Do Nintendo 3DS Games Save to the SD Card/microSD Card/System Memory?
Nintendo 3DS
No. While some Game Cards do save SpotPass and StreetPass information to the SD card or system memory, game progress (levels completed, items collected, etc.) is saved to the Nintendo 3DS Game Card.
Note that save data for titles downloaded through the Nintendo eShop (not played on a game card) is saved to the system memory.
