I bought a Wii memory card so I could play games on my friend's Wii and have my own game file...(see more)

the game I'm trying right now is Super Smash Brothers Brawl. She already has a file for that game on her Wii, so I can't just play it then transfer it onto my memory card (I want my own file, not a copy of hers). Is there anything I can do to have my own file?
