Question about save data in the 3DS

[Beleated_Media]

I can't find my copy of Pokemon X, and I was just wondering if the data is either saved onto the cartridge or the SD card.

It's saved on the cartridge if you have a physical copy.

It would be saved on the cartridge if it's a physical copy instead of a digital copy
