GameCube Easter Egg - Famicom Disk System Startup

Notice when you turn on your GCN (Gamecube) with no disk in the system, it takes you to a menu that looks like a cube. On this menu, you can hear ambient sounds playing in the background. If you record this screen for a little bit, ( you need the audio.) and speed it up 16x in any basic program. You'll hear a little tune. That tune was actually the Famicom Disk System Startup theme. Nintendo made the Famicom Disk System in 1986, so it's cool that they'd add something like this to a newer console.
