Virtua Racing (Genesis)

The Genesis Virtua Racing is a unique port of the classic racing game using a chip known as the Sega Virtua Processor, which makes polygon drawing plausible on the humble Genesis. Unfortunately, Sega later released the 32X along with an enhanced version of the game, which was far better than what the SVP had to offer. As a result, no other game uses said chip, though prototypes of a handful of 32X games indicate they were going to.

SVP Test Mode
Game Genie code or Pro Action Replay code  will force the game to boot into a test mode. If the game does not detect the SVP chip, it will spit out a communication error. Otherwise, it will check the integrity of the SVP and make sure everything is working.
