just certain games work . so far theres S.O.C.O.M US Navy Seals , Tony Hawk 3 , Madden2003.
now that the adapter is out , more game developers should be making games , and im sure theres more than those three out right now. on the back of the game there are the little symbols for amount of players , what rating the game falls into and now the online multiplayer.
its a little box that plugs into the back of a PS2 and utilizes your curent (if you are online) connection. the box looked like it had 2 ethernet plugin on it . hmm now im really curious exactly how it works lol. i was hoping to get one for my birthday but now im going to have to hunt one down sooner
