What's the problem? Describe what went wrong.

So in Netplay build 5.0-321, if you go start up a netplay room and put yourself as multiple ports, the only port that will respond is port 1. The only way to get them to respond is to go into the controllers menu and place the second, third and fourth port as "Gamecube Adapter for Wii U." However, in addition to not responding, Port 2 will hold down B, while Port 3 and 4 will input and hold down on the control stick as well as the Z button. In previous builds, this did not occur, and you didn't even need to go through the controllers menu to get the ports to respond.

What steps will reproduce the problem?

Step 1. Open Dolphin

Step 2. Click the Tools Tab

Step 3. Click on Start Netplay

Step 4. Click on the Assign Controller Ports button

Step 5. Click on Ports 2, 3 and 4, and from the dropdown list click on your own name.

Step 6. Click the Start button

The ports from the Controller Menu must be "None," for the other ports.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

Dolphin 5.0-321 is the build I tested this on, as well as Dolphin 4.0-7840. It did not occur on Dolphin 4.0-7840.

What are your PC specifications? (CPU, GPU, Operating System, more)

Don't really know what you need but:

Processor: AMD Phenom(tm) II X4 945 Processor 3.00 GHZ

Graphics: NVIDIA GeForce GTX 460 v2

OS: Windows 7 Service Pack 1

It's probably not enough but I don't think it's very relevant anyway.

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

No.
