How to install Haxchi (Or CBHC)

Why? I thought it would be fun to make a guide like this! :D

IMPORANT: With the closure of the eShop for Wii U and 3DS, It is no longer possible to purchase any new DS VC game. Therefore the only way to install Haxchi is if you already have had a compatible DS game from before.

What's required:

A legally purchased DS Virtual Console game compatible with Haxchi (most common is Brain Age)
An SD Card (Recomended 32 GB)
A device such as a computer that can transfer files to the SD card.
A Wii U with internet access (With no homebrew present, isfshax is okay but make sure wafel_payloader.ipx has been removed)

SD Prep:

This section will place all the required files needed to get started, as well as some additional homebrew apps.

What you need:

The Haxchi/CBHC Complete All in One zip file.

Be sure to have your SD card formatted as FAT32, not exFAT or NTFS. You can use GUIFormat with 32K (32768) allocation unit size to format it.

A quick note about SD Cards: you cannot use a USB adapter and plug it into the back of the console, it wont work. You need to use the front SD card slot on the console.

Instructions:

Insert your SD card into your computer.
Copy the 4 folders from the Haxchi Complete All in One.zip (the "haxchi", "cbhc", "install", and "wiiu" folders) to the root of your SD card.

Wait, that's it?

Yes, that zip file included all the apps and files needed to homebrew, but we are not finished homebrewing yet.

Here is what we just copied over:

Homebrew Launcher Installer
- Launches the Homebrew Launcher through an online exploit
The Homebrew Launcher
- Launches various homebrew apps
The Homebrew Launcher Channel
- Lets you launch the Homebrew Launcher from the Wii U Home Menu
WUP Installer GX2
- Installs WUP formatted applications (For example, the Homebrew Launcher Channel)
Wii U NAND Dumper
- Backs up your Wii U's internal storage incase of a disaster
SaveMii
- A save manager for your Wii U
The Homebrew App Store
- Where you can get new homebrew apps
Haxchi Installer
- Installs Haxchi
CBHC Installer
- Installs CBHC

Thats alot of stuff right? Don't worry, they will be very useful.

Browser Exploit

Congrats on making it this far! I fully believe you can make it all the way!

Now, to install cfw on the system, we need to launch the Homebrew Launcher through a browser exploit. Be sure you have internet access on your Wii U.

Instructions:

Eject, and remove your SD card from your computer and insert it into your Wii U.
Launch the internet browser and navigate to wiiuexploit.xyz website.
Click on Run Exploit! to launch the exploit. Your console should launch the homebrew launcher.

The browser should go to a blank web page after clicking Run Exploit! After a few seconds it should fade to a white screen, then fade to a screen with the WIi U logo at the bottom right, with the loading sound playing.
If your Wii U gets stuck on a white or otherwise frozen screen, wait a few seconds. If nothing happens, reboot the console, reset the browser's save data and try again.

Important: Do not search for the website, the search engine does not work. Instead, type the URL in the bar at the top of the gamepad.

Making A NAND Backup

Now we need to create a NAND backup that can be restored incase anything goes wrong.

Instructions:

Making an MLC dump is optional, the MLC contains game and save data and is not needed to recover most types of bricks. If you do decide to dump your MLC, make sure you have an SD card that is larger than 8 or 32 GB depending on your console.

Navigate through the Homebrew Launcher and launch the Wii U NAND Dumper app.
Use the Wii U GamePad’s D-Pad to enter the following configuration:
- Dump SLC: yes
- Dump SLCCMPT: yes
- Dump MLC: optional
- Dump OTP: yes
- Dump SEEPROM: yes
Press the A button to start the dumping process.
When the process completed, power off your Wii U, take your SD Card out of the Wii U and plug it into your PC.
To make sure you don’t lose the files, copy the slc.bin, slccmpt.bin, seeprom.bin, otp.bin and if you chose to go with a full backup, every mlc.bin.part file to your computer.
- They will appear on the root of your SD card
Delete the files from your SD card to free up space.

Nice! You just backed up your NAND incase something goes wrong, like a brick for example.

Installing Haxchi:

With all that done, we can finally install Haxchi onto our console!

First, we will download the DS game, then use the Haxchi Installer to install it.

Console Prep:

Unplug all USB devices from the back of the console (The Host DS VC game is not allowed to be on a USB drive)
Power on your Wii U and ensure you are logged into your NNID with the DS VC game
Navigate to the Nintendo eShop and redownload your chosen game here is a list

Once the download is complete you may as well test it to make sure it works. (always a good idea, not necessary)
