Yea, I need to be able to backup my Brawl save so I can keep two separate files, one for my friend who uses my Wii and one for me because I like to do the singleplayer challenges and such on my own if necessary to better my skills, and if I can't copy my data to my SD card and my friend, say, beats SSE on difficult or something and unlocks a trophy on my file before I do, I'd be pissed. He did the same thing with Oblivion, got all the achievements I hadn't already gotten and beat everything in my own game before I did before I found that making him a separate gamertag on my Xbox HDD gave him his own set of files and whatnot. Can we please get more confirmation?
