this game broke ground being the best port over the saturn and ps version as this was a 32 meg game and had an extended graphics chip making the super nes more powerful with its own processor chip . flip it over look at the chip and you will see on each side extnded by a quarter of an inch on each side there was a handfull of games using this chip stunt race fx and super mario rpg to name a few . this game has a hard time running on retron knock off systems and classiq 2 and 3 systems you will need original hardware
