Whether lurking on an older firmware, banned from online activities, or unwilling to fork out for Nintendo's Switch Online, a lot of us find ourselves stuck in the void of single-player gaming. The release of switch-lan-play opened doors previously closed, allowing us to play a select list of games online regardless of bans and subscriptions. Taking another step forwards, we have ldn_mitm: a custom kip to break the final chains, to allow almost every game supporting local wireless to be enjoyed online.

Requirements:

1. Atmosphère 0.8.0+ SXOS 2.5 Beta+
   
2. switch-lan-play (setup guide)
3. ldn_mitm

How to Use (Atmosphere):

1. Download the zip from the release pages.
2. Extract the zip to your sd card,
3. Boot up Atmosphere with fusee primary.bin
4. Start your game of choice, and select local wireless play
5. (Optional) Use official Switch-lan-play discord to match make and find other players,

How to Use (SXOS):

1. Download the latest SXOS. Here
   
2. Go to SX Menu then to options.
   
3. Enable ldn_mitm,
4. Go in-game and select the Wireless Play Option (If you see an L in your WiFi bars that means that the kip did not load and that you need to reboot)

You can find a list of currently tested games here.


It is recommended to only use ldn_mitm and lan-play.exe from their official releases, third-party apps and homebrew are not supported.

Among us seems to work and have been added to the game list,

It is a pity that Among us requires connecting to CDN and having Nintendo Switch Online. Hopefully they can modify it so that it skips the CDN as they did with the YouTube APP, so it will not require Lan Play (although I suppose it will be the most played game with Lan Play).

Tried different servers, running it as an admin, checking the router config and connecting my pc to other wi-fi signals but still doesn't connect at all.
Also tried without the mtu set to 1500/--pmtu 500 to test other games than Animal Crossing and it still doesn't work.

Is it the firewall, something wrong with the PC or the Switch?

Im getting this same issue. Did you figure it out?>

You can play with people with an unhacked switch if the game has a lan mode you can find a list here:

Does ldn_mitm 1.7.0 work with firmware 12.0.0 and lastest Atmosphere 0.19.0?

 

[masagrator]

If someone needs - compiled with newest libnx and atmosphere-libs. Dunno if works. Compiled on request from other people.
Should work with Atmosphere 0.19.5.

 

[Davycrockof]

any way of going the other way? have local play pop up under online games? to force games to support local play
?

This is an idea not easy achievable, something you need to put ton of work for game on game basis.
