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.

Let me know , if doesn't work we will try something else.....you are welcome

after 1 hour trying everything you said, nothing seems to work and still crashing after about 5 minutes, any other ideas?

Unfortunately Wii U moonlight it doesn't update as like other platforms does, and follow what brakes the new Nvidia drivers each time , the final user need to find the work around or stick with older or working drivers.... but you can try two other more things:

First test :

* Use DDU software to uninstall completely the Nvidia drivers (you should run in Safe Mode with your PC). Here it's the software https://www.guru3d.com/files-details/display-driver-uninstaller-download.html

* Once you uninstalled well the GPU drivers GeForce Experience and so on and restart your PC, download the latest driver installation from Nvidia Site and install, then restart the PC and run Moonlight service.

* This could fix the problem because on each Nvidia upgrades, the drivers could deteriorated and influence the functionality of such services.

If not solve with this first method, follow the below second method, that should work quite sure....

Second Test

* Follow this my guide on seventh page in this topic (here: https://gbatemp.net/threads/moonlight-wii-u.585995/page-7#posts)

Practically, you will install an old Nvidia drivers version that run well with Wii U Moonlight and block temporary the GeForce Experience to looking and install the upgrade automatically.
If you don't want the drivers version in that Seventh post, there is another newer drivers version that works with Wii U Moonlight it's in this post page (always my post) , here https://gbatemp.net/threads/moonlight-wii-u.585995/page-11#posts

With Nvidia GeForce Experience 3.24.0.123 for Windows 11 (there is also for Windows 7)....

Other Tips, keep the bitrate at 8000 and the Wii U base and Router be sure that are not so much far away from each other and that doesn't interference something between them, like a TV, thick wall, or too distance....

hello, after yesterday I tried everything EVERYTHING you told me (I even changed the bitrate trying from 1000 to 10000, changing resolutions, etc.)

In addition, the pc-router-wiiu are not separated by more than 1 meter from each other (they are literally in the same room) and the only thing that separates them is furniture, btw my internet speed is 30mbps, I will try with another router that I have of 100mbps

I guess I'll wait for some moonlight update to see if they fix the bug or maybe i should try sunshine?.... idk
Thank you very much for the help

Strange that still not working, because at least the rollback drivers it must to work!!!

If you are so sure that you made everything correctly, in this case you finished the chances with moonlight. The really last thing it's to use Sunshine. Also don't put the bitrate below 6000 because you can face the crash streaming as you face now.....

Ok, today I will try one last time with a 100mbps connection and changing the bitrate to more than 6000, do you have any guide on how to use sunshine? I've searched and can't find anything

@AlexCholo can you upload your current config here?

@AlexCholo try to change this:

## Video streaming configuration
width = 854
height = 480
fps = 30

And

bitrate = 8000



Let's see if we find the stability first......

Hi, I think I'm done with this, I tried everything with GFE then I changed to sunshine and it still didn't work crashing over and over again
I think it's just impossible or I'm cursed ahahaha

thanks for the support and help but this shit is beyond me.

This it's insane, thank you very much @GaryOderNichts , @aaronjamt and @ploggy , excellent job as always

Anyone has 1.3 working? Whenever I open it, it get's stuck at like 75% of moonlight.rpx and I need to turn off the WiiU with the power button.

I add the GFE IP to the config fail and also tried without it.

**EDIT**
Fixed it by going from Mocha to Tiramisu

 

[ploggy]

I made a Moonlight Forwarder Channel if anyones interested
Make sure you Moonlight RPX is installed in sd:/wiiu/apps/moonlight/moonlight.rpx (basically default location)
I've installed the Chan to nand on my WiiU and it seems to work fine

Hello,

Thanks for your great work with Moonlight Wii U! But unfortunately I'm having some problems, for example I need to have the computer screen on, if I switch off the streaming doesn't work, also I have some connection problem. At first it works fine but suddenly it stops or gives an error. Anyone has any of this issues?

I added an issue in Github: github . com / GaryOderNichts/moonlight-wiiu/issues/14

Thanks!

Rodrigo

The screen thing is a gamestream limitation not related to moonlight, it has always been like this.

Hi,

I didn't know that limitation, it is very awfull. Searching about this problem I found a fix in Nvidia Forum -> nvidia . com /en-us/geforce/forums/gamestream/19/226203/help-needed-using-gamestream-with-monitor-turned-o/2447912/

I think I will try it,

I think this limitation should be mentioned in the README @GaryOderNichts

Thanks

 

[Tryflin]

I'm sorry if this isn't the place to put this, but I'm struggling to get my wii u to connect to my PC. It gives me the error "failed to pair to server: failed to sign data". If y'all have any idea, it would be cool. Thanks guys!
