I believe you have missinterpreted the friend code system... there is typically online "matching" service, that will allow world wide competition, but no chatting or "online status"... with prime hunters you are able to create a "rival list" of people you've played before and see online status of them... and then friends who you get to see status of and chat with... never used the friend code and have played online with my DS plenty.
