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.

I'm trying to make custom icons for all the games on the console, including the ones that are installed on other sd-cards, since they still show an icon in the "all games" list and I don't want them to look out of place.
Can someone tell me where on the console these icons are saved? Goldleaf is showing the icon thumbnails if I hit console-contents -> other, but says there is no date when opening them.

Thanks in advance

You can extract them with DBI in Browse Installed Applications, though you cannot replace them that easily. You can use sys-tweak to replace icons.

Thank you for your answer, however DBI shows an error "Content meta not found" if I try the dump to sd card option. Exposing contents via MTP crashes atmosphere too.

I have decided use blawar’s nut software for the time being to download icon links from Nintendo’s cdn and use jdownloader to batch download all the icons I need (they’re also 16 times the resolution)
