Introduction

Step 50: It should install the files and the UI elements. Step 51: After all is said and done, you should have an app that says “Smash Bros. Wii U Mod Enabler”. If you have an external hard drive: you can then restart the console, plug in your hard drive and go to System Settings to move the app back onto your hard drive.
Open the Wii system messages and browse to yesterday’s messages. The LetterBomb icon should show up. Click it with the Wii remote pointer. The Wii will install LetterBomb and Hackmii.

If you thought Paradox’s grand strategy game Stellaris sounded very Star Trekky with its big alien alliances and deep space exploration, you are not alone. Stellaris is a space opera, played out in three acts. Go into the Wii system mail (The little envelope icon in the bottom right corner), Look for a red Letter with a bomb in it, and click it (You may have to go forward or backwards a few days). The Icon will be identical to the one on the Letter Bomb website!

I picked up a Wii earlier this year and decided to hack it to see what benefits that would provide. The results were, to be honest, quite spectacular. After spending quite some time digging through various HOWTOs scattered across the internet with often conflicting or out of date information, testing different configurations and applications, and running through quite a bit of trial-and-error, I finally have a solid and extremely functional Wii that lets me do pretty much anything I want with it. Some of the highlights include:

Boot directly to WiiFlow (a slick homebrew launcher application), bypassing the health and safety screen and main Wii menu
Rip any Wii or GameCube game to an attached 500 GB USB drive
Browse, select, and launch any previously ripped Wii game from the USB drive
Browse, select, and launch any previously ripped GameCube game from the USB drive (note: this requires a GameCube-compatible Wii)
Play older games via emulators (though, honestly, PC emulators provide a better experience)
Run various and miscellaneous utilities such Wii and GameCube memory card management utilities, allowing me to copy/backup saved games from the Wii or GameCube memory card to my computer

The end result is that I have every one of my 27 Wii games and and 25 GameCube games ripped and stored on the USB drive, and I can play any one of them now by simply powering on the Wii, browsing to the desired game in WiiFlow, and pressing A on the controller. No more disc swapping, and no more worrying about where to even store all of the games so they're accessible (they're now all boxed up in a closet, along with my GameCube). It's a wonderful thing. :-)

Of course, none of this would be possible without all of the hard work by the various hackers, modders, developers, and other enthusiasts that have worked on this over the years, so I fully acknowledge all of their efforts. However, because all of this developed over time, as I mentioned above most of the information out there related to Wii hacking is either dated, incomplete, or conflicting with each other. As my small way of giving back and giving thanks, I put together my own HOWTO covering the most important details regarding exploiting the Wii, setting up your hardware, then installing and configuring WiiFlow for maximal enjoyment.

Please note: I would consider the Homebrew Setup page on the WiiBrew wiki to be the most authoritative source of information about Wii hacking. This guide supplements the existing documentation to include additional details that I consider important, and focuses on the Smash Stack method since that works all versions of Wii as well as all versions the virtual Wii included on Wii U (as of 4.0.3).

It is important to note, however, that other exploits are available. If you do not have (or have access to) a copy of Super Smash Bros. Brawl, please review the Homebrew Setup page for alternative options. In particular, I've also successfully hacked a Wii using the LetterBomb exploit, which can be done on any (real) Wii running System Menu 4.3.

A Brief Note on Ethics and Legality

I'd like to make one thing clear right up front: this tutorial is intended to allow you to (much) more easily and conveniently enjoy playing your own games. It is not meant to encourage piracy of any sort. Please do not use this as an excuse to simply download and play Wii games without paying for them; it is ethically, morally, and legally wrong to do so. Please rip and play only your own legally obtained games, and if you decide to later give away or sell one of the games that you ripped, you must delete your ripped copy as well.

Part I - Exploit

Before custom/homebrew software can be run on the Wii, it must first be hacked. This is accomplished by exploiting some weakness in either a game or in the Wii System Menu. The exploit is essentially used as a way to break out of the Wii's normally protected environment and install the Homebrew Channel which, once installed, can itself be used to run additional homebrew applications without the need for further exploits.

Prerequisites

The following components are necessary to exploit the Wii. The versions in parentheses were the latest version available at the time of this writing; any newer version should also generally work.

Super Smash Bros. Brawl - this exploit requires SSBB; as noted above, if you do not have SSBB, please see the Homebrew Setup page for alternative exploit options and directions
Smash Stack - exploits SSBB and allows the HackMii Installer to be launched; please also read the information on the linked page so you understand how it's supposed to work
HackMii Installer (1.2) - installs Homebrew Channel (used to launch other, additional homebrew applications) and BootMii

SD Card Preparation

Find a compatible SD card. This is the trickiest part of the process, as only certain SD cards will work. For Smash Stack, it must be SD (not SDHC, not microSD, etc.), and must be 2 GB or less. Even then, compatibility is not guaranteed. See the linked compatibility list for more information.
Format the SD card with a FAT32 filesystem. It's possible to do this directly from Linux with mkfs.vfat, but for maximum compatibility (and to remove as many variables as possible) SD Formatter 4.0 is recommended if you have access to a Windows box.
Copy the private/ directory from Smash Stack to the root of your SD card. If a private/ directory already exists (ie., you re-used an SD card without formatting it), rename the existing directory.
Copy boot.elf from HackMii Installer to the root of your SD card. Nothing else is required from HackMii Installer.

Wii Preparation

Note: Do not insert the SD card at this time.

Launch SSBB
Create a new save file, if prompted
Open Vault, then Stage Builder
Delete all three of the pre-created sample stages (plus any other stages you may have previously created)
Exit back to the Smash Brothers, then exit the game

Homebrew Channel Installation

Insert the prepared SD card
Launch SSBB
Open Vault, then Stage Builder
The exploit should launch immediately, displaying a black screen with white text followed by a prompt about HackMii. If instead
1. the stage builder opens, you didn't setup the SD card properly. Review the SD Card Preparation instructions and try again.
2. the game freezes, your SD card may not be compatible. Try repeating the SD Card Preparation steps, including performing a FULL (overwrite) format of your SD card using SD Formatter, and try again. If it still fails, you'll probably need another SD card.
Press 1 to continue, then A to continue again
Select Install The Homebrew Channel, and choose to continue
If you have the option (it's not supported on all Wii models), I also recommend installing BootMii. This can be used to backup and (potentially) restore your NAND memory in case of a failure.
When finished, select Exit
You should be taken to the Homebrew Channel, which will be empty by default. Continuing to the WiiFlow section for detailed information regarding setting up WiiFlow to launch Wii and GameCube games from USB media.
