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.

So recently I've been installing .nsps my Switch (running Kosmos 14.2) using Tinfoil and things were going smoothly. The only game though that I'm having trouble with is Super Smash Bros Ultimate. What absolutely p's me off about the situation though is that it's already worked once. I ended up deleting all my games by accident while trying to fix an unrelated error, but before that I tested the game and it worked perfectly. I redownloaded all of my deleted backups and they all worked except for SSBU. When I try opening it gave me the message that you saw in the title of this thread. I reinstalled the game several times now. I used different files from different sources. I have the required patches installed. I checked for corrupted data and found nothing. I deleted my save and the software multiple times. I disabled archiving for my files. I turned my console off and on again. Nothing is working at all and the last thing I wanna do is reformat my card again and spend forever moving 70+ gigs worth of data back on to it.

I am currently at the end of my wits and am pretty p'd off at this point cause I just want this game to work like it was before.

So if anyone has ANY suggestions for how to fix this, I'd love to hear them cause I don't know what else I can do.

[Edit] Forgot to mention that yes my SD card is formatted in Fat32
