Hi, I recently bought a new New 3DS so I decided to transfer my account to the new system. I was using the PC transfer method, everything seems like according to the instruction. My Micro SD card is now filled with the old system files but somehow the New 3DS could not read the data. It is filled with downloaded games, save files, ambassador program, etc. So right now I can't download new games (because my Micro SD card is almost full and can't delete it through system setting. Can delete from Micro SD management, but not sure which files to remove), I had a pokemon shuffle that lost its saved file. Luckily when I play my monster hunter 4, it still able to open my saved file.
Anyone can help me fix this?
