i found out how to do it if you have digital x and y, you have to go to systems settings then go to data management then go to 3ds then software then press pokemon x or pokemon y after that press delete then it'll ask if you want to backup your save file, could someone copy their digital save...
@K3Nv2 I got some cheapies at wallys, that are pretty good, already have lost a few expensive ones (one falls out and gone, can't find) while cutting grass so bought some cheap ones, and of course never lose these cheap ones. (Cheap meaning only $35, compared to air buds which I only have 1 of 2 now)
