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.

Hello @GaryOderNichts, on next 1.4 Moonlight version could be possible to give a missing little future?

Practically it's to give to the Touch Screen the future to open the Right Click Menu from the "Remote Desktop", it's like if you hold pressing for 3/4 second the Touch Screen it will appear the "Right Click Mouse Menu".
This will be really nice to open the "Right Click Mouse Menu" to move the things around and fully manage from The Wii U PAD.

Use the GamePad touchscreen for mouse emulation

How did I miss this?
NOW UsendMii is truly done for good. Thanks everyone!
That gamepad will make a perfect drawing tablet for notes and such...
Also DS and 3DS emulation!

how to stop streaming? which combo button?

how to stop streaming? which combo button?

hold home button for more than 3 seconds

I even tried a different network.

did it end up working or did you just give up?

Has anyone tried multiple controllers through the wii u? Like using a wii pro controller connected to the Wii U to play the pc game?

 

[Yot-C]

I always get "Can't find app Steam" error as soon as I try to stream sunshine. Steam is installed at the default location on C:/ so not sure it has not been detected yet?.

Finally installed this with Sunshine (I have a Nvidia MX230 but GFE doesn't like it and Sunshine falls back to the other embedded video card, whatever) and I'm loving it
Any suggestions for desktop usage? Any useful settings?
It would be great to have it as a second screen for writing and reading my schools notes (eg with One Note), I think I can make it work with the current touch system and by adding some button mappings, but I see you made some commits about absolute positioning
Can we have a test build? @GaryOderNichts

Can confirm absolute mode it works as expected
(But maybe the path to the config file should be relative )

I hacked something together to install a fake monitor with the right resolution and have sunshine stream it, and now I have a free windows tablet

Sorry for telling you this only now, but could you add a shortcut to kill the client if it crashes? It happens at least once a day, and I have to reboot the console... the "press the home button for tree seconds" doesn't work when it freezes.

Also a gui to edit the settings from the console would be nice, right now I have to exit the app and FTP the new configs.

Just wanted to say thank you for the update! Steam games work very good, but is now also possible to start the Edge browser and play Xbox Cloud games! Halo Infinite on the Wiiu

Hey,
I tried Moonlight Wii U a while ago but didn't stick to it because I didn't have a lan adapter (I was getting bad performance and/or green bar) so I was using it on my laptop which worked great.
Now I have bought a used nintendo lan adapter (official) and 720p is working great but it looks a little too pixelated on my tv and 1080p30 still is a choppy mess... Any idea what settings I might use ?
When I use my laptop connected to the tv I stream at 1440p60 and it works great (with a bitrate of 80mb which should theoretically be covered by the 100mb speed of the adapter). I know it will never be like that but I would at least like to have a good experience at 1080p30 on the Wii U...
Thanks !

Hello It says it can not find app steam
{
"env":{
"PATH":"$(PATH);C:\\Program Files (x86)\\Steam"
},
"apps":[
{
"name":"Steam",

"output":"steam.txt",
"prep-cmd":[
{"do":"steam \"steam://open/bigpicture\""}
]
}
]
}
Even after I changed the name. Is there something else I have to change

In geforce experience, in settings, under Shield, you have to add any software you would use and rename It "Steam" (or change the name in the config file)

Getting a 'Can't find app Steam' error as soon as I try to stream. Same thing on both sunshine and openstream. Steam is installed at the default location on C:/ so not sure why it's not detected.

I know this is late but do you remember how you did this and how you fixed it?
