yes you can. if you have wireless internet (or somehow conect your wii to it) if you want ann exxplanation plleasase tell me becaauss this keybboard is to annoyinng to type with
fire, now that i have a normal keyboard i will explain. after you make sure you have what i said. you have to go to the wifi option in the game (down left side if im not wrong in the menu). then just wander there alittle and eventually (there arent many options there) you will see your friend code. if you give someone your friend code and put that persons friend code as well you will be able to see if he is on, his username, the connection etc. if he is on you can fight him. also, there is an option to play with random people kind of like in ep.... but it never worked for me
