I've been seeking an answer for this for some time, but the internet seems to be fairly ambiguous when I have asked in the past. Does anybody have the technical knowledge to help me out? Recently, I installed Luma 3DS custom firmware. I am running 11.2 Emunand on a 4.4 sysnand, both are Japanese firmwares on an original Japanese N3DS LL. All games seem to run perfectly fine, and I have accepted the EULA agreement for other countries via config. However, I have encountered several issues. 1) I downloaded a US version of Fire emblem Birthright, with matching Birthright US DLC and updates, yet they do not appear on my game. Why? 2) Majora's Mask 3DS specifically shuts my 3DS down, and restarts it, saying that there is an error with the SD card after booting. It is the only game that does this. 3) Super mario maker and Bravely Second both will not appear in English, despite being downloaded as a US file. Why? Extra information: I have examples of many other fairly new games, such as Animal crossing: welcome amiibo, Super smash brothers, xenoblade chronicles and more, which work correctly online and with their DLC, in the language native to the ROM's region. Why do the games I have listed not work? Does anybody have any clues, or suggestions? I'm really at a loss with this.
