TurboGrafx-16?
Was there a system before the Turbo that had true stereo sound? I know that the NES didn't. Did the Master System have stereo sound?
By the way, when was the Master System released in Japan? I know that the Turbo hit in 0ct. of 1987. That was the first system, that I know of, that has stereo sound, but maybe the Master System did?
