The Impossible Just Happened: WFC on DeSmuME

**Luigi__** · April 18th, 2010, 12:31

Update.

I did post this thread as some kind of bragging about DeSmuME's wifi capabilities (mostly worked on by me

).

But it appears that we got noticed at Nintendo's side and they took a first measure to block us. Of course, this is bad.

Because of this, WFC will now stay blocked until we get "perfect" enough to not get noticed again at Nintendo's side.

DO NOT ask why WFC doesn't work. Now you know.

Edit- if you wish to test DeSmuME's wifi capabilities without using WFC, you can still give the DS browser a try, and there's also a lot of dswifi homebrews that should work.

When I started the emu after recompiling it, and Windows Firewall popped up, I felt great.

Testing out the few games I have. Hope it will work, but... GREAT JOB desmume's coders!

EDIT: aww, during the test connection via the Pokemon HG rom, it says that there's no signal at all. Maybe I've done something wrong... I used the internal DeSmuMe firmware.

Um, the Windows firewall warning shows up when using Adhoc. Did you set everything right in the wifi settings dialog?

Forgot to change it. Now the AP can be viewed, but connection test fails saying "Unable to obtain an IP address"; during game, when I tried to connect to GTS, the strenght signal was good, but after a while, it went red and the connection failed.

However, desmume's coders are making progress, surely the wifi support will grow!

I got that error too. I manually entered IP and DNS settings as I had to do for my real DS, and I got another error code (52100: "impossible de se connecter à la CWN", or "unable to connect to the WFC"). I even got 20103 as well (maybe because I didn't allow DeSmuME both inbound and outbound... but now I'm getting 52100).

I'm guessing it could be the router/NAT blocking the connection, but I don't have time to check that now... Blame that to the end of my holidays...

The emulator connects over your bridge adapter that should already be set on the router, so I think that is not a router problem.

Luigi, how do you connect to the Internet? Modem, router connected via ethernet or wifi?

I couldn't get the WFC Infrastructure mode to work either(no IP address). Has anyone tried Adhoc though? Maybe we can finally trade pokemon and stuff with one PC.

if youre using r3538 or newer youll have to go in wifi.cpp and comment out the call to validatePacket(). I have blocked access to nintendo's servers by default until we can get some kind of consensus on how to proceed.

Oh, ok. Thanks.

Edit: Zeromus, does local wifi/adhoc work, as well? Just curious. Thanks.

Edit2: Commenting out if(!validatePacket(packet,len)) return; didn't seem to help..darn.

Do you think is illegal to connect to the servers with the emulator?

EDIT: nevermind, found it.

Most wireless adapters are not compatible with WinPCap due to driver limitations. It would be a good idea to add a notification dialog on the emulator to notify the user when this happens (if that's not done already).

most wireless adaptors are not compatible. virtually all wired adaptors are. wired adaptors should work with desmume wifi. softAP doesnt care whether or not youre using wifi. there should be no difference.

I don't think it is illegal, but I am not particularly eager to open up a new front in a very old war. Playing single player games from the privacy of your PC doesn't cost anyone anything, but once you start touching/glitching/cheating/griefing nintendo's servers in previously impossible ways, the costs start mounting. With the DS, they can't roll out software patches with tweaks to their security like PC and big consoles can.

Understood.

Anyway, I tried to comment out that validatePacket line, but I'm still getting the Unable to obtain IP error. Maybe it's because I connect to the router with a wireless adaptor that is not compatible with Winpcap?

edit WIFI_LOGGING_LEVEL in wifi.cpp to get more diagnostics.

r3538 is now blocking WFC connections. We are studying and discussing the potential risks of WFC connections (didn't we already do this?). We are probably going to put in a warning and ask the user for confirmation, rather than just blocking anything (not to mention, if we do that, DeSmuME being open source, anyone can release hacked builds with WFC unlocked...).

****ing goddamn token I have to copypaste my post and go back and reload the thread again why does that forum use tokens that expire >_<

I was ecstatic when I updated my local svn copy earlier today and saw changes had been made to wifi.cpp

Just tested out the "Wi-Fi Plaza" on Pokemon Heart Gold and it works perfectly. Nice job, guys (especially Luigi).

Dax · April 19th, 2010, 01:27

I finally got it to work, and Mario Kart just times out at the race start, as expected. Pokemon battles take forever to communicate. I'm still impressed though. Nice work Zeromus, et al..
