@trihy: just to be sure, in the latest revision of master branch, have you changed certificate extension to .pem?

Hi, not sure about that, do I need to change the six certificates files to .pem extension? Before or after installing them?

Thanks.

edit. tried to change all of them, but still 20100.

From the Wii Network Guide:

Quote:Download the extract_certs.exe program. Drag and drop the 00000011.app you got from NUS Downloader (IOS13) onto the .exe for the program, and you should see three files appear next to 0000001.app: clientca.pem, clientcakey.pem and rootca.pem.
[...]
Copy these three PEM files to the User\Wii directory in your Dolphin folder. After this is done, you should be able to access the Nintendo WiFi Connection with Dolphin! Enjoy.

If you're still using the certificates dumped with the unofficial wiicertdump.exe, you should try dumping them again, I wasn't able to connect with the certificates from wiicertdump after wii-network was merged to master...

oh... I was using the old method Sad

The extract_certs.exe works great with master branch. Online is working, no more 20100 Smile

Thanks a lot Big Grin

I edited the first post to link to the official guide instead since it's now live.

Great, the official guide is pretty clear.

Quick question but does anyone have issues getting added friend codes to show up on their friend roster? I followed the official guide exactly and everything Nintendo WFC wise works except this. Is there something else I'm missing here? I double checked my firewall and router to make sure doesn't get in the way as well.

On Mario Kart Wii the friends codes doesn't work. You need a friend who has a Wii and can open a room in order to play with someone with an emulator.

Ok but how would I even join the room then ? Hard to join a room if the friend codes don't work
