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.

Pokemon Shield

Honestly....it was a day one buy for me. I was so excited. And then...that happened. So now I'm waiting to see what happens. Then I'll see if it's worth 6500-7000 yen or not. If I buy it... I'll get Pokemon Sword.

My last Pokémon game was Pokémon Y. Gen 7 didn't really appeal to me.

Seeing that this is the first HD generation, I'll probably buy Sword.

Gen 7 was awful and this looks less technically competent than the N64 and Gamecube games. I'm not buying something just because it has "Pokemon" on the box. Can't wait for Super Duper Sword and Shield to come out next Christmas and have "has all the Pokemon" as a selling point despite currently trying to spin the opposite as a positive like with Fallout 76 and NPCs.
