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.

okay so I just bought portal and portal 2 collection thingy, and I was looking to see if there were mods for this and well... I stumbled across the "Bringus Menu" for portal 1 and 2.

Issues is... I can't for the life of me figure out how to install this, NXDumpTool is broken and tosses an error when I follow their Youtube Tutorial..., How do I get my hands on the game.zip if the dump tool is busted???

I looked into "nxdt_rw_poc-.nro" supposedly a "work around" for NXDumpTool, but it don't seem to have the same options i need, or the terminology is confusing? I unno what I'm supposed to dump!

I also have DBI and GoldLeaf....can either of these do this??

Also looked into the side-loader for Portal 1 and 2, but there is no str8 forward tutorial on how to use Bringus Menu with it.... just "verified" it works... wish someone would give a walk thru of this!...

Any help or Ideas would be appreciated!
