This seem's of a rather simple "trial and error" to me.Ok try this just delete your brawl + folder's. Side note not the app folder at the root of the sd card because if you deleted your brawl + app it wont show in homebrew channel. Then plug it into the wii and click brawl + in the homebrew channel and press update and if that doesnt work then try deleteing brawl + completely because from personal exp i cant load my hacks + its hacks. It will ask do you want to replace this file and if i say no then it wont update lol and there's a whole new ver of it.
Its's called brawl - idk why they called it that and i know nothing about it really.
!!! I hope this helps!!!
