is it possible totrade with yourself by starting the desmume system twice and using a diferent black/white version (to avoid havign the same id), or would that cause problems considering the fact that you'd be connectign from the same accesspoint, on the other hand 2 brothers who play the game on ds would also connect from the same accespoint seeing as they would live in the same house, but still two ds' connectign from the same accespoint could be different from 2 emulators connectign from the same computer
so do you have an idea if that would work or if i should avoid trying it out?

It doesn't work with same save file.Gotta use another sav file.With another save file, it works.I've tested.(One from white and another from black)

According to Maxmahito, he had tested what you are asking and it work for him; able to trade. If I recall correctly he used 2 different pokemon rom, one running pokemon black and the other running pokemon white; but likely ran on 2 computers. This is so that the friend code that is generated be different. But I personally have not tried, so I dare not give any firm answer. You need to add the friend code of each version into each other so that the 2 detect each other.

Troubleshooting error code 52100 from Nintendo DS WebPage:

Error Code: 52100
Our experience has shown that this error message is typically caused by a basic setting in your router, such as transmission rate. Please carefully read the instructions below:

Check Nintendo's router info for special notes, if available, for your router.
1.Click here to go to our Wireless Router Configuration page.
2.Use the drop-down box on the left to select, if available, your router manufacturer.
3.Click on your router's model number, if available.
4.Read any "special notes" at the top of the router's page. Many issues can be solved by changing settings described in the "special notes."

Another device may be sharing the same I.P. address of the DS. Try manually assigning an IP address to your Nintendo DS.
1.The first thing you'll need to do is find out the range of IP addresses you should be using. To do this:
1.Click the "Start" button in the lower left-hand corner of your computer.
2.Click "Run."
3.Type "cmd" into the box and press Enter.
4.Type "IPCONFIG/ALL" and press Enter. The IP address of the PC will be displayed.
5.The IP address you are going to assign to the Nintendo DS must be 10 digits higher than the PC's. (e.g., 192.168.1.100 becomes 192.168.1.110).
6.Enter in the exact same values for your Subnet Mask, Default Gateway, Primary DN S and Secondary DNS as you see listed on your computer screen for IPCONFIG/ALL.
2.You will now need to manually assign this new IP address to your Nintendo DS. For step-by-step instructions on how to do this, please click here.

Ensure you have entered the correct DNS into the DS's manual settings. You can verify this by using the steps listed directly above (IPCONFIG/ALL).

Troubleshooting other error code (A Big Thanks to Lune of GBATemp.net)

Error on Win 7: BEFORE ANY OF THE FOLLOWING MAKE SURE THESE THINGS ARE DONE FIRST:
-Again..have a wired connection by a cable (lan cable)
-Run desmuME as an administrator
-"For anyone getting 'Unable to get IP address' or 'Unable to connect to Nintendo Wi-fi network' errors, you need to check your router firewall settings. I use DD-WRT and an enabled SPI Firewall will not allow you access, disabling that let everything work fine.(by Forumpost)
-Disabling any firewalls that you think would be blocking the process...
-WINDOWS 7/WINDOWS VISTA users must go to network and sharing center and make sure that your connection type is set to HOME network and NOT PUBLIC OR WORK(work may work but meh)
-In the Wi-fi settings in desmume make sure it is set ton infrastructure mode and also the correct bridging is enabled with your ETHERNET CONTROLLER (your network adapter)

Emulator doesn't save: You would have to go into PATH SETTINGS and set your own paths for screenchots,cheats,roms,saveram etc.

Error Code 52000/52001/52002: Check your modem status and change it from bridging to PPPOE or PPPOA(sometimes work).Also double check the WEP key you entered(if used).Make sure if your on windows 7 that you have run the emulator as an administrator and also check that it's connection is an exception in your firewall/antivirus software

Error Code 52100:There could be Ip address conflict going on...you will have to give your ds its own ip address rather than using dhcp to find its own..check HERE
for help on doing that(too long to type..)

Yes, that works from 2 computers.You can do it from one computer too, with GTS.But not when both the emulators are turned on at the same time.
LONG story:
I turn on desmume.Call it DS 1.
Then I turn on desmume again(so that I can trade simultaneously at the same time as asked).Call it DS 2.
Now, you got to GTS centre first on DS 1.
So, you'll not be able to connect to GTS again with DS 2(Since, the acces point desmume uses is SoftAp which has EXACT same coding for every emulator).
As you say, two brothers from same access point can do.But we can't.
Nintendo DS gives out the encoding for access point different even if they are from same point.
Since desmume is an emulator, it has a SET value of code to allot to an access point(SoftAp) and since you're using the same access point in your system, nintendo WFC server recognises this and blocks your network from DS 2.
Hence, "no network error" occurs when two desmume are emulated simultaneously.And Therefore, Desmume discourages and removes wifi ability from it's official release.Because if nintendo finds out desmume is behind the so called "SoftAp" access point, they'll be doomed.

SHORT Line: You can't trade with two desmume at the same time from same CPU.If you have a single CPU, deposit the pokemon in GTS from black rom and quickly(very quickly) turn on(load) the white rom and go to the GTS, search, trade and enjoy.
WARNING: Don't blame me if you are unlucky/slow and loose your deposited pokemon in GTS(black) to another person before you can trade it with GTS(white).You have to be very fast and lucky.
How to douse the problem in warning?
Use desmume's SAVE STATE before depositing the pokemon.

I hope you understand.I know I didn't write it out clearly so that everyone can understand, but I've tried my best.

Infra Red is for sure not going to work cause DeSmuMe does not emulate IR function. But for Wireless...you can make use of the entralink feature (I've not tested the other function found in the wireless option in the C-Gear). I've tested playing in the dream world. I planted a berry and harvested it, and made friend with a pokemon in the dream world. That new pokemon and item when you wake up, can be retrieve at the Entree Forest inside the Entre Link area.

To play in the dream world, you need to do :
1. Create an Account in pokemon-gl.com
2. Do GAME SYNC from the Main Menu to get GAME SYNC ID to use also in the pokemon-gl.com registration
3. Turn on C-Gear and go ONLINE to make a pokemon sleep
4. Go to the Dream World in the webpage at the same time while doing step 3
5. After the intro and info, you get to play in the dream world and transfer whatever item or pokemon you get to your save file.
6. Get the pokemon/item by going to the Entree Forest via EntraLink that can be access from the C-Gear's Wireless option. But you need to be within the EntraLink network for the feature to function.

** Doing all the above might be time consuming depending on how fast your internet and computer. It took me more than 3 minutes to do step 2 - 4 before the pokemon finally sleep and show up in the webpage's dream world. During play in the dream world, best is not to switch off the DeSmuMe. But of cause it will slow down your computer's processor with both DeSmuMe and webpage running at the same time if your computer spec is average.

Works for me too.But, horribly slow.(Dunno why, though.The game's speed has beed reduced drastically during saving or connecting from the time I started using wi-fi on it.)

Max, thanks for explaining how you did that hit and run method.

Have you tried doing;
1 computer running pokemon white, set the IP address for the SOFTAP, 10 digit more so that to avoid error code 52100 (see my post regarding solving error code 52100; above your post), while the other computer running pokemon black, in normal. By avoiding the conflict of using the same IP address, maybe you can do the trading without that 'hit and run' method you describe in the above.

E.g. In the WFC SETTING;
Computer 1 (auto aquire IP/DSN in the WFC settings) : lets say the normal/original IP 192.168.100 and DSN 192.168.100
Computer 2 (Self input IP/DSN in the WFC settings) : set the IP address to 192.168.110 and DSN 192.168.110

I've not tried it myself. As I have only 1 cable line for the LAN. So to run 2 computer online at the same time I have to do an AD HOC method. By connecting the LAN cable to the Win 7 computer, create an AD HOC sharing network wireless, and make my Win XP computer link to it via that AD HOC connection wireless. Which of cause I've not tested running 2 DeSmuMe at the same time. So I've not verified it myself regarding this self-trading method. But maybe that will help get the 2 computers to run on the same SOFTAP and avoid conflict.

Bandon gives a good solution about that to speed up playing online while in pokemon-gl.com.
1. Run the DeSmuMe and do the Game Sync via C-Gear's Online feature to put a pokemon to sleep
2. At the same time sign in into your pokemon-gl.com account to register that sleeping pokemon
3. Of cause during the above 2 steps, the process take time around 3-5 minutes or more depending
on your computer speed
4. Once step 3 is done. Close the DeSmuMe. This will save the RAM from hardwork allocating the
memory for use on both DeSmuMe and the WebPage's flash game. Thus makes playing in
the webpage more enjoyable by having the DeSmuMe turned off.
5. Once you're done playing and want to send or wake up the pokemon or send it back with some new
aquired items/pokemon pal. Do step 1 and 2 again.

I've tried it after reading your suggestion.But, Changing the IP adress by adding 10 and keeping the DNS and Mask/Gateway constant is leading to error 52100 again.I'm not encountering the error with Auto Obtain option, the connection is OK.But, with manual IP as suggested by you, it gives me the error code 52100.But, if one has two computers, why to go through all this trouble? The hit and run method was for a single CPU and a single file.With 2 computers, one can have two friend codes from two saves and use them to trade/battle in Wifi-Club room.

Dream world is loading and processing fine.I can play it normally.The slownes I was telling about is for In-Game(saving, talking, battling etc.,).I'm sorry, I didn't clearly mention that in my last post.

Oh, really? You got that error when running 2 DeSmuMe on 1 computer when trying that method I suggest, right? I was suggesting about doing it on 2 computers going through 1 connection line (this suggestion is based on the fact that I don't have a router and only 1 LAN line). I'm thinking of trying it out, but remembered that I've only got 1 save file from Pokemon White which would mean the friend code would be the same. If I was to start playing Pokemon Black too or start a fresh game on Pokemon White for the sake of testing the self-trading....well....it'll take lots of time and effort to reach the entralink network area.....which I don't fancy of doing at this point, too lazy. Playing this 1 save file on pokemon white alone is getting a bit boring by the day, let alone start a fresh game on black.

Edit: Been spending most of my time reading e-books on the NDS handheld lately. Surely, you've noticed my other tutorial is about turning the NDS into an e-book reader.

Yes, i got that with 2 Desmumes on single CPU.You need 2 computers one connection? I've got two computers, two connecions.Don't know how to get the line out of one connection for two computers, sorry.

Well you can, by creating a wireless AD HOC share connection. If lets say you have 1 win 7 computer and 1 win XP, you use the LAN cable on the Win 7 computer, create the WIFI AD HOC connection via Network Connections, switch on the XP to start detecting the AD HOC broadcast, enter a passkey, and there you go....1 LAN connection for use on 2 computers, and the best part is, you can have many computers to link up using this method, including compatible devices. But not able to connect to the NDS console, as its not compatible.

1. Make sure he's using Ethernet LAN Cable connection not other method
2. If he had tried on the SVN 3963, try the SVN 3947 (the link is in the first post). As running on the newer SVN version is rather tricky.
3. Troubleshooting that error code see my reply #80, its copied from Lune (he/she is the original thread creator for this topic in another site)

**Only for use to WIFI AD Hoc connect several computers and compatible devices by turning your Win 7 laptop into a virtual WIFI hotspot transmitter. Cannot be use for connection with NDS/NDSL console is its not compatible. Cannot be use to connect between 2 DeSmuMe via this Ad Hoc method.

Has he did all the steps as stated in the tutorial, and allow the winpcap in the firewall? And make sure he assign the 2 Arm Bios file and firmware bios in the Emulation Setting. The method is pretty straight forward. Make sure to remove the other SVN copy to avoid conflict.

PS: Reply #80 is the one marked with blue "troubleshooting" writing. Its only a few post above this.

Where would you find DeSmuMe v.0.9.7 r3963 x64 for windows 7??
I see the link but it only gives me the x86 version. Im getting 52000 and I think thats the problem. I disabled everything, and everything is perfect.
I even did it for my friend and it worked, although he had 32bit. So if anyone could give me the link to the 64-bit of DeSmuMe it would be really helpful.
Thanks in advanced.

You can find it here: http://www.emucr.com/ for the latest SVN versions for 32bit and 64bit, the latest to date is SVN 3989, but you can find the SVN 3963 you're needing from that site also. But you'll still need to download any of the package I provided to grab the Arm 7 Bios, Arm 9 Bios, Firmware Bin, and the WinPcap files. As those 4 files are not provided in the original download.

Note: All the files and programs are not made by me. I'll update the downloads in page 1 when I find
time to start uploading it. Really sorry cause at the moment I haven't the time as I'm really busy.

That's strange. Maybe there's something that you had missed. Cause the steps in the tutorial is already the proper method and should have shown no issues, and I've even elaborate further in the posts. Thus I have ran out of further advice to provide on this issue of yours. Best is you check and recheck what might you had forgot doing or try solving by trial and error.
