Thanks for the mention of capitalisation - none of the videos or other help has mentioned that (I kept downloading skins, moving cart to DS, booting, hitting select to find no change - frustrating!)
@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)
