Wii U Modding Guide for 2021 Part 3 | Complete Guide

In the previous entries in this Wii U modding guide, we have covered how to fully softmod the Wii U to enable playing of Homebrew, dumping games and the modification of the Virtual Wii to allow homebrew. This week I will be going over how to backup and install Wii games and also show you how to play GameCube Games.

How to play backups on your vWii

There are two methods I would recommend allowing you to play Wii U backups on your Wii U. the first method would be installing USB Loader GX and running the games off an external disk drive or USB stick. This keeps your Wii game backups separate; however, you cannot use the same hard disk drive you store you Wii U games on as the disk will be formatted differently to work the vWii.

The second method is to inject the Wii game backup as Wii retail virtual console game. This method will let you install your game to your Wii U as an application and will load much like how Wii U backups created with Disc2app load.

How to load your Wii backups with USB loader GX on your Wii U

First, we are going to need to USB loader GX to your vWii. Luckily, we installed all the needed CIOS in part 2.  We will want to install the channel and forwarder so head over to the following addresses and grab the latest version of the application and forwarder (Make sure you choose vWii version for the forwarder!):


Extract the ‘apps’ folder from inside the latest version of USB loader GX to the root of your SD card.

Place the ‘.wad’ file to the ‘wad’ folder on the SD card. (If there is no folder there then create one)

To install the forwarder, we shall use ‘Yet Another Wad Manager’ which you can download from here.

Extract and copy the created folder to your ‘apps’ folder, then reinsert your SD card into your Wii U, boot up the console and start the vWii. Load up the Homebrew Channel and select ‘Yet Another Wad Manager’

Read the disclaimer and press ‘A’ a couple of times to continue. You will be asked to select the WAD location, Select ‘SD Card’ and press ‘A’. Use the D-pad to navigate down to the ‘WAD’ folder and press ‘A’, from here select our forwarder file and press ‘A’ once more to install the WAD.

Press the home button to return to the Homebrew Channel, then press it once more and return to the vWii’s system menu and you will find we have USB Loader GX set up as a channel. This means we do not have to boot up the Homebrew Channel every time we want to load a backup.


Now, as I mentioned earlier, we cannot use the same hard disk drive as we use for our Wii U games and homebrew. We need to use another form of storage, this can be another hard disk drive, a USB flash drive or even an SD card with a USB adapter.

Head over to http://www.wiibackupmanager.co.uk/downloads.html and download the latest version of Wii Backup Manager. Extract this to a folder on your PC (I put it in a folder called ‘wiibackup’ on my desktop, but you can put it wherever you want!).

Select which version is suitable for you and open the program, I have a 64-bit operating system so I chose the one ending in ‘WIN64’.

Once open navigate to tools and select format

Now, make sure you select the right drive to and make sure the file system is set to WBFS and click start. (As with all formatting, this will wipe all data saved on the drive so make sure there’s nothing important on there!)

This won’t take too long but will vary slightly depending on the size of your hard disk or thumb drive. (I’m using a small 8gb micro SD in a USB adapter for demonstration purposes). With the formatting complete we can insert the USB / Hard Disk into our Wii U and load up USB Loader GX.

*Your Wii U may prompt you to format the drive. Do not do this just cancel and load the vWii*

Once USB loader GX has launched, insert the game you want to backup. I will be using my copy of Resident Evil.

Insert the disc and you will be prompted to either mount the DVD drive or Install the game. Select install, USB Loader GX will confirm the game name and size, select install to continue and the game will be read from disc and copied to your storage media.

Wii U Part 3

Once completed the game will display as successfully installed. Installing the game this time took two attempts with my Wii U freezing at 77%, the Wii U can be a little fussy when it comes to what type of storage media you use, and the general consensus is that hard disk drives work a lot better!

with the game is installed you can use the Wii Mote to select the cover, select this and it will prompt you to download the cover art etc. Once downloaded you can start your game.

Now, personally, this is my least preferred method of backing up and installing Wii games. As you can see, it does work, however, I don’t like the fact you have to use a second hard disk drive or USB stick. I also don’t like the fact that you have to go into the vWii’s menu and then into another app to load up the games, but USB Loader GX does provide a nice way to organise your Wii game collection and backing up the Disc’s is relatively straight forward.

My preferred method of backing up your Wii games to play is a little easier in my opinion and it lets you use your ‘Normal’ Wii U Hard disk drive!

How to back up Wii games as apps on the Wii U menu

This method will let you run your Wii games directly from the Wii U menu and will install the game as an app you can easily launch.

For this, you will need a couple of things: – and an .ISO backup of your Wii game

TeconMoon’s WiiVC injector which you can download from here!

To make a .iso backup of your Wii game you can either follow the above steps using Wii backup manager to copy your ripped game from your hard drive to your PC as an ISO file. To do this connect the USB / HDD to your PC and launch Wii backup manager. From here click on Drive one and select the drive we formatted earlier to be WBFS, In my case, it was drive F:

I selected the file and clicked transfer, you will see this gives you the option for ISO, select that and the program will convert your WBFS stored image to ISO format. Alternatively, instead of selecting drive 1, you can insert your Wii game disc into a DVD drive and copy to ISO that way.

Once we have our ISO file made, extract and open TeconMoon’s WiiVC Injector.  You will be greeted with the following screen: –

As you can see there are quite a few options here to choose from but first, we need to enter some keys to allow the applications to be created. From here click on the last tab ‘Build Title’ you will need to fill in the two keys it asks for. I am afraid I cannot help you with the second key. For the first key just google ‘Wii U Common Key pastebin’ and you should find it quite easily, copy and paste it in. For the second key literally, google ‘that one title key site’ and you should be able to find it without too much hassle. Once they are both in, click save key on both.

Back in the main tab make sure Wii Retail Injection is selected, then click ‘game’ and locate your .ISO file. I will be using the Resident Evil game I backed up earlier. With that selected click ‘Download images from cucholix’s repo’, this will automatically pull and Icon and Banner to be used for your game. If you like you can select your own using the ‘Icon…’ button and the ‘Banner…’ button.

Head over to the GamePad/Meta Options tab, here you can change the name of the game and even set the gamepad to act as a classic controller. Lastly, head over to ‘Built Title’ tab and click build, select a location for your game (I chose Desktop) and the program will begin to build your game. This may take a while depending on the size of the game, but let it do its thing!


Once finished you will have your files in a folder starting with ‘WUP’ in the title. As you can probably guess we need to move this on to our Wii U’s SD card. Insert the SD card and copy to newly created into the ‘install’ folder. Then plug into your Wii U and load up the Homebrew Launcher.
