How do I play PS2 games online with my 80GB PS3?

I created the internal memory card I downloaded the PS2 System Data and I can't figure out what I do after that. I want to play Star Wars Battlefront right now but later it will be Heroes of the Pacific and Midnight Club 3. When I go to the online connecting options I get the same as the PS2's. And it doesn't even give me an option to do wireless.
