    Need more info:
    From you question, i assume you downloaded the rom and tried to go online.
    If that is right, you need a header to inject into the rom to play online.
    You can use a public header and get band from all online services. (just saying this now so you would know)
    Or you can buy some cheap $5 or $10 game at best buy and extract you own personal header to play online.
    Search the forum for more info

    If you by chance downloaded the game from somewhere, you will need a header. If you can't find a header, I recommend converting your game to CIA format, no header required. If you're using your own legit copy, just rename the rom to .3DZ
