Troubleshooting

I can't connect to my friend's party!

WebRTC does everything it can to connect you with your partner, but things may fail on rare network configurations. In those cases, a quick workaround could be enabling a DMZ on one side.

I have stuttering issues!

Then you may want to increase the Buffer size, in Settings. Lower values offer less input lag, but they can produce stuttering if network latency is not low enough. Try increasing it until it works well.

Some games don't work!

Well, not all the NES mappers are supported. Feel free to raise an issue here with the game you're trying to run.

There's a crackling sound!

Make sure you have your speakers' default format set as 96000Hz at most:
