There's a theme in Fantasy Zone which is used for the parts shop. It sounds a bit like this: http://www.youtube.com/watch?v=y9cy4Tp-ASk Fantasy Zone Gear has it too, and I imagine Super Fantasy Zone does if you enable the "classic" music. I came across a factoid somewhere which stated that Hot Rod borrowed it, which turned out to be correct. I figured it was just a bit of laziness on Sega's part with the idea that nobody would notice. But today I found something - the same tune is used in Turbo OutRun for its part shop. And it's also in Super Hang-On is this some crazy Sega tradition... do we know if there are any other games which borrow this theme?
