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.

Hey everyone,

I've installed (NSP) Pokemon Sword on my Switch and for the most part it plays fine. The issue I have is that when i'm in battle and open my bag the game freezes on the transition between the battle and the bag. It basically shows a white screen but the music still plays. The same thing happens when, outside of battle, I go in my bag and go to the key items section. I have the base copy of the game with no DLC or update. I had DLC and update but my cheats wouldn't work with the update so I reinstalled without all that. I've tried with and without cheats enabled. I'm on Atmosphere 0.19.5 with 12.1.0 firmware. Can anyone, PLEASE, tell me why the game freezes like that and how I can fix it?

Thanks

Edit: I've gotten a xci copy and that appears to work. The menu lags in coming up and exiting but it work. I don't know why the map versions I tried don't but oh well.

Mods, ok to delete this thread since the issue I have is resolved by switching file formats.
