After I found out about the region-lock on the Nintendo 3DS, I wondered if an SD card that the 3DS uses to save the game data on is also region-locked.
For example, can you use an SD card that is purchased in Italy in a 3DS that is purchased in Japan? Or can the SD card be used only in the same region as 3DS?
I don't believe it is also region-locked, but would like to know definitively before I buy a new SD card.
