Hey guys,
I have been considering getting a Japanese Karaoke unit but since i dont have a NTSC-J dreamcast it will have to sit in the box until i get the j-spec dc. I know people are saying to only buy it if you are a serious collector but i want to make the most of it. It seems like an SD card reader would be handy to have.
This is what i need help with...

-Who has one?
-Does the GD have any songs? (some sources say that there are no songs supplied but others say there are pre loaded songs on the disc.)
-could a homebrew disk be made with the right software?
-tell me about your experiences with it
