Pokemon X and Y will take up 1.7 GB of SD Card Space
So you’d better have some room left on your SD card, since 1.7GB is equal to about 15,000 blocks. That’s no small amount of space at any rate.
What do you think? Are you going to buy Pokemon X or Pokemon Y as a digital download from the eShop? And if so, how you going to find the space to store it?
