i did do all of that but when i launch mario kart 7 and go to online multi, it says its discontinued even though i set my pnid on my 3ds but i meant how can i tell if i am using pretendo and if its working.=
@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)
