Any volenteers to code/program this?, please, I want this too

CD+G (sub-channel) Karaoke-CD support request

I would love it if you added support for CD+G (a.k.a. CDG Karaoke) to libcdio, ie reading the text/subtitles from the subchannels. CD+G discs are much like CDDA discs with CD-TEXT support, the data is normal CDDA Audio-CD but hidden in a sub-channel/sub-code is the song-lyrics graphics data and the timing to display them.

Some (if not all) technical/developers information on CD+G can be found here:

BTW; Nero, CloneCD, Alcohol and CDRWIN can all both read and write CD+g discs,
you can also download MP3+CDG files and convert them to CD+G discs:

Projects where you could potentialy get source code:

FYI, there is also something called CD+EG (CD + Extended Graphics, a.k.a. CD+XG) but that is not as important

PS! The reason I personaly want CD+G support in libcdio is for XBMC (Xbox Media Center) which uses libcdio, it's been asked for there before but no one has had the skill to implement it (plus on the Xbox sub-channels are only supported by Samsung DVD-ROM drives).
