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.

Hello everyone. I recently got an unpatched unit with neither bluetooth nor wifi working, it can't find any wifi network and joycons can´t sync wirelessly (neither in Sysnand nor emunand). I've tried several solutions, even a hard reset (with Haku33). Some posts suggest it may be a hardware problem with BCM4356 chip in the motherboard, however it seems that only solution is replacing this chip with another one from a working unit (apparently new ones won't work) which is not feasable for me.

At this time, the only solution I see for wireless connection to joycons seems te by an usb adapter like MAYFLASH Magic NS, but this seems to work for both joycons as one controller, and I would like to use both joycons as separate controllers for multiplayer or games like ARMS.

So, I was wondering if there's any way (via software) to use a bluetooth usb adapter for PC as bluetooth "manager" for the switch.

I know there are adapters for bluetooth audio like homespot, or adapters for controllers like the mentioned Magic NS, but they only cover one function, either audio or one controller, so, if using a bluetooth usb adapter is a feasable solution to have all bluetooth functions again, that'd be nice.

Thanks in advance.

PS I don't seek a wifi solution because of the LAN adapters, which are a solution I already tested to connect the unit to internet.
