I have the save but it doesn't show up. All my others do (I took them from my old SD card and put them on my new 3ds micro). Any suggestions?
1. Your 3DS Firmware version
2. Your N3DS Firmware version
3. Is your game a 3DS-rom/CIA-installation or retail-cartridge?
4. How did you transfer your saves etc.?
5. Did you use Nintendo transfer software from the system settings?
6. If yes, do you still have your saves on the old 3DS?
I'm asking the last question because the Nintendo transfer software asks you at the end if you want to delete your old SD-content.
In the end it's like this:
1. For
3DS-roms you should have a 00040000000EC300.sav in the root of your SD-card. Copy it to the new SD and you should be good to go. Easy as that.
2. For
CIA-games you will have a 00040000000EC300.sav-file as well, but you need to do something else. You open up SaveDataFiler and in the "User"-tab you look for "00EC3". You can check the ID yourself on

Then you export the save-file using the
Y-button (look at the top-screen) and then the
A-button (for confirmation). Next you put the SD in your PC and there is a new "filer"-folder on it. Copy it to the new MicroSD.
On the N3DS open up SaveDataFiler again and go to the "SD"-tab.
there you will see something like:
