So if i purchase flash card for DS and put, lets say, pokemon platinum on it, will i be able to normally use new shiny WiFi features or do they require some kind of code from game box to be able to play online?

Please excuse my English, i'm from Finland (ooh look, a polar bear just passed my window)

Yes, online should be able to work flawlessly, depending on the game. PKMN Platinum works just fine on WiFi (I'm on it all the time). It varies between games, but once again, they should work 100%.

I'm Canadian, and being Canadian, we also have polar bears (ffffff it's chewin on my phone line again).

Oh, you too?

Damn, those polar bears are causing some serious trouble

I thank you very much for answering so fast!

Yeah it sucks. In fact, I've frequently told that polar bears love DSL lines.
