Quick disclaimer: This post is about evWii, a homebrew plugin that vastly improves vWii and GameCube game visual quality compared to stock settings. Reaching out here in good faith—hope this stays within post guidelines!

Hey everyone!

If you’ve been messing around with the evWii plugin on Aroma, you probably know the exact pain I just went through. Nintendo’s default vWii scaling leaves annoying overscan/borders, and finding actual solid display numbers for the config file online feels impossible.

After falling down a massive rabbit hole of testing and fine-tuning the DMCU viewport parameters, I finally dialed in values that give you a clean picture without clipping or leaving an ugly blurry picture.

If you’re ready to finally end the suffering and fix your config file once and for all, paste these numbers in:

My personal values

​Now, if you don't want those black bars on the left and right sides of the screen these are the settings for you! (these are the values that I used before and posted 4 months ago):

Pure 16:9 Values (Also great for Gamecube games)

Didn't take a photo of these values on my TV, but trust me, it's the exact same as the first config—just without the side black bars so it's pure 16:9.

Here's my old post if you're interested: https://www.reddit.com/r/WiiUHacks/s/15bSzZsnFU

The best values for GameCube?:

GameCube testing status:

Value 1: Didn't test, didn't have time.

Value 2: Tested, verified, looks amazing.

TL;DR: Stop guessing numbers, paste MY config, and go play your games. You're welcome!

If this helped you, great! If your screen still looks weird... well, at least we suffered together. Enjoy!

If your virtual Wii (vWii) is corrupted, bricks on launch, or fails to boot and you don't have a nand backup, you can completely restore it to factory settings without needing a prior NAND backup.

I'm making this guide because I see how different people try to restore their vWii and face different errors when trying to restore it by using different tools.

This method uses vWii Decaffeinator to wipe the corrupted vWii NAND and forces the official Wii U system update to download and reinstall a clean vWii system.

────────────────────────────

⚠️ IMPORTANT PREREQUISITES & WARNINGS

• Remove all Wii Discs & USB Devices: Eject any game disc and unplug all external hard drives/flash drives before starting. Leave only your SD card inserted.

• System Version: Your Wii U must already be on the latest firmware (5.5.5 or 5.5.6, depending on the region) and running the Aroma custom firmware.

• Theme Warning: Ensure you are using the default, stock Wii U menu theme. If you have custom themes installed (via Utheme, etc.), remove them first to avoid a console freeze.

• Internet Connection: A stable Wi-Fi connection is required on your Wii U to download the fresh vWii files.

────────────────────────────

STEP 1: Prepare the SD Card & vWii Decaffeinator

1. Download the latest .wuhb version of vWii Decaffeinator (do not use the old .rpx version).

2. Connect your SD card to your PC.

3. Move the decaffeinator.wuhb file inside the sd:/wiiu/apps/ folder.

4. Safely eject the SD card and put it back into your Wii U.

────────────────────────────

STEP 2: Unblock System Updates

1. Turn on your Wii U while holding the ⊕ button on your GamePad/Controller to access the Environment Loader menu.

2. Look at the bottom of the screen. If it says Updates Blocked, press ⊕ and ⊖ together until it changes to Updates Not Blocked.

3. Highlight Wii U Menu, press Ⓨ to set it as default Autoboot (the text will turn yellow), then press Ⓐ to boot into the menu.

4. (Optional) If a prompt appears warning you that an update folder exists, skip or dismiss it.

────────────────────────────

STEP 3: Configure FTPiiU & Run Decaffeinator

1. Crucial Fix: If Decaffeinator gives you a "Failed to mount..." error, return to the Wii U Menu. Open the Aroma WUT Connect menu via the button combo (L + Down D-Pad + Minus). Go to ftpiiu → set Allow access to system files to FALSE.

2. Launch vWii Decaffeinator from your Wii U Menu.

3. If you suspect your vWii brick was caused recently by installing a corrupted channel (WAD file) or a bad channel banner, you don't necessarily have to wipe everything. In vWii Decaffeinator, you can select Light Mode instead of Aggressive Mode. It will only delete and rebuild the core vWii system files, but it will preserve your save files and installed homebrew channels. If Light Mode doesn't fix the issue, you can always go back and run the process again. Select Aggressive Mode. This will safely wipe your corrupted vWii NAND. Confirm and bypass the warning by pressing ⊕.

4. Once finished, the app will automatically redirect you to System Settings. Do not update yet! Exit the System Settings and return to the Wii U Menu

────────────────────────────

STEP 4: Disable Aroma Autoboot Temporarily

1. Open the Payload-Loader Installer app from your Wii U Menu.

2. Select Check → Boot Options.

3. Select Switch back to Wii U Menu.

4. Pay attention: near this option it says that this option could make the Wii U unusable if there's anything modified (for example a custom theme installed) but this option is safe. After that, press Ⓐ to shut down the console.

────────────────────────────

STEP 5: Reinstall the vWii NAND via System Update

1. Turn on your console normally (it will boot into standard stock firmware without Aroma).

2. Go to System Settings → System Update.

3. Start the update. The console will realize the vWii partition is missing and will safely download and install a fresh, clean vWii NAND. This process takes about 10–20 minutes.

4. Once completed, reboot and test your vWii channel to ensure it functions perfectly.

────────────────────────────

STEP 6: Re-enable Aroma Autoboot

After you have verified the vWii perfectly works, it is now time to turn back to the Autoboot.

1. Launch the Health and Safety app (or your entry point, so in the normal Wii U Menu) to trigger Aroma.

2. Once it loads, open Payload-Loader Installer again.

3. Go to Check → Boot Options → Switch to Payload-Loader.

4. Press Ⓐ to shut down.

5. Turn on the console, hold ⊕, and use the ⊕ and ⊖ combo to Block Updates again so your console stays safe.

Your original vWii is now fully restored and clean! Don't forget to make a NAND backup with nanddumper now that it is working properly, so you won't have to do all this process again.

Hope this guide helps the people who are trying to get their vWii back.

I have been considering buying a modded Wii U instead of a modded Wii because I heard it can run essentially all Wii games upscaled to 1080p, but I still have a few doubts about it.

- How well do Wii games run on Wii U? Are there issues with the upscaling? If so, can those issues be addressed in some way? And if not, are those scaling issues that bad in the first place or do they only affect nitpicky people?

- Can I use Wii homebrew apps on Wii U via the Wii menu mode? For example, I want to play CTGP-R and connect to private servers to play Wii games online. Is this possible on Wii U?

I bought a never modded Wii U recently. I wanted to mod it and of course i need a hard drive or sd card. Currently i can only use a 16 gb micro sd card on my home.

My first idea was to buy a 256 gb normal micro sd card and use SDUSB with it, but i heard that they broke within months and that you need a high endurance card which they are expensive. My current idea was to use that 16 gb micro sd card for only the homebrew and buy a large external hard drive just for the wiiu/vwii/gamecube games.

Which idea or alternative idea is the best? Are the wii u games playable from a external hard drive? Because they are not in full speed compare to a sd card and i am thinking of some rendering popups could happen in gameplay but dont know if thats true.

I want my PS5 or any controller that i have, act as a Wii Classic / Wii Pro Controller, but using bloopair and entering vWii mode doesnt work, but i saw that the 8bitdo for the SNES/SFC/NES Classic have the same connector as the extension port on the Wiimotes.

(Kiosk Project - Wii U去, Wii UE, Wii Ue, Wiiosk U)

OVERVIEW:
People often see this, and ask… “What am I looking at? What is this? What is the point?”

The Wii UE was an attempt to create a type of ‘in-house’ Wii U oriented NAS server of sorts. However, these capabilities never came to fruition. HOWEVER, included in this kiosk was wireless HDMI, and with 4 consoles on wheels, the ability to remotely stream to 4 television displays from one unit became possible.
(Think of this kiosk like a very complex wireless internet router but for video signals)

Ultimately, the prototype ‘known as Wii UE’ or ‘Wii U去’ (meaning Wii U’Go’ in Japan)… was a failed prototype that served as a learning experience.

Early 2026, the ‘Wii UE’ was reimagined into the “Wii Ue” (lowercase e naming) and reinvented the kiosk concept by putting the gamepad onto a tripod (known internally as DRC receivers).
+ this truly made the kiosk experience portable and ‘on the goal’ while feeling genuine.

Though this summer, I still craved for a true stationary kiosk experience so I branched off the project into what has become the Wiiosk U. Both the Wii Ue and Wiiosk U co-exist as of currently.
From here the project will be taken into two directions.

要するに、任天堂さん、私を訴えないでください。訴訟を起こしても何の得にもなりませんし、私はただ個人的な情熱を注いだプロジェクトとして、ささやかな冒険を楽しんでいるだけなのですから。

Would like to see what it's capable of, won't happen though if there isn't some kind of unofficial patch for it. If there is a way to make it work again let me know👍👍
