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.

hey, if i use kosmos (atmosphere...) when i need to put the latest ldn_mitm ? (or when i found it) please ??
Thanks You

iirc kosmos has the ldn_mitm already integrated by default,
You need to enable it via kosmos toolbox to use it i think,

What do SX OS users do. If you enable the online option in the SX menu, load smash & go to the local wireless & it gives an error?

Try again later?

Or maybe check you have the network configuration right.

What's probably happening is that too many people are playing that game. Try with a different game to see what happens.

Thanks! Was told, apparently they never updated the local wireless KIP? So smash for SX users, is the only game that doesn't work with. For SX users at least.

You tried with latest SXOS beta to, but still same error?

Yup! Tried as soon as i saw they dropped a new update. Still same thing. Local wireless works IF i don't turn on the option in the SX options menu, but with it on i always get the same error.

Same thing is happening to me. I think im going to try and use atmosphere instead. Wish me luck!

It'll work, as long as you aren't on 8.1.0. Apparently, sys modules need to be updated to support that firmware.

 

[SG911]

Yeah, I was told by someone that SX guys need to update something still. On there end at least so that smash will work. Cause apparently other games work using SX & the local wireless feature. Just not smash.

Where do we put the .kip file for SX OS?

SX doesn't support kips. Lan play is built in. It's in the setting somewhere. Same place as FPT transfer and stealth mode toggles.

 

[oBluEx]

Ok so. I wanna say I have everything right.

I'm using Atmosphere 0.8.8 FW: 0.7.1, booting CFW with the Fusee_Primary. I'm using a fresh install just cause.

I made a "kips" folder under my atmosphere folder, it sits next to kips_patches. I placed the ldn_mitmv1.2.3 under my new kips folder.

I also placed the contents of the zip in its correct places.

My internet settings and Lan program are all perfect.

Now if i got to Local Wireless in Smash. I'm using 3.0.0 so it should work. How can i tell I'm all setup? Is there a way to tell that kips is working. Under the .nro it says it's on.

Hello everyone, I may need some help.
I toggled the ldn_mitm option on Hekate Toolbox, asked me to restart, and now I think it's bricked cus I can't get past the Nintendo Switch splash screen.
I'm using EmuMMC so Sysnand still works fine.

so far I have replaced the atmosphere, bootloader, config and switch folders to see if it fixes, but nothing so far.
Could anyone please tell me what to do now?

 

[mattyxarope]

Has anyone tried this with Friday the 13th yet? Afaik it doesn't have LAN mode...

 

[OddFWGKTA]

Awesome.

--------------------- MERGED ---------------------------

i just want to know if i can play online (with local mode of course) with my friend in other country with his legit switch and legit game With me with my switch hacked and banned ??

No, that won't work.

 

[Cubuss]

Ldn_Mitm updated to support latest Atmosphere
https://github.com/spacemeowx2/ldn_mitm/releases/tag/v1.2.6

 

[RedBlueGreen]

Has anyone tried Pokémon Let's Go more recently? Haven't followed this in a while so I don't know if the API was figured out.
