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.

How i make my own custom Background

I take no responsibility for your switch if you follow this guide!

What you need:

- CFW on 5.1 (idont know if it runs with 6.0) with newest Layeredfs
- common.szs File (from a exist custom background mod, you will find one on my discord)
- sarctool - https://github.com/aboood40091/SARC-Tool/releases
- BNTXEditor - https://github.com/aboood40091/BNTX-Editor/releases/tag/v0.3
- Photoshop with Intel DDS - http://gametechdev.github.io/Intel-Texture-Works-Plugin/
- 1280x720 or 1920x1080 Background

First,

Install the Intel DDS Plugin and open Photoshop.
Open your wish background in Photoshop and go to "Save as"

Select File Format "Intel Textur Works DDS"

Save it will open an attribute window, choose the following attributes:

- Texture Typ: Color
- Compression: BC1 4bpp (Linear)
- Mip Maps: Auto generate

click ok.

Extract sarctool and put the common.szs file into the same folder.
Open CMD by typing in the path of Explorer "CMD" and press "Enter".

Enter the following in the CMD window: sarc_tool main common.szs

A folder is created called common.

Extract BNTXEditor and open it.
Select "Open File" and select the file "__Combined.bntx" (common\timg) from the folder that was previously created.

Select the "White1x1_180^r" DDS.
Replace it with your before created DDS from Photoshop and uncheck in the poping out window "Use SRGB when possible".
And safe it.

Go back to cmd Window and typing: sarc_tool main -o common-new.szs -little -commpress 9 common

A file is created called common-new.szs.

Delete the original "common.szs" file and rename the file "common-new.szs" to "common.szs"

Create on your Switch-SD-Card the following folder path: atmosphere\titles\0100000000001000\romfs\lyt
And copy the "common.szs" file into \lyt

And last but not least, start your Switch with newest Layeredfs.

Done!

NOTE: When starting it can come to an error. Then just restart again until the switch boots.
