[slickric33]

Smash Stack
For US Wii owners on 4.3.
WARNING: SPOILER INSIDE

First off, this will not work if you have ANY custom stages, including the 3 that come with a new save file.
Delete/move them, and then launch Super Smash Bros. Brawl.
Once on the Main Menu select Vault, then select Stage Builder.
The Smash Stack exploit should take over and you should see the Hackmii Installer running.

the wii just starts making a high pitched noise and nothing happens at this for 2 hours and cant figure out whats wrong???????

Did you delete the custom stages before you attempted Smash Stack?
