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 All,

Wife new to video games, got a switch with Mario Odyssey, she got addicted an 500+ moons later she is looking for another game.

I thought about BOTW but perhaps it would be too much given the depth? Thoughts for alternatives? Preferably a first party title.

I'd go for a 2d platformer like yoshi's wooly world or new super mario bros.

My wife is also pretty new to videogames, got her Switch and has been really into Octopath Traveler (loves RPGs), Breath of the Wild and Kirby Star Allies. She also loved Pokémon Let's Go and Yoshi's Crafted World.

I have been playing "Mario + Rabbids: Kingdom Battle" and am loving it so far. It's quite easy to understand and it's mechanics are really fun, the graphics are also very nice. Totally recommend it.

Yoshi's Woolly World is not on the Switch. Yoshi's Crafted World, was hooked from the start till the end.
Also has co-op

I don't think BOTW would be too much. You can kind of make the game whatever you want and if she loved wandering around and collecting moons, she'd love BOTW
