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've been wanting to work on my port of Mega Man 2 that I made with Petit Computer, but the main reason I was able to get that made was because I could make most of the assets on my computer, convert them to the proper Graphic Pages the program used, then scan them in for use. With FUZE4, it's generally tied down as far as how to make assets, which unfortunately is with its own built-in programs, which are very limited. So the idea was to possibly hack the saves (which is where the custom data like the programs, media, etc are stored) and replace blank data I created in there with stuff I provide externally.

For anyone that has looked into it, is it simple, or complex to deal with?

While I understand that any save hacking is not considered 100% safe when it comes to banning, FUZE4 isn't really a game by nature where hacking can provide a means to cheat against others, but a program to make things like games which one can share via friend codes. I know there's some program that can help clear data to reduce the chance of a ban from alterations made, but I dunno.
