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.

Fantasize about the perfect fe3h mod/hack with me

My concepts so far:

Class changes

White Heron Cup competition open to all

Including allowing units such as byleth, manuela, shamir, catherine, etc to compete in month 12’s White Heron cup.

Dancer outfits are already available to forcefully put on every character, so I know the models already exist.

Gender unlock on all classes.

Such as pegasus/falcon classes. Such as gremory and dark mages/bishops. Hero/brawling based classes(including war master).

S-supports and paired endings

Give byleth unlimited same sex options for S support and goddess tower.

I am aware that same sex options are available by exploiting your save to have a temporarily included opposite-sex byleth during the final month. I know the goddess tower scene uses your same sex byleth already, even with this exploit, the difference in making this into a mod or hack is that it would not be an exploit but instead an already allowed option.

Give byleth edited S support photos for each gender with every character.

Examples from fans have been already made: Dimitri, Claude (I am a new user so links cannot be shared but PM me if youre interested)

Allow for the “closest allies” section in the roster’s character information to be an expandable/collapsable list that writes out all allies they have support points with.

In this expandable list the support points would be blatantly stated (in numbers “x support points”) as to leave no confusion.

NG+ Journal Clothing/Appearances

Allow for more customization with the character appearances controlled in NG+’s journal.

The customization would include “hair” for each character (similar to how it is for the Lords) where you can choose post-pre timeskip hair styles. This would be including listing dorothea’s hat as a hairstyle. Including byleth’s hair styles. This would NOT change the profile picture next to dialogue boxes.

The customization would include class-specific clothing being an option (it would be fine if this only became an option with the mastery of that class) even if the character was currently using a different class
