In Mario Kart 64, a Mini-Turbo is performed by executing a drift and turning the kart in the opposite direction it is drifting, then back again. (If drifting to the left, tilt the Control Stick right, then left again, while holding the drift.) If done correctly, the trail of smoke behind the kart will turn yellow. Repeat the previous step to turn the smoke orange/red, then release the drift to launch the boost. If the drift is held to the inside too long, the kart may suddenly go too sideways, slowing it down. The boost is not so noticeable due to lack of animation, but it's denoted by the driver shouting.
