Can the 2DS XL play 3ds roms? If so, I'm assuming it would need a flash card. If so, what flash card would be used? I just realized that this console is not even available yet. How about 3DS XL? I just read somewhere that 3DSXL can play 3DS roms but has to be under a certain firmware level? What would that be? What would be the proper flash card to use? Thanks.
