So I just helped my girlfriend downgrade to 9.2 (everything went fine first try, old3DS) and set up emunand using Emunand9tool, and the December 5th RXtools nightly. everything worked fine, all her games and everything showed up. She bought a new SDcard today, and again using Emunand9tool we formatted the fresh, never before used sdcard. I then copied all the files from the old sdcard to the new one, and used Emunand tool to inject the old emunand into the new sdcard. However, now when booting into emunand none of the games show up, and fbi fails installing due to "database does not exist." Inside the "Nintendo 3DS" folder are now two more folders, a new one, and the old one I copied to it. Should I have copied the "Nintendo 3DS" folder to the new sdcard before formatting emunand to ensure the nands were properly linked? EDIT: I solved the problem by just deleting the new folder emunand9tool created.
