So a couple of weeks ago I got the New 3DS XL. I did the wireless transfer with my old 3DS so that my games and save data were on there. I used the 4gb SD card that came with the system. But soon I began running low on storage (especially with the smash updates) so I had to delete and create a bunch of save data for my stuff. I found a 16 gb micro SD card lying around so I put that in and I downloaded Pokemon Rumble world and I got far into the game and I even spent some money on it. But the game doesn't support the whole save data backup thing oddly.
So does anyone know how I could transfer all my save data/games from my 4 gb SD card without losing my progress in Pokemon rumble world on my 16gb? I've searched up this topic on the intern and it seems people have similar problems. Except it seems complicated and like I said before Pokemon Rumble world doesn't use backups. If anyone could help me out that would be great
