I don't think he's talking about the audio tracks, more the course design.
Exactly.
I just want to see the layout of the 5 missing racing tracks.
2 I now have, but 3 are still eluding me.
Maybe in the future someone can recreate the tracks.
Who knows maybe I get bit by the bug and do it (slim, next to non-existing chance).
The BS broadcasts had live CD quality sound with live commentary, so the real audio tracks might possibly be heard in some videos but the original digital tracks probably only exist only in Nintendo HQ.
