This has been bugging me for the last 2 years. When I got my gamecube, i turned it every which way to learn everything about it. When I looked at the ports on the bottom, I was perplexed. I had done some research. Serial Port 1 is for internet adapters. Hi-Speed Port is for the GBA player and a rumored hard drive from IBM. But I am still confused on the purpose of the 2nd serial port. It seems so tiny, and almost useless. Can someone shed some light on what this damn port is (or will be) used for?
