Here is the link to the 100% save. You will put this on the SD card.
First, if you have the Minus PRIVATE folder on the root of the SD card, rename it to PRIVATEold.
Then, after extracting the folder you downloaded from the link I posted, copy it to the root of the SD card and rename it private.
Put your SD card into your Wii and check Data Management. Make sure the Brawl 100% save shows up on the SD card section. If it does, and it should, delete your old Brawl save on your Wii and copy the 100% save from your SD card to your Wii.
Once you do that, you can put the SD card back into your computer or whatever device you use, delete the private folder, and rename the PRIVATEold folder back to PRIVATE. Boot up Minus on your Wii, then try to connect to the servers. It should work properly.
Also, you can call me Darx, because that's what everyone calls me.
