So I go on the wii menu on my wii u and put in my SD card, wait for about half a minute and then put my brawl disc in. I go to stage builder and it brings me to project M and it works fine from there. But if I go into a match with new charcters/ alts it freezes. Even if I don't do that, after one round of pm it goes back to brawl but all the characters are still there. Confirming it not working. Because if I go to an alt that is not in brawl it freezes. Yesterday it worked perfectly but I turned off my wii u and I've been trying to fix this ever since. Can someone please help me? Again. I'm using this on wii u with a 2gb Toshiba SD card.
