During the game's prototypical stage, the team built a replica of the "Crescent Island" course from "Diddy Kong Racing" to test whether a racetrack of the same scope and scale was possible on the PlayStation. To address the complication of potentially having up to 64 kart tires on a four-player split-screen, programmer Greg Omi developed a method of rendering the tires as camera-based two-dimensional sprites. The turbo system that gives the player boosts of speed during power slides and by gathering hang time was added to make "Crash Team Racing" feel more interactive and involving than older kart-racing games. The central antagonist character Oxide was never intended to be playable in the game due to the PlayStation console's memory limitations. Said limitations further affected the game's roster of playable characters; Polar and Pura were originally to ride in the same kart and be played as a single character, but were ultimately split into separate characters, and both Komodo Brothers were to appear in the game before Komodo Moe was omitted.
