What's the problem? Describe what went wrong.

While 1080 Snowboarding Avalanche and Mario Kart: Double Dash work correctly

What steps will reproduce the problem?

1: Have two separate computers on the same LAN - Localhost does not work as the BBA ports will conflict.
2: Start Kirby Air Ride with BBA (Built-in) enabled.
3: Connect both instances to the game's LAN option at roughly the same time.
4: Kirby Air Ride will see the other GameCube and attempt to connect and then error out.
5: No further connections will be attempted until you manually cancel searching and retry, where the same error will happen.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

The issue has existed since 5.0-16838, which is when the built-in BBA was added.

Is the issue present in the latest stable version?

Technically no, as this option did not exist.

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

Core i7-7700, GTX 1060m, Windows 10
AMD 5950x, GTX 1070, Windows 10

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

I connected my Laptop via LAN to see if it was instability issues. While that did slightly improve things (the connection was made faster and on both ends) it still errored out at the same point.
