Exactly! But if you want to play ONLINE nowadays (after Nintendo WFC shut down) on these systems, just use Wiimmfi. If you want to play any game other than the Pokémon Gen 5 games, use any DS with open or WEP security on a network, and use 164.132.44.106 as the DNS. If you want to specifically play the Pokémon Gen 5 games, you must use a DSi or later, and set the same DNS in System Settings. This will automatically connect you to Wiimmfi (for free!) and let you use ALL of the features that were previously available. (except Game Link in Pokémon Gen 5, as that website is gone for good, with NO replacement)
