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.

Need your advice, switch not powering on. Now APU Heating rapidly after removing sx core ribbon with battery connected and pressing the power buttonmakes the APU heatup so fast. tested components using multimeter around M9, BQ, P13 no shorted capacitors..
Sx core installed.blinking blue light..then solid green. but no sx logo. doesnt show boot.dat eror even sd card removed.
i'm assuming something is shorted.. thats why apu is heating up so quickly.

switch unit is version 2
m9 - pin 5 3.3v
pin 6- 3.3v
getting about 4v on caps around BQ IC
no shorted caps around P13usb

any help suggestion to figure out whats causing the issue.. i swear..i just removed the sx ribbon cable to test if it still boots up normally or the capacitor is cusing the issue.
TIA :cry:
