About SongFace there are like three versions on Aminet. I think I maybe tried the first or the second and the third wasn't working -just maybe-. This is what you can get while playing a song with SongPlayer: https://lh3.googleusercontent.com/_w...wItcanLook.jpg
. Yes, it includes an option for Karaoke.
It tells you how to create its MUI screen -and you learn a lot with it- and it opens it with scope and background, different letters and so, but it has some problem depending in what image you use. You can try it and read the readme.
Anyway SongFace doesn't play mods, but maybe it's posible to configure another player in a similar way.
