Embedded Update has been explained already in comments below. There's no update/dlc for the EU or NA versions of the game either in the No-Intro - There is no 6160 for Welcome amiibo for North America in the No-Intro database, so it will not be added. There is no DLC in the No-Intro CDN files, so I can't add it. It's called Layton Kyouju vs Gyakuten Saiban. under specific - The Update for Professor Layton VS Phoenix Wright is there for the Japanese version. The earlier updates are there for preservation purposes and for people who want to play PvP games like Super Smash Bros. cia it will have a different CRC32 - Most of the time you only need the latest update. There is no way to create 2 identical decrypted. Also, decrypted set will never be available, because the hash for decrypted. So I have no way to create the cia files anymore. Then No-Intro datted the files in the CDN - Update will be added - No-Intro has not shared the files for anything added to the 3DS CDN in 2022. Maybe say which file? I don't think any files have - They were posted on archive org at some point.
