For some reason, the item roulette sound effect in Mario Kart 64 has never been easily accessible on the Internet. To somewhat alleviate this, I have captured audio directly from Mario Kart 64 (in an emulator) and shared it with the rest of the world.
Please note that this still isn’t the best possible version of the sound effect, as you can clearly hear the sound of a kart engine in the background of this video’s audio. Still, this is a sizeable improvement from a certain crappy low-quality recording dating all the way back to 2011.
