Since my 3DS has decided to no longer work, I cannot dump the system archives (which I believe is needed for Miis to work) by normal means. I however always had a habit of regularly backing up my NAND and having a dump of my bootroms, otp, xorpads, SD card etc. So is there a way in which I can extract the system archives without my 3DS?
In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.
Sorry for a waste of a thread. I discovered using Ninfs, you can explore the NAND and copy over the necessary files.
