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.

Author Notes: I am linked to the Asian store Play-Asia, because Nintendo Japan only puts Japanese images in its exclusive multi-language Asian games

1) Super Robot Wars T (Currently only physical version, in digital they took it away although when I checked for the first time if it had the language, my guess is that they realized that people in the West were buying it and there are people from an anime of magical girls with robots that It was very popular and is licensed by several companies in the West I speak of Magic Knight Rayearth)

2) Super Robot Wars V in Nintendo Japanese e-Shop and Playasia

3) Super Robot Wars X in Nintendo Japanese e-Shop and Playasia

4) SD Gundam G Generation Cross Rays in Nintendo Japanese e-Shop and Playasia

5) Kamen Rider Climax Scramble Zi-O in Nintendo Japanese e-Shop and Playasia

6) Kamen Rider Memory of Heroez in Nintendo Japanese e-Shop and Playasia

7) Olympic Games The Official Video Games Tokyo 2020 in Nintendo Japanese e-Shop and Playasia (Probably this will cease to be exclusive to Asia at some point, it is developed by SEGA. although its controls are worse than the Mario & Sonic 2020, I play the demo available in the Japanese eshop)

For now I leave the list here, the internet connection got too slow for me to continue. If anyone has any additional information. I will add it in the next edit of this topic. I could also notice with Play Asia that this list also applies to the PS4 with the physical versions.
