Do you ever wonder if you can do more with a console than the company that created it allows you to? Well, you can! This is done through the use of somehing called "Homebrew." Homebrew is when you modify a console in some way that allows you to run external code on it, opening up infinite possabilities of what you can do with it. The easiest console to hack in my opinion is the Nintend Wii. And here's how you can!

But first, why would you want to hack a Wii? Some things you can do by hacking your Wii are:

Revive Wiilink24 (Online services)
Revive other services such as:
The Weather Channel, News Channel, Nintendo Channel, ect.
Run emulators for classic nintendo consoles, and other custom made apps!

Requirements:
An SD card formatted as FAT32
A Wii on System Menu version 4.3
A Windows/MacOS/Linux computer with an Internet connection!

STEP ONE:

Power on your console.
Go to Wii Settings.
Take note in the top right corner of the letter next to the system version. This letter corresponds to your system menu region, which you will need to know for the corresponding steps. Also, ensure that you are on System Menu version 4.3.

Navigate to Internet > Console Information. Take note of your FULL MAC address.

STEP TWO:
On your computer, open the browser and go to the HackMii website.
Input your Wii MAC address and region.
Ensure Bundle the HackMii Installer for me! is checked.
Cut either wire.

STEP THREE:
Insert your SD card into your computer.
Copy the private folder and the boot.elf file from the LetterBomb .zip to the root of your SD card.
Reinsert your SD card into your console.
The SD card must be inserted in the SD card slot located in the front of the Wii.
Using a USB to SD adapter plugged into the Wii’s USB port will not work.
On your Wii, return to the Wii Menu.
Launch the Wii Message Board.
Open the red letter with a bomb.
Ensure the date on your Wii is correct, otherwise you might be unable to find the letter.
In some cases, you may need to check the messages for tommorow or yesterday for the letter to show up.
If you don’t see the red letter, check if any errors appear in the SD card section of Data Management.
If any do, there may be an issue with the SD card format or the Wii’s SD card reader.
If your Wii freezes after clicking on the letter, you most likely chose the wrong system menu region for LetterBomb.
Go back to Step 2 and verify that you chose the right region.
If all is correct and there is freezing, keep on trying until it works.
If the exploit was successful, your device will have loaded the HackMii Installer.

PART TWO:
The Homebrew Channel is where you will go to launch homebrew applications. BootMii is a piece of software that can backup and restore your Wii’s NAND storage, and if installed in boot2, provide brick protection.
STEP ONE:
Your console should be powered on and showing the HackMii Installer from the previous part of the guide.
You will see a scam warning screen. Wait 30 seconds for the text “Press 1 to continue” to appear, then press 1.
Select Continue. Select Install the Homebrew Channel. Once it is completed, select Continue.
Select Back, then select BootMii.
Select Install BootMii as IOS. Once it is completed, select Continue.
If you have the option to Install BootMii as boot2, please do so as well.
Select Exit.
Your console will have booted into the Homebrew Channel.

STEP TWO:
You can now use the Homebrew Channel to launch homebrew apps, as well as BootMii for backing up and restoring your NAND if you were able to install it. Note: When installing homebrew applications on your SD Card or USB drive, your folder structure should look like this:

💾 SD Card or USB Drive | ╸📁 apps | ╸📁 AppName | ╸📄 boot.dol | ╸📄 meta.xml | ╸📄 icon.png

AppName2 are placeholder names. Do not nest multiple apps folders inside the apps folder itself..

PART THREE:
BootMii allows for backing up and restoring your Wii’s NAND storage. This page will guide you in backing up your Wii’s NAND to an SD Card, which you can then use however you like.

STEP ONE:
If you have BootMii installed as boot2, you will need to launch BootMii by restarting the console. Skip steps 1 and 2 if this is the case.
Power on your console.
Launch the Homebrew Channel.
Press the HOME Button, then select “Launch BootMii”.
Select the Options button (the icon with the gears).
Select the first button to the left. A NAND backup will start. You can watch the progress on the screen. “Bad Blocks” are normal, and mostly originate from the factory due to NAND binning.
Don’t worry when you see some on a NAND backup.
After the previous step completes, BootMii will verify the backup. Ideally, all the blocks should be green after the verification process.
If you have factory bad blocks with uncorrectable pages, these blocks may fail to verify.
As long all non-bad blocks are successfully verified, this should be fine.
Press the Back button (the one with an arrow), then press either the Wii Menu button or the Homebrew Channel button to exit BootMii.

STEP TWO:
Priiloader is an essential tool authored by DacoTaco that adds a level of brick protection to your Wii. It loads before the Wii System Menu does. The tool can also apply hacks that are used to enhance, unlock, and/or fix many System Menu features. Additionally, it can be used to quickly launch any Title or Homebrew, or change the way Wii autoboots.

Section I - Prep Work
Power off your console.
Insert your SD card or USB drive into your computer.
Copy the apps folder from the LoadPriiloader .zip to the root of your SD card or USB drive.
Copy the apps folder from the priiloader .zip to the root of your SD card or USB drive. (vWii only)
Copy the wiiu folder from the PriiloaderWiiUForwarder .zip to the root of your SD card.
Reinsert your SD card or USB drive into your console.

Section II - Installing Priiloader
Power on your console.
Launch the Homebrew Channel.
Launch Priiloader installer from the list of homebrew.
Press the + Button on Wii Remote or the A Button on a GameCube controller.
Press A to return to the Homebrew Channel.

Section III - Entering Priiloader
Press the HOME button, then select Exit to System Menu to exit the Homebrew Channel.
Your device will have loaded the Priiloader menu.
Later on, to enter it you can:
Hold the RESET on a Wii while turning it on Wii Only Hold the ESC key on a connected USB keyboard while turning on the console Wii, vWii and Mini Run the “Load Priiloader” tool from the HBC Wii, vWii and Mini Run the “Priiloader Wii U Forwarder” tool.

PART FOUR:
While cIOS has largely been supplanted by AHBPROT, which gives complete hardware access, it still has useful applications. For example, this enables the functionality of USB loaders like USB Loader GX and WiiFlow, alongside other pieces of homebrew like SaveGame Manager GX. You can skip this process if you want, but generally it extends your Wii with little to no downsides.

STEP ONE:
Power off your console.
Insert your SD card or USB drive into your computer.
On your computer, download NUS Downloader.
Copy all files from the NUS Downloader .zip to a folder on your computer.
Run NUS Downloader.exe.
Navigate to Database > IOS > IOS38, then select v4123.
Ensure that “Pack WAD” is checked. Don’t check “Patch IOS”. That is the cIOS Installer’s job.
Click Start NUS Download!.
Repeat the above steps for IOS56 v5661, IOS57 v5918 and IOS58 v6175.
When the process is complete, there will be a folder named titles in the same folder as the NUS Downloader.
Open the titles folder and navigate through them until you locate the four WAD files you downloaded.
Place each WAD file on the root of your SD card or USB drive.
This must be the same device containing the d2x cIOS Installer.

STEP TWO:
Copy the apps folder in the d2x-cios-installer .zip to the root of your SD card or USB drive.
Reinsert your SD card or USB drive into your console.
Power on your console. Launch the Homebrew Channel.
Launch d2x cIOS Installer from the list of homebrew.
When asked what IOS you would like to use, select IOS 58.
This should work in nearly all cases.
Now, you will install individual cIOS from 248-251.
The exact settings needed are listed below.
cIOS 248 Installation
Select cIOS <d2x-v11-beta1> Select cIOS base <38> Select cIOS slot <248> Select cIOS revision <65535>
cIOS 249 Installation
Select cIOS <d2x-v11-beta1> Select cIOS base <56> Select cIOS slot <249> Select cIOS revision <65535>
cIOS 250 Installation
Select cIOS <d2x-v11-beta1> Select cIOS base <57> Select cIOS slot <250> Select cIOS revision <65535>
cIOS 251 Installation
Select cIOS <d2x-v11-beta1> Select cIOS base <58> Select cIOS slot <251> Select cIOS revision <65535>

PART FIVE:
The Open Shop Channel is a homebrew app repository created by dhtdht020, and is currently the preferred way to download homebrew. Not only is it more convenient due to having the most commonly used homebrew in one place, but it is also safer as apps are manually added to the repository. You can see where an app is being obtained from by checking its manifest. There are two methods to use the Open Shop Channel: on your Wii through the Homebrew Browser, or outside of your Wii through OSCDL.

STEP ONE:
Method I - Homebrew Browser
Download the reccomended .zip file from the Open Shop Channel website.
Extract the apps folder in the archive to the root of your SD card or USB drive.
Optionally, the archive also comes with a guide on how to use the Homebrew Browser.
Insert your SD card or USB drive into your Wii, and go to the Homebrew Channel.
The Homebrew Browser should now display.

Method II - OSCDL
Download oscdl-installer.exe and run the installer.
Optionally, you may instead download oscdl-standalone.exe, which does not have to be installed and instead runs as a portable executable.
If you get a User Account Control pop-up that asks whether or not you would like the program to make changes to your PC, select Yes.
Open Shop Channel is a safe application.
Let the installer run, and then launch OSCDL once the process is finished.
Find an application that you would like to get, and press the Download button.
Alternatively, you can send the app directly to your Wii (this requires that your computer and Wii be on the same network).
A .zip file containing your app should download to wherever you specified the directory to be.
Extract the apps folder in this archive to the root of your SD card or USB drive.
Insert your SD card or USB drive into your Wii, and go to the Homebrew Channel.
Your downloaded piece of homebrew should now display.
