So when I tried to install a new .brasr file with WiiScrubber it said "Unable to find free space ". What do I do about this situation?

How can I change the in battle names? (Not the CSS, the name of the character that goes under the battle portrait in game) I can't seem to find any tuts on YouTube or Google on how to do it.

So I'm not sure if this is where I post this but there's a problem I'm having. When ever I change any of the characters portraits, the game crashes on the CSS. Did I do something wrong? (I'm on dolphin, i don't have a Wii)
