If you play Brawl, you can backup all of your stages onto an SD Card, then move all of its contents onto your computer for safe keeping until after we’re done.This includes the default custom stages and downloaded stages, so if you don’t play Brawl normally, you will still need to either delete or move those stages.

Update Your Wii Firmware The first thing you’ll want to do is make sure you update your Wii to the latest version, which as of this writing is version 4.3, through the System Menu.

Do it now, so you don’t have any issues with the rest of the process.

Prepare Smash Bros In order for the Smash Stack exploit to work, you need to make sure you don’t have any custom stages in Super Smash Bros Brawl saved.

And yes, in case you are wondering, this does work with the latest version 4.3 firmware update.

Here’s how to use the Smash Stack exploit to hack your Wii with the latest system menu and enable all of that and more!

Before we get started, it’s important to mention that this guide will modify the software on your Wii, which will void the warranty, and there’s a chance that you could make your Wii console unusable if things go wrong.

We didn’t have any problems hacking our own Wiis, but your mileage may vary.

Be sure to read the entire process carefully before starting.

The Smash Stack exploit requires – you guessed it – Super Smash Bros Brawl in order to execute it, as well as one Game Cube controller, and you can borrow both from a friend or find them cheap online.

You’ll also need an SD/SDHC card for all of the homebrew (“home brewed” apps) you want download—I’d recommend at least a 1 GB card to make sure you have enough space.

It’s also a good idea to check out the Wiibrew Compatibility Page for your SD card, in case you want to ensure maximum compatibility.
