We added initial support for the Nintendo GameCube Microphone accessory. The microphone shows up in gc-linux as an ALSA sound card with a PCM capture device, so it is ready for use with the existing standard Linux audio tools. You can get the code from the recently revamped cvs service (http://gc-linux.cvs.sourceforge.net/...ux/sound/ppc/). As a quick-hack, we've prepared a poor man's karaoke kernel (http://prdownloads.sourceforge.net/g...k.dol?download) for you to test. Don't forget to have fun!
