Road Fighter (set 3, conversion hack on Hyper Sports PCB) is a unique version of Road Fighter. The description indicates it's a conversion hack, meaning it's an unauthorized modification of an existing game's code to make it run on different hardware.  In this case, it's adapted to the Hyper Sports PCB (printed circuit board). This would likely involve technical expertise to alter the game's code to adapt it to a different platform. The hack's existence suggests creativity and technical skills, though its legality is questionable. The gameplay would remain largely similar to the original Road Fighter.
