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.

Hi.

I am planning on getting a Sx Core modchip. Currently have a Switch Mariko.

Do I need Sx core v1 or v2 ? I really cant find any information regarding this.
And what is the difference ?

Thanks for any help.

You need SX Core/SX Lite since your motherboard is v2.

There is only one SX Core version, maybe you mean the cables, which are labeled v1 and v2. In your case, you have to use v2, v1 is for unpatched and Erista models.

So here is the weird thing, I have a V1 I assume because the sx cable matches with the V1 on the switch and I try to boot up just shows blank screen light on chipp flashes blue then turns green. Screen backlight turns on but no image or anything. This is with SX core installed tried two different chips same problem
