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 everyone, I have studied the entire Internet and could not find 50% of the save for Zelda TOTK, on almost every forum I see 100% with a bunch of everything, but nowhere are there the usual saves of players that they passed themselves without using cheats, etc. After reinstalling windows, I lost my saves, I completed 3 main quests and opened the entire map, I'm not interested in playing when I have everything.
I use YUZU and the version of the game is not important to me, please share the saves if you have them, or send a link if you came across them earlier, I am in complete despair ((

Try one of these. These are my first 3 saves I have backed up. Not sure when I did what but I'm pretty sure I did towers first, ignoring all main quests and side quests.

Hope this helps.
