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 have my patched Switch on 4.0.1, and had been using it with 2 SD cards, one with an "OFW" to go online, purchase games etc.. and the other to play backups, mod games, etc..

I have used it that way for a long time, now self hosting Pegascape when switching from one to another SD card.

Yesterday I was having problems with some games crashing on my second SD so I decided to manually update hekate and atmosphere. So I copied some files to the SD card and after trying to boot to CFW using Pegascape nothing happened. When I press the power button after tapping the textfield and waiting 3 seconds my switch just turn off it's screen and stays there instead of booting to CFW or Hekate.

If I press again the power button the switch screen turns on and shows the PegaScape screen with the alert, but naturally the only thing I can do is force turn it off by pressing the power button for 15 secs..

After trying a lot of things I decided to backup my emuMMC (in fact all my SD), and trying to start from scratch.

So I formatted my SD card to Fat32, downloaded latest version of Hekate and Atmosphere, copied the files to my SD, loaded Pegascape, but again, nothing happens after tapping the textfield, waiting the 3 secs and pressing the power button.

The switch just turns off the screen and can be turned on again by pressing the power button.

I'm missing something? My other SD with hekate, atmosphere and all the stuff to go online, works ok.. Also tried using another empty SD to use for backups but had the same result.
