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.

Splatoon 3 Table Turf Editing?

i know this probably seems like a crazy topic to ask about due to the banwave that happened prior but theres something that i took notice on..
just like the splatoon 3 story mode, tableturf seems to be a game mode thats completely offline and stores its data locally on the switch rather than storing the data online like everything else. you can see for yourself simply by playing the mode offline. i was also able to extract my s3 save file and import it to another account, and the data that got transferred were again story mode data, table turf data, as well as my badge data interestingly enough, and that account is still unbanned to this day. (i've been playing on the account for around 9 months now)
so my idea is to see if its possible (with someones help since im clueless haha) to create and editor JUST for table turf, mainly to help with the level 999 grind and card sleeve collecting, and of course the idea is to test it on a dummy save file first and wait a couple of months maybe to see if its truly safe to use.
