None of the categories listed have any items attributed to them at present, which would make sense as the Virtual Console isn't yet a thing on Switch.
But will it ever become a thing? Could these references merely be a carry-over from the 3DS era, which has the exact same categories listed in its JSON? Or, if we're being really optimistic, is Nintendo planning on bringing the Virtual Console to Switch after all? Post your hopes and dreams in the comments section below.
