Homebrew WIP [Official] switch-lan-play

[Shubshub]

Works surprisingly well.

Is there any chance this can work with Super Mario Party?

That's a significantly more complicated issue that you make it sound, because "local wireless" is switch-to-switch with no wireless router. Sure, with a WLAN device in monitor/promiscuous mode that can both capture packets from a switch and broadcast packets recieved over the internet you can do that, but that's a whole new thing and out of scope for switch-lan-play.

PPP should be the least of your concerns here. It should be "what kind of hardware does everyone need to standardize on" for such a thing in the first place, as well as how to identify and capture switch-specific packets so we can even relay and replay them in the first place.

I was meaning more like this:

Custom sysmodule catches the attempt to put the device into local wireless mode. Presents a virtual interface instead. The game works exclusively with the virtual interface, not the real wifi chip.

The virtual interface accepts the datagrams from the game, and packages them as PPPoE frames.
The ACTUAL network stack forwards the PPPoE frames to a remote host, using some kind of session control to establish the PPP handshake.
The remote unpackages the encapsulated datagrams, and presents them on its own virtual interface as incoming datagrams.

The game does not know it is not using Ninty's proprietary wireless as the physical layer.

I'd assume such a thing is viable, but I haven't looked up/into how the switch handles local wireless mode. How easy such a thing is would depend on whether the OS handles local wireless or the application.

The primary advantage of switch-lan-play right now is that it's a no-KIP solution. That's the context I was thinking in (no KIP module.)

NO.
This game doesn't have LAN party mode. Only Local Wireless mode.

- Once again - this list is about LAN games, not Local Wireless. Difference is, "Local Wireless" is Wi-Fi ad-Hoc connection between nearby switches. LAN mode uses your existing home/office/school/whatever network you use.

Spoiler: LAN vs Local WI-Fi image

- In most cases "Local Wireless" is default option and "LAN" has to be activated on certain screen by variation of certain key combination usually requiring pressing left analog and bumpers - [Left Stick] + [L] + [R].
- Some games had LAN play delivered as an update hence game might need update. Please note especially if you have only XCI game you might need NSP update. Please do not ask here to get them from.
- All players need the same game version - I mean game update, not region.
- f you turn local connection or however game mode is called and you get changed WI-Fi icon with "L" shaped symbol -

- it means you have entered Local Wireless mode, not LAN mode.

Thanks to everyone who contributed!!

SPLATOON 2 (always requires latest patch to run)
Press [Left Stick] + [L] + [R] at the local play option - it's called "The Shoal".
Hold down until screen goes black and Wireless mode is replaced with LAN mode.

MARIO KART 8 v1.0
Press [Left Stick] + [L] + [R] on the main menu screen.

MARIO TENNIS v1.2
Select Free Play from the Main Menu
Press [Left Stick] + [L] + [R]

POKKEN TOURNAMENT DX v1.3.3
This one is tricky.
From the very main screen where game asks to "Press [L] + [R] to start":
Press + [X] + [Arrow Down (either digital or analog stick)] then add [L] + [R]
New screen asking if you want to enter Event Mode will appear.

ARMS v1.1.0
At the main menu screen:
[Left Stick] + [L] + [R]

Titan Quest
Start game as "Multiplayer - Local"

RetroArch (Homebrew apps)
They simply work via tunel as part of your LAN

No news if the lan play for Android will come out?

 

[Captain_N]

To ban no monster hunter. guess a ad-hoc emulator is needed

You can alreade use it on android, just use the linux binaries and install terminal emulator on your android(must have root)

Sweet. I will have to try this.
If anyone wants to try that does not have root, it might be possible to run a Linux emulator on the phone.

It would be nice to have a GUI
The GUI would just have to work the terminal commands (you would need root if that was all the GUI did tho)

 

[chaoskagami]

I figure I'll mention this since running things like this as root is a dumb idea...if you're on Linux (maybe Android, but selinux might get in the way) and don't want to run this as root for security reasons, you can also (as root) grant the binary the needed capabilities instead and run it as a regular user, which is far more secure (if any sort of RCE vulnerability exists, they won't be taking over your whole system):

sudo setcap cap_net_raw,cap_net_admin=eip lan-play
./lan-play

Why do we have so many servers? I dont think too many people are using this at the moment so it would be a good thing to have one crowed server to find some people to play together? Just tried to find some partner for a match Mario tennis without luck.​

Are you serious?
If I want to play with friends I set up own server close to them in the middle of Europe, not joining some random aDSL one I the USA.
This is tunnel of LAN, not online service. You want to have packets travel as near as possible. Not to go through the other hemisphere of the globe.

Can I play Monster Hunter with other players with this?

 

[jakkal]

Hopefully an Android version gets released so I can play on the go while tethered

why

 

[S3phi40T]

why

Because there is no "LAN mode" but only "local wireless"?

I am hosting a server for australians 24/7, if you want to jump on for good ping shoot me a msg here or on the switch lan play discord - username "lithium"

Does smash have a lan mode? Is it confirmed?

 

[Cubuss]

We don't know yet since lan mode would not be something Nintendo would announce in a direct,

We would have to wait until the game releases , but my bet is that it will have a lan mode,

 

[fst312]

Based on the latest direct smash bros supports lan. I thought Nintendo would make sure they punish banned users like me and not allow lan support for this game.

 

[Cubuss]

Bayonetta 2 apparently also has the lan mode added to the list,
To enter lan mode:

"Enter tag climax and highlight local play then hold left stick and press L+R"
