

Any ideas how i can solve the problem permanently? the battery cfg fix (if i start the bootloader from the switchme, i.e. without sd card) doesn't work, after a reset the percentage display remains faulty. I can't use the battery gauge fix at all, it always tells me to charge the battery fully, even if it is full. The battery still seems ok from my point of view, because the battery life fits normally.
