so I was reading this article http://www.marketwire.com/mw/release_html_...lease_id=167704 about a portable karaoke device and was thinking how perfect this would be for a DS homebrew app. Seeing as how the DS already has a built in mic and headphone jack, you could easily turn the DS into a portable karaoke machine. Just hook in a pair of speakers to the headphone jack, perhaps some can hardmod the Nintendo DS headset with mic to accept a regular mic, and there you go. Make the homebrew able to play MP3's and allow user created lyrics to appear on screen. Get cracking coders!
