Moonlight Wii U is a port of Moonlight Embedded, which is an open source client for Sunshine and NVIDIA GameStream. Moonlight allows you to stream your full collection of games and applications from your PC to other devices to play them remotely.

It's using the hardware-accelerated h264 library of the Wii U which results in pretty fast decoding.
Using my LAN Adapter 720p@60fps runs almost flawlessly.

Here's a little demo (and april fools) video:

Quick Start​

A Wii U LAN Adapter is recommended!

• Grab the latest version from the releases page and extract it to the root of your SD Card.
• Enter the IP of your Sunshine/GFE server in the moonlight.conf file located at sd:/wiiu/apps/moonlight.
• Ensure your Sunshine/GFE server and Wii U are on the same network.
• If using GFE, turn on Shield Streaming in the GFE settings.
• Pair Moonlight Wii U with the server.
• Accept the pairing confirmation on your PC.
• Connect to the server with Moonlight Wii U.
• Play games!

Configuration
You can configure all of the documented settings in the moonlight.conf file located at sd:/wiiu/apps/moonlight.
Note that a lot of option are commented out by default, to edit them you need to remove the # in front of them.

Supported controllers

• Gamepad (can be disabled with the disable_gamepad option).
• Up to 4 Wii U Pro Controllers and Wii Classic Controllers (Pro).
  The Gamepad needs to be disabled to use the 4th controller.

Troubleshooting​

Input doesn't work when using Sunshine​

Verify that you've installed Nefarius Virtual Gamepad and restarted your PC after the installation.

The stream disconnects frequently/immediately​

Depending on your network connection you need to adjust the configuration to find a stable bitrate and resolution.Try something like this to get started:

width = 854
height = 480
fps = 30

bitrate = 1500

Then slowly increase the bitrate until the stream is no longer stable.

Can't find app Steam​

Moonlight Wii U tries to start the app "Steam" by default, but sunshine does not have a default Application called "Steam".
You can either rename the app in the moonlight.conf to

app = Steam Big Picture

which is a default option in sunshine or add a new application called "Steam" in the sunshine configuration.

WTF you going on about? I've been a PC tech probably longer than you've been alive.
I got my PC IP from me typing it in as I have it set manually for the last 15 years.
I use AdGuard which is an app for Windows, Android, IOS, and Chrome addon. Its an ad blocker, firewall, etc. I've disabled it as it also blocks ports and crap like that. I'll enable it as soon as I can pair/sync the WiiU to the PC.

OMG, I wasn't intend to offend you , I just would like to help you.....in this case did you unlock your Windows the related online functions and check them in Turn Windows future On and Off?

Stop. I guess your a kid and guessing. You obviously dont have any idea what your talking about.
Years ago I went through all this with the nvidia support and they were about as good as you. no idea what they are going on about.
They also said the obvious. Start, stop, reboot, reinstall, blah blah blah. All the typical things you do BEFORE asking for help.
I've been trying for about 5 hours before I commented.

@NakedFaerie really I would like to help you, I have done my personal Server inside the house and to settle the personal line sometimes could be an hell....I know what I'm talking about. Otherwise how can I let it work; sometimes it doesn't matter how long and nice you could be nice with the PC, the PC and informatics are always to learn never will be done, it's also for me . No body it has the true on them hands. Ok, in this case I stop my self .

• Accept the pairing confirmation on your PC

This is the problem I have. There is no pairing confirmation popup for me.
This is a major GFE bug. Anyone else had it or knows how to fix it?

Maybe try using sunshine or open-stream if GFE doesn't work.
Also no need to start an argument here.

Sunshine gives an error "Error: Failed to create D3D11 device [0x80070057]"
Open-stream, thats screen sharing not for moonlight game streaming I think.

@NakedFaerie if you think they not helping just igrone them.

but @CrisMod is a person who understands more than 99.9% of people how the Wii U works. if you dont want help from him, you will most likley look in the void in the Wii U Scene.

 

[KyleTheUltimate]

Is there a way to invert A and B as well as X and Y within Moonlight for Wii U? I keep trying to change the controls in Steam's Big Picture mode, but games keep reading the Gamepad as an Xbox controller but with a Nintendo layout, as in, Xbox's B is Nintendo's B when it should be A. So games don't control properly.

If you read my problem you will see its NOT a WiiU problem its a PC problem so irrelevant.
I got moonlight on iPad, Android Phone, WiiU, Vita and ALL cant pair. The pairing dialog box never pops up so its not platform related, its PC GFE related.

 

[tooknie]

f you read my problem you will see its NOT a WiiU problem its a PC problem so irrelevant.

Regardless as to whether your problem is PC or WiiU based, you were incredibly rude to someone who was trying to help you.

Check your attitude, dude.

OMG !!!
A while ago I created a post asking if it would be possible to use any streaming app on Wii U, be it Playstation Remote Play, Playstation Now, Steam Link, Geforce Now, xCloud, anything, but I was told that Wii U was slow too much for something like that.

I can't believe this happened, I can't believe this is really possible, the modders here are just amazing.

I can't wait to test this out.

Basically yeah, Gary has said he's open to the idea of a Playstation Remote Play port but hasn't got a PS4

In all honesty I'd probably get more use out of a Remote Play port.

I would love to see the PS Remote Play on the Wii U, yeah... I have a Smartphone (but to be honest, I almost never use it for remote play, I use it more on my PC to be able to play in the bedroom since the PS4 is on the TV in the living room), but being able to play PS4 or PS5 games on the Wii U GamePad seems insane, especially if I can keep up a good speed.

Is this with touch-support? It's something that was anticipated for so many years

I was looking for that thread because I knew you would immediately be excited for it https://gbatemp.net/threads/wiiutablet-use-the-gamepad-as-pc-drawing-tablet.388012/page-2 like I said before it's a hell of a long time coming

 

[CrisMod]

@Moon164 mate I think not loong time ago we were talking about to Stream on Wii U that was a pain, for the lack of the hardware tecnology...
Especially me that I'm a person obsessed about the INPUT LAG, for me half second and more of input lag it's really unplayable, especially if you play with fighters games or online games......

I told approximately this:
---------------------------------------------------------------------------------------------------------------------------------------------------------------------
One period my cousin ask the same thing, and I tried to go more deep about, and after a lot of sourcing I arrived to these conclusions
To have this implementation for Wii U the developer need to implement this futures for the console and optimise it, as much as he can to work perfectly. So, from my testing, the developer will face these problems (with all the implementation of final user, to minimize the bottlenecks and use at least the Cat 7 Ethernet Quality):

• The streaming from the PS4 to Wii U it will work in this way: PS4 --- > Ethernet High Quality Router --- > Base Wii U Console --- > 5GHZ N (Class) Wifi Wii U PAD
• The streaming from PS4 to Android Phone: PS4 --- > Ethernet High Quality Router --- > WiFi AC 5GHZ Discrete Android Phone
• The streaming from PS4 to PSVita: PS4 --- > 2.4 GHz WIFI Direct to PSVita (it needs the Router, but It will use it at the beginning, just for the settings because the PSVita it's WiFi N 2.4 GHz biderectional antenna and can connect in WiFi Direct to the console). The 2.4 GHz Wifi and the N, it's not the best for streaming in real time because the 5 GHz it's fastest but shortes as range, but here we have the WiFi Direct that helps it.

So as you can noticed, the Wii U will have more hardwares in between to stream the video image, and what happens, you should know the Input Lag right?! So, the input lag exist from the Console to the TV example (imperceptible) the Projector or some old IPS Monitor (even if less percettable in front of Projector side) suffer so much about Input Lag; the Input Lag it's the moment when you press one button and react to the imagine. So, if you need to play example with Final Fantasy or some other game like The Last of US, that almost of the time it's not requires so fast rections from the situations displaied on the screen; more and less you are fine. But the problems comes if you need to play with some fast FPS game or fighter like Tekken 7 or Mortal Kombat 11. So, when you connect the PS4 (Pro has better specs under WIFi as well) to the Android phone and a nice high costing router ander AC Wifi you will have close or over of 1 second the input lag, I tested in front of my professionl Monitor to stream the same image to my Android Phone Huawei Mate Pro 20. And even from Menu you can experienced of this annoyng input lag.
Now, to have the best resaults, I have isolated the Router and created the special Door where my Phone the Router and PS4 can catch the maximum performance as they can; so the resaults are still not really sutisfied about. Yes, at the beginning you can say it's cool, but when you play more it's a bit pain this in-put lag. Because, what the hardware are processing it's not in real time of what the streaming it's showing.

So, PSVita with the worst hardware specs can processing better in front of the other better specs hardwares because it's Wifi Direct to the Console (similar to Wii U console and Wii U PAD); but the Wii U under this point it's better because it has better specs WIFI communication with the base, and it doesn’t need to processing the packaging that the base console will send to the PAD (because the Wii U PAD it's totally SLAVE hardware that display what the console processing). PSVita can take advantage from WiFi Direct, but it's not really perfect, because it's still needs to processing the packages sent from the console. And another minus of this situation is, for absurd the games displayed. Which means the Playstation games are set to be displayed to the big screen, with space and certain of numbers of pixel, translated have means that the games in PSVIta or in Wii U, the DPI of the screen, to consult the Menu or words in the games will be soooooo small and not readable because an imagine from 1080p or big inch TV it's displayed and shrink into to 5 to 6 inch monitor. So the optimizations to watch the games in such small monitors you will fill dizzy (I can tell you because we already tested. The games of Wii U are already settled to be displayed into the small screen and the Wii or Game Cube can be displayed well because they are small resolution that it's needs to be fit into an Higher resolution 480P screen or the PAD. So, will not be a Higher resolution shrink into a less resolution and smaller display (as PS4/PSVita it makes).
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
For me to see the GeForce Experience that can send all the data infos to the Wii U in real time, it's really impressed job I'm really excited about this and what Gary port, and I believe Nvidia makes really great job to make such processing of data streaming in Real Time (by network with the router in between), where Moonlight can replicate with such perform on Wii U .
This will open a lot of scenario, because your PAD can control the PC and play with a lot of Arcade porting....and it's really amazing this.
These past month I was looking somenting to connect the PAD directly to the PC, but as I found in other projects it's really difficult to implement such thing to break the 5Ghz Wifi from the PAD.
So, if can be implemented the stremaing in Real Time (and not like the PS4 solution to Android Phones because of the input lag) like PS4/5 to PSVita as Nvidia makes with Geforce Experience to Nvidia Shield (or the open project Moonlight), this will be the APOTHEOSIS of modding for Wii U!!!!

Eh I don't have a gamer PC so nice but no candy for me, thanks.

 

[Deleted member 42501]

Impressive.

The Wii U really could've been the best console ever had it stuck around for a second revision ala DS>DSL as the idea and concept were great but let down by bad marketing.

Had they not used a tablet and called it the Wii 2 or Super Wii... then yes.

Edit: Also for the next release can we please have an option to rebind controls and being able to control the mouse (either with the touchscreen or holding the + button and then using the right analog stick + ZR/ZL)

It's a bit tedious having to exit moonlight and then having to use my phone to change between games (not all my games are on steam)

For everything else this app is marvelous, thanks for the port!
