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.

Thank you very, very much! you are THE BEST

Pokemon sword and shield has a lan mode so you can play online without ldn-mitm,
This will also make it more stable , To enter lan mode go into options menu and pres L + R + Left Stick,

Welp, that was pretty well hidden even compared to the other games lol. Thanks for the heads-up!

Anyway, I've made a PR on the repo not too long ago - hopefully it'll get accepted so theory leak will get fixed nevertheless ^^

Is Sword and Shield when using this still disabling 90dns? Or has there been a fix found yet?

 

[MonMonz]

Any tutorials as its my first time using this for sword and shield?

Very glad to hear about the lan mode in pokemon. About sxos and ldn_mitm I don't think the fix is needed at all, I used it until yesterday and played for hours and even joined some raids and never got any error. But will be better to play in pure lan mode at this point.

Don't quote me on this one, but afaik SX OS integrates an older version of the plugin that might have been built before the bug was introduced, so that's probably why you're not getting the issues.

Anyway, the PR got accepted and a new release is coming!

SXOS works if enabling LAN-MODE in Pokemon, do not enable Local over Internet option, it's not required
Have fun.

I just wanna report that ldn_mitm caused my Pokemon Shield to freeze everytime a save was injected with Checkpoint/EdiZon. After deactivating ldn_mitm the freezes disappeared.

hello, I wanted to ask how do I setup this? I did put the files on the sd, but what I have to do now? and, how do I disable switch lan play if I want to play local wireless? thank you

 

[MADokax]

I mean, its impossible to play local wireless if I have the files on the sd!?

 

[RadsammyT2]

Holy fuck. I don't have a Homebrewed NS, but this is amazing.
Thanks, OP. Will use it for when I get my RCMloader.

Does this work with Earthfall?

Trying this with Sword Art Online Fatal Bullet and I don't think it works, it just crashes when you try to create an adhoc lobby.

Hi, i have setup my lanplay in both my switch and pc client (using the latest official release of ldn_mitm and lanplay client) but it doesnt seem to connect, anyone know what i miss out or what is the issues ? I get this error details (refer picture) every time i tried to connect, the pc client not showing any log on my switch connection.

I am on Ver 9.0.1, AMS 0.10.2 + hekate.

 

[Cubuss]

Newest version should fix the crashing with Diablo 3 (Always make sure you are using latest ldn_mitm)

Animal Crossing - New Horizon Seems to be working so its been added to #game-list , and a room is made : #animal-crossing It requires some custom settings for now tough in order to be able to join people: You need to go to your switch internet settings and set MTU to 1500 And you need to run the lan Play Client with the --pmtu 500 Flag .
