Any way to transfer Swapnote/Nintendo Letterbox letters over to Citra?

Hey, so I’ve been wanting to take a look at my old Swapnote letters, but since there’s no way to read the old files a la Flipnote Player and 3DS capture kits are so hard to get ahold of I figured Citra would be the best option. I then found their location in the SD card’s extdata folder, so I dumped my save file and pasted both folders into Citra’s emulated SD folder, but the letters didn’t show up in the app itself. Am I doing something wrong or is this just plain impossible?

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.
