Yeah.
Basically, youneed an SD Card. 2GB, prefered.
Go to your Wii, Brawl, delete all custom stages.
Put the contents of the Folder on your SD Card.
Then go to Custom Stages.
The Screen will glitch out, then go to the SD Card and it's contents, which is also where the hack is.
That's the project m way and i did that and nothing happened
