Very complicated story but here we go...
I have had a 3ds XL for sometime now. About a year ago I got a 2DS with Pokemon X installed and I got Pokemon Y with that club nintendo promotion awhile back. Now I have a main 3ds (The XL) with all my stuff on it. While on the other hand I have a 2DS with just X and Y on it. I want to get both X and Y to the main system. Is their a way to get them over to the main one, maybe using a complicated SD card trick? I was also wondering, if I were to a get a New 3ds XL could I take both the main and the pokemon system to merge on to a new system if I get one for x-mas or something?
