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.

Ok, so All that have tested Labo Vr Garage, there is some grate stuff there.

Few things i wish it had are

Sharing!! I mean come on, we can create all the cool stuff, but if i want to someone to try it, they have to go though all the work to wire it up...
Computer editor, eave if its just the 2D version, some way to simply the builds.

Started looking at the save files, LgcPlzFileSet[0-3].bin
They seem to hold the data for the corresponding pages of files, aka Page 1 is LgcPlzFileSet[0].bin and Page 4 is LgcPlzFileSet[3].bin

Some info form the help menu may help in decoding.

You can have up to 256 nodes and 256 connecting lines per file.
The max "cost" per file is 2000, and each node will change based on the nods setting.
You can connect up to 8 wires to one port.
Any connected Nodes are called a Bind group and only 32 nodes per Bind group.
The max chain of nodes is 16

My first gole is to find the file and page locations, so that one my be able to start sharing stuff online.
some sort of loader that would take a save and load a file into a corresponding page and slot.
