LoungeChair​

This application does not support voice chat at the moment.​

With LoungeChair, you can access Nintendo Switch Online game services like SplatNet 2 on your PC. All you have to do is sign in with your Nintendo Account. (Note: I will never be able to see your personal information or access your Nintendo Account. Source code for the application is provided on GitHub as well.)

Downloads

Go to the latest release page on Github to download LoungeChair. Please note that this program is in alpha and as such may contain bugs. Please report these on the GitHub Issues tracker.

FAQ

Will this application ever support Voice Chat?

Maybe. It is on the list of planned features, but it would require me to invest more time for reverse
engineering the voice chat protocol that the smartphone application uses. (... Anyone want to help? lol)

Where is the source code?

There are two parts to the application. The WinForms application's source code can be found at this location.
Source for the second part, which is a library for the Nintendo Account and Nintendo Switch Online APIs,
is located here.

too much work

you can't even do two clicks?
well i mean sometimes i get to lazy to move my hands to my keyboard to do ctrl+c/ctrl+v

 

[Kioku]

This is awesome. I'm wondering if Ninty won't do an official PC app. I've got everything running through my mixamp for sound. So, talking through my pc is more practical than a damn mobile device.

hmm, as far as I know it feels like splatnet 2 is just a webpage with cookies telling the nnid, it looks like a webpage with how it loads up

Looks really good, impressive!
quick question, since your window is named "Browser", does nintendo uses a web view in their application to load the online services?

You're exactly correct. Game services are loaded in a glorified web browser. (Additional info: The initial request needs a token, and the server sends a session cookie (in SplatNet 2, "iksm_session") back in response which is then used for the rest of the game service's session.)

The Question would be if the Server gets information about the User-Agent and stuff - since we know the Switch can transmit alot of data it should be double-checked.

Otherwise - nice1

Currently, the user agent sent to the server is "AccountsHelper/1.0.0 NASDKAPI" for all requests. The legitimate application is different and uses two different user agents. Additionally, it includes some other HTTP headers saying the platform (ie iOS or Android).

RIP no native Mac support
(Oh well x3)

It'd be nice to see if you could eventually make smth like this into a responsive webapp; while that kind of defeats the purpose per se, I'd like to be able to use my Online Services w/o having to use the app on my phone

Unfortunately, my Hackintosh installation and my MacBook are out of service, so I can't help you there.

I'm not really a webapp developer, so I think that would be for someone else to do.

<snip>

This error confuses me. It's literally something that should not happen at all. Does it still happen when you restart the application?

 

[incidentallyscribble]

This looks nice! It's great for people without phones. Has anyone tried loading the switch online app via bluestacks?

 

[Supercool330]

Fun fact, I already spent some time reverse engineering the voice protocol. The first part is receiving invitations, which appears to be done using Firebase Cloud Messaging, which unfortunately doesn't have a native client, but the browser client has typescript source maps, so it would be possible to implement a native client based on that (note that I'm pretty sure this requires an HTTP/2 push client). The voice chat is actually implemented in C++ and compiled to a native binary. Based on a very cursory skim, it uses WebRTC for the underlying communication protocol, and Opus for voice encoding. I find it sort of interesting how heavily Nintendo relied on web (browser) compatible technologies for a client they seem to only intend to release as a mobile app. Unless there is something big that I'm missing, a pure website implementation of the client should be possible (but would require a decent number of newer technologies such as Service Workers, WebRTC, MediaStreams, HTTP/2, and more).

Do you have the .NET Framework 4.7 installed? it probably missing some updated run-time libraries.

Impressive. Most impressive, but i have not the Switch yet.
Still impressive doh.

 

[OrGoN3]

Is there a reason why it would ban your account for using this? It doesn't really seem like there would be

Connecting to Nintendo services via non-Nintendo devices breaks their TOS/AUP. Thus, there is always a possibility for a ban.

Edit: So what exactly is this? Is it a clone of their mobile app? https://play.google.com/store/apps/details?id=com.nintendo.znca

Yep, exactly why I said I wasn't sure. (It would be a really shitty thing to ban for. Just block my application's access, Nintendo pls)

And yes, it's a clone (w/o voice chat) for their mobile app.

 

[Deleted User]

Just tried using it, keeps giving me a error with "resource not found". Have Microsoft .NET 4.7 installed and I went ahead and re-install just in case. still the same error.

 

[Marxally]

This is so cool! Works perfectly for me! Now I won't have to even touch my phone to look for the shitty gear.

Deleted and tried again, crash. Deleted and tried another account, crash. Not sure what to do or how I could help you on this.

<snip>

Okay, I looked into this. The only way I can reproduce this issue is if you use a Nintendo Account that is not linked to a Switch. Do you guys/gals have Switches linked to your account? (I hope so, otherwise what is the point of using this application lol)

Yep, it's linked alright.

 

[Keizel]

I can confirm that it works but only in english. When I use my smartphone, I can read the app in spanish.

 

[ogioto]

Isn't installing an android emulator on your pc waaaaay easier? It's not bad having a program for those, who can't or don't wanna deal wit emulators and stuff, but at least they could have developed more before releasing it in this state, even for an alpha...

PS: The upside of the android emu is that u can use it for a shit ton of cool things, beside the Nintendo app (like other cool apps/games)

It's written in C#, which means you can port it to Swift/Objective-C easily.
