If the game is played on an original Nintendo DS console, Mario will say "Wahoo" on the opening screen, but if played on a DS Lite console or later, Mario says "Here we go!" instead. This is due there being a random number generation system that is intended to choose two sound effects from a pool of two each, the aforementioned two Mario sounds, and two car sounds - one of a car revving up and another of a car zooming past. However, due to a fault in the programming, the number is instead determined by load time, resulting in only one sound effect each, with the original "fat DS" only having variance in Mario's voice due to it having very slightly slower hardware, and the car zooming past sound effect becoming very rare compared to the rev-up sound effect.
