Thank you! I wonder how these were ripped. I've got a GNR Pinball at home and noticed that the vocals are separate from the music. Did he rip the other tracks aswell? Or if anyone knows how to do so, I'm willing to give it a try.
Well i got these back in 2006, as far as i remember he did something with the circuit board's soundcard - it wasn't 'line in', but something similar to computer game chiptune ripping:
