This tutorial was started on April 1st 2011. Its about enabling WIFI feature for NDS Games playable on DeSmuMe v.0.9.7 if you have broadband connection using Wired-LAN (Ethernet LAN Cable Broadband) without any WIFI router or access point; not possible on USB Broadband Dongle, or Dial Up via telephone cable; maybe possible via wireless connection but I'm not covering it. As long as you have Ethernet Wired-LAN Connection and Ethernet LAN hardware in your computer (PC/Laptop) as well as using router; it should work. I first learn about this thanks to Lune's tutorial thread in GBATemp.net, all credits goes to him/her for bringing it up. If you are using an internet connection method other than Ethernet LAN Cable, please refrain from trying as it won't work. For Win XP users, run the program as normal, for Win Vista and Win 7 users run the programs in ADMIN Mode. Mac and Linux.....well....don't ask me about it as I don't have either program. I have confirmed that the below method work on both my Windows XP Home SP3 Laptop and on Windows 7 Home SP1 Laptop. What you need: 1. DeSmuMe WIFI Package (Choose 1) 1.

High Speed Ethernet Wired-LAN (Broadband) Connection Optional: 4. Save File Convertor : Offline Save File Convertor from Evan Dixon Shunyweb Online Save File Convertor UniqueGeeks Save File Convertor * Note: Use this only if you want to convert your game save file from DeSmuMe type to use on your Console's Cartridge, or if you want to download contents for your game save file from your Console Cartridge via DeSmuMe. Pre-Setup: 1. Installing WinPcap After downloading the packages, run the program, make sure to tick "Automatic Start at Boot time", also make sure that its marked as "exception" in your FireWall Settings. Note: Do not ever disable your FIREWALL and ANTIVIRUS !!! Unless you don't mind getting virus/trojan/malware all over your computer. Which is more precious and important? Your computer and its files or playing games? Just give the WinPcap exception and do the same to DeSmuMe. Give both FULL CONTROL/ADMIN RIGHT under PROPERTIES in the SECURITY option. 2. Setting Up the DeSmuMe Run the DeSmuMe in the package; # Large Image in the Spoiler: Spoiler a. Go to CONFIG and choose WIFI SETTINGS, then tick INFRASTRUCTURE and then press OK As for the bottom INFRASTRUCTURE SETTINGS, it depend on what hardware you have in your computer, so you have to test which one will work for you, should be the one for Ethernet Wired LAN that will work. b.

If none of the below possible trouble shooter work, most likely you will never be able to get the feature to work due to your internet subscription package type. 1. Try replacing the firmware.dfc in the DeSmuMe folder with either one of this: a. Firmware.dfc Option 1 : Click Here Option 1 b. Firmware.dfc Option 2 : Click Here Option 2 (Thanks to : John3 a.k.a John2461) 2. If some of you are using VISTA or WIN 7; a. There is DEP (Data Exchange Protection) security in the system. To by-pass it for DeSmuMe and any other software/program. * Right Click on the DeSmuMe icon on your Desktop * Run as Admin -or- * Right Click on the DeSmuMe icon on your Desktop * Properties * Security * Edit Permission * Full Control b. Move the "biosnds7.bin", "biosnds9.bin", and "firmware.bin" into the Firmware Folder before assigning them as instructed in the tutorial. (Thanks to : Insanecrazy07) 3. You might want to attempt editing the DNS inside the WFC Setup config to : 126.96.36.199 188.8.131.52 4.2.2 4. Go to Network Connection, manually changing the bridging from PPOE to PPOA (or the other way round) 5. You might want to attempt editing the IP inside WFC Setup to : 192.168.110 or changing the last 2 digit to any number in the "10" multiplication; eg. 192.168.120 ,etc. 6. Locate in your Control Panel's Firewall, for any possibilities of a setting that might block the WinPcap (eg. disable SPI Firewall). There's no need to disable your firewall !!! 7. Make sure your LAN Connection is set as HOME Network, not work or public network. 8. If you get Firmware.dfc,BiosArm7.dfc, and BiosArm9.dfc, image error, go to PATH SETTING under the DeSmuMe's Config, and self assign the files/folders. Or alternatively, self replace the firmware.dfc with the one provided above. 9. Assign STATIC IP ADDRESS for routers that has both ethernet cable port and antena(WIFI anthena). 10. Go to DeSmuMe main screen and press CTRL-R to reset your settings, or perform a RESTART computer. 11. Make sure the WinPcap (rpcapd.exe) and DeSmuMe are in the exception list of your Firewall and Antivirus. 12. Try to clean up your network adapters. Uninstall/disable all the VPN software like Hamachi, Tunngle, VirtualBox, and VMWare Workstation, etc. and reboot your computer. You can also try to make your network adapter that is connected to the internet to the primary one. To do this, go to the list of your network adapters and press ALT then click "advanced" --> "advanced settings" highlight the adapter and put it to the top with the arrows. (Thanks to: Ultravore) 13. If you have trouble getting the GTS, PGL and Game Sync to work between 2 friends. One of you (or both) may try to change your router settings: enable UPnP is a must, beacuse a DS needs all the UDP ports forwarded for the connection to work (this info is available on the Nintendo troubleshooting website). If you still have problems, you may have to change your router. (Thanks to: Shadow-5471) 14. Make sure to check if you computer is running on x64 bit ot x32/x86 bit. 15. Make sure your network is set to use LAN Broadband (Local Area Connection) not Wireless. 16. Make sure you are the only computer connected to the router-modem. Side Note Regarding Save File Conversion If you want to use the downloaded WIFI stuffs on your NDS Console, simply convert the DeSmuMe's save file into the appropriate save file type for your cart, and name it the same as your game rom's name. It should work like a charm as I've already tested it too. If you have an on going game play on your console and do not have WIFI router/access point in your home, you can also make use of the above to download contents over this feature by converting your save file to DeSmuMe's save file type using the convertor, run it like the above, and convert it back into your cart's save file type once you've done the download.

I've decided to remove all images that was hosted in PhotoBucket due to them blocking it each month for a week as they expects me to go pay even though I didn't used up my free quota. 2. Given that some of those who come to use this topic don't seems to understand that I don't support wireless connectivity, however there're several posts made by nmp0401 in pages 56 - 58 for that purpose. Read them if you must. 3. Also given the numerous similar and repetitive problems that kept popping in this topic, I find that it's a waste of my time responding to the same issues over and over. I suggest those of you having problem to go read the over 60 pages worth of posts. It shouldn't take an hour to skim read through them all than wait for my response. The solution you probably looking for is sure to be among those 60 pages.
