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 want to develop a homebrew to control drone, cause in my opinion Switch is a perfect fit for that. But an unexpected problem occurred when I tried to connect to drone's WiFi LAN. Switch doesn't allow to connect to a hotspot which don't have access to Internet

Is there any solution to bypass that cursed connection test? Ideally, I want to connect to a hotspot by using only libnx without user involvement.
Thank you

You need setup DNS server and http server (maybe telnet server will work too) in your local network (drone's network

). Set this DNS in switch wi-fi settings manually. At DNS server redirect query for nasc.nintendowifi.net and ctest.cdn.nintendo.net to your local http server ip. Create any html page (even blank) in http server root directory.
After this you should able connect to local hotspot (last tested in 6.0.1).

My english is not very good, sorry for this.
