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.

Extreme battery draining while in sleep mode?

Hello everyone,

I had the most bizarre thing happening to my switch for a couple of days: fully charge, the battery goes from 100% to 20%in sleep mode in a few hours. I checked with hekate the health of the battery, it says 4668 Mah, which is pretty close from the base capacity...

Is there anything that could cause that much battery drain in sleep mode in such a short time? Thought it might be my Hori Split Pad Pro controller, since the first hori gamepad joycons had some problems regarding that, but I took them away and same problem.

Also, there seems to be some kinda of graphical glitches in the battery power display: Like, I turn my switch on, it indicates 20% left, I turn it off and on again, and it displays 25%...

I don't particularily mind changing the battery, but if the problem doesn't come from there, might be for nothing...

If you have any lead, I'll gladly take it, thanks!
