Smash Stack

Smash Stack is an exploit that uses a flaw in the custom stages of the game, Super Smash Bros. Brawl to load unauthorized code on the Wii. It only works on if you have the U.S. version or NTSC-U version of the game and works for all System Menu versions.

Smash Stack was created by Comex.

How it works

Smash Stack works by exploiting the way Super Smash Bros. Brawl loads stages. It is different from the Twilight Hack and Indiana Pwns exploits in the way it is loaded. Twilight Hack and Indiana Pwns exploit the save files of their respective games to execute a stack smash and load custom code. Super Smash Bros. Brawl's stage loader loads from the SD card and not from a save file on the Wii itself. Since the exploit is loaded from SD, it completely bypasses the System Menu, making it difficult for Nintendo to patch.

Requirements

Smash Stack currently only works on the NTSC-U version of the game, all other regions will not work. Use Indiana Pwns or another exploit depending on your System Menu version.

Using Smash Stack

Note: An SDHC card will not work with Super Smash Brothers Brawl. You must have an SD card that is 2GB or less.

1. Go to the stage builder, move any existing custom stages on Brawl to your SD card, and exit the stage builder. Smash Stack will not work if the console has any custom stages on it, even the three samples that come with a new file or the stages from the Smash Service. You will need to wait at least 24 hours for the stage from the Smash Service to be automatically deleted before trying to run this exploit. DO NOT go on Wi-Fi once the Smash Service stage is deleted.

2. Connect the SD card to your computer and rename the "private" folder to "privateold" in the root of the SD card.

3. Copy the "private" folder from the Smash Stack download to the root of the SD card.

4. Grab a *.elf file (HackMii Installer's boot.elf works) and put that in the root of the SD card.

5. Insert the SD card into the Wii.

6. Go back to the stage builder and the .elf file will load.
