Last view: 2094 days ago 		Last night I spent hours trying to get trading working between two instances. I was almost giving up. The last thing I tried was an advice from a YouTube comment:

Turn OFF the frame limiter!

And it worked! Before with the frame limiter on, trading was extremely unstable, the Union Room bluescreened with almost every action. But with the frame limiter off, it works most of the time, as long as my two characters enter the Union Room about the same time.

Since I was having such a hard time finding this solution, I thought I leave it here:

I'm using melonDS 0.7.3 with Windows 10, my only network connection on my PC is my Ethernet internet connection (no wifi).
I copied the ROM file, renamed the copy, and renamed my second savefile to match it.
In melonDS Config->Emu settings turned Wifi: bind sockets to any address ON.
In melonDS Config TURN LIMIT FRAMERATE OFF!
Make sure both your saves have the Pokémon they want to trade and save them in a PokéCenter.
Restart both emu instances at once, enter the Union Room with both at about the same time.

As long as I followed these steps the trading worked, and was completely stable for me.

Frame limiter is set to off.

Wifi is set to bind to any address and randomize mac address. If I don't randomize the address, then the two instances can't see each other in the room

renamed the second copy of the rom and save file

The two copies can see each other in the room but can't get past the initial introduction phase. As soon as I attempt to talk to the other, it starts to negotiate and then kicks both out with an error.

Also tried disabling audio sync, that didn't help

Did you ever solve the issue? I am having the same issue with 0.9.1.

Last view: 1434 days ago 		I have played around with it a little more (Win 10) and tried various versions of MelonDS. I still haven't gotten it to work but I do get farther into the trade with some versions. Here are my notes below:
-0.9.1: BIOS1 - can't even start a trade, BIOS2 - can almost finish a trade
-0.9.0: BIOS1 and 2 can almost finish a trade
-0.8.3: BIOS1 - can't even start a trade
-0.8.2: BIOS1 - can almost finish a trade
-0.8.1: BIOS1 - can almost finish a trade
-0.7.3: BIOS1 - can almost finish a trade
-0.4: BIOS1 - can't even start a trade

I also have a old Win7 PC that I fired up but had worse results with the couple versions that I tried on it.

So I think I will concede defeat. The melons have won.

I have managed to finish 20 trades without an error. I opened 2 melonds instances in the same PC and disabled the frame limiter.

I'm really stupid.

How do I download this version? Or do I have to compile it myself?

Okay I figured it out. Turns out you have to have a github account to download the artifact. Didn't know that.

After downloading it, I set everything up and it works great. Was able to trade successfully multiple times with no errors on the same PC running 2 instances of melon.

I'm really hoping this feature makes it to 0.9.2, as long as everything works out with compatibility.

Nice that the SRAM PR makes Local Multiplayer more stable!
Does this work over LAN or are the timings too tight for that?

I tried this but it does not work at all. In fact it breaks before initiating a trade
I have tried all the settings like MAC address randomization, bind to any socket

Try running the game on 0.7.3 instead. It didn't work for me until I tried it on that version. Make sure to do what OP did by turning on bind to any socket and turning off limit framerate.
