Broken GameCube Microphone

[Narigaur]

So I plugged in my GC mic into the card slot on my Wii to play some Mario Party 7 with it (seriously, playing with the controller is so frustrating) but when I went to go test it in the settings menu, I'm not getting any response out of it. There are no red bars on the screen, and yes, I'm holding down the button. I tried pressing harder, but it's not working!

Is that microphone designed to work in only ONE particular card slot (some devices work this way)? I never used one, so I don't know if you can use it in either slot, but you can try using it in the other card slot and see if it works. Also, can you read a GCN memory card in both card slots to confirm that the slots are both working?

After that... It's kinda hard to suggest diagnostic options without knowing your skill set with such things.
