Danny Sullivan’s Indy Heat Unreleased Sega Genesis

Danny Sullivan’s Indy Heat is origionally an arcade game which also saw a release on the NES and Amiga. It featured four-player capability, and was similar in gameplay to Super Off Road. Players earned money based on their race finishing positions, which was spent on improving their car. The race season culminated with the Tradewest Speed Bowl, which loosely resembled the Indianapolis 500.

Apparently it was ported to the Sega Genesis, but never saw an official release. Now, the proto has been dumped to create a limited run of 50 copies of the game.
