Amazing! I finally gave this a try (not expecting to be able to connect properly) and it worked! I have to set the IP manually each time but WOW! Now I can lay in bed and change songs on my computer!
Here is a screenshot that I accidentaly took while fiddling and listening to Shining (Swe).
Thats what I wanted to do on my ds as well change the song on my pc. Also, what flash cart do you use to run this homebrew?
