This sounds extremely familiar to me. At first, I was convinced that it was one of the replay tunes for the Sega Saturn port of Sega Rally, but listening through the soundtrack for that game, I cannot match it to this melody.
I've tried asking in the chat multiple times but nobody has responded. I assume they don't know the answer. It's driving me nuts since it sounds just like Sega Rally, or perhaps another game for the Saturn from around 1995-1997, made by the same composer.
Or maybe it's something completely different, and I'm just leading you on the wrong track with my assumptions...
