I recently bought a used slim PS2 (70xxx series) and I was interested about online capabilities. The problem is that it came without the internet connection disc. Is there any way to get it for free? Anyway, I don't know how many online content is available, so should I bother getting it?
Contact Sony Customer services and they send it out to you for free. Online gaming isn't fantastic on the PS2 but I've had my fun moments.
Most (if not all) online game can make the configuration file as well. I had tons of fun playing Midnight Club 2 and some other games. HAven't played online on the PS2 for a while though.
