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,

I have been playing mario 3d world on the switch with my nephew for some weeks now. I noticed an input lag while only playing in multiplayer. first I used 8bitdo ds4 + joycons. later switch pro + joycons. some times we played with 3 person or only switch pro and ds4. for some time with missioncontrol with wii + nunchuck and ds4. well the input lag was always there. I always thought it's some bluetooth interference because the joycons always had some kind of disonnects in my launch switch.

not sure if it's 3d world only problem, need to test it more. I kind of just accepted that input lag. but now the baffling thing. I got an wired xbox 360 and sys-con and even that has input lag while in multiplayer.

(before I forget, it's not caused by the death animation of another player, it's enough to feel the input lag when both players are running in a cicle)

edit: I just tested yuzu. it's the same thing. funny thing is, I tested some configs. if I disable the gyrosensor, the input lag is gone. even if both controllers on yuzu doesn't send any motion data.
