I did my search on the subject but I haven't find much information, and the information I found left me more confused so I hope someone can help me out:

I know linking 2 Desmume for Pokemon Black/White is possible (Same computer).

I know Accessing WFC is also possible via emulator.

Although it's not possible to trade using Wifi or more precisely the Friend Codes, correct? I ask because some people say it's possible through a WIRED connection. This was all done with Pokemon Black and Pokemon White both on emulators. Are there any known cases, or would it be possible to a similar "link" between a game like Pokemon Diamond and Pokemon Black? Be it through Wifi,wired connection or Emulator-DS connection?

Thanks!

To communicate between PC and DS, you need a Wifi card based on Ralink RT2500 chipset, and use a custom firmware for the card to convert Wifi to Nifi (it's a wifi without the TCP layer).
Nifi was used to send data to the Download play menu of the DS, and was known as Wireless Multi Boot (WMB) or as Wifime method (named after the physical device passme method).

Wifime has been patched by Nintendo starting on NDS Firmware v5 (DSPhat with backlight setting, the version just before the DSlite, and DSlite share the same firmware).

I think wifi communication ingame can still be done, check 2nd url bellow.
Though, I think there's no program to manage data between computer and DS.
The only way to send data is through the Download play menu, other than that it's just some technical data that nobody used.
SGstairs tried to make a tunneling application to play "DS download play" games through internet, but his project was never released.

Some informations :

Nifi drivers works on windows Me, Xp and 2k, I can upload them to filetrip if someone want them.

If the emulator can somehow get onto Nintendo's WFC (I don't use NDS Emus but this seems doubtful to me) then it can trade with the DS via that.
Or, an alternative is to dump your save using SaveGameManager via FTP, load the save in your Emu, trade, then dump the sav back to your cart using the same program.

It is possible. I have done precisely one Pokemon trade myself. Although I am not sure if the other guy was also using an emulator (doubtful) since we never met face to face. There were a number of hiccups. For instance, I tried to contact him but he didn't reply. After I stopped the request, I got d/ced. Reconnected and this time, he contacted me and we managed to make the trade.

I think you might be confused on the whole Friend Codes issue. The problem about the WiFi on DeSmuMe is that the WiFi settings aren't saved. Remember that on a physical DS, you must use the same DS to access WiFi. If you use your game on different DS and try to access Nintendo WFC, the saved data of your online activity is deleted, including your Friend Code.

In DeSmuMe, since your WiFi settings don't get saved, everytime you exit then reload DeSmuMe, it would be as though you used a new DS. So your Friend Code keeps changing everytime you do that. It is a huge hassle for sure, but it doesn't make DS-to-emulator connections impossible.

Hey everyone- a quick question:

Is it possible to connect two computers that share a router to the Nintendo WFC simultaneously? I ask because I set up my emulator as per the instructions on this forum ( and my cousin's emulator) and tried out playing Pokemon black and white between the two setups. They both connect to WFC fine and can battle random opponents online, but when I try to battle or trade between the two computers the connection gets dropped before a trade or battle can be initiated.

Is this a problem with the router? the connection? the software? ALL I WANNA DO IS GIVE MY COUSIN SOME POKEMANS>>>!!!
thanks ^^

If you use iDeaS, you can get a wifi plugin. Just make sure it's in a folder called "PlugIn" <---- Just like that. I tried it. Pain to set up thou...

    @KenniesNewName That's the problem with gadgets, there's a new one being leaked, announced, released every week, and if you wait for something better to come along you can wait forever, there's always something new on the horizon.

    Same thing with price too. Miyoo Mini is $50 and it's fine, but RP2 is only $100 and has way more options, but now there's the RP3 and it's just $30 more, but the Ayn Odin Lite is $190 and it's very powerful, but the Ayn Odin Pro is $250 and it's an absolute beast, but now we're already in the Windows handheld range and I really would like a Windows handheld... Ayn Loki starts at $200, but why not add a few bucks for better specs... but now we're close to the Steam Deck and that is a much better choice...

    So we get from $50 to $500 in tiny, reasonable increments.

    My attitude in those cases is to decide what I want in that particular moment, not waiting for emminent releases. And decide based on function, that is, if I will use it almost daily and if it satisfies my desire/need
