Miniturbo
The miniturbo, or mini-turbo is a speed boost technique present in every Mario Kart game.
Overview
When performing a drift, assuming you are using manual transmission, a miniturbo will charge up after a certain period of time, and when you release the drift, you will get a boost from this miniturbo. Miniturbos charge at different rates depending on the joystick direction held during the drift. Although the GCN joystick has an input range from 0 to 255 on both axes, all inputs are simplified and reduced down to an input range from 0 to 14 on both axes. These are also referred to as -7 to +7 to ease understanding even more. Miniturbo charge is a numerical value that counts upwards from 0. If you are performing a right drift, any input from -7 to +2 will increase that value an increment of 2 every frame, and any input from +3 to +7 will increase that value an increment of 5 every frame. Conversely, if you are performing a left drift, any input from +7 to -2 will increase that value an increment of 2 every frame, and any input from -3 to -7 will increase that value an increment of 5 every frame.
Types
There are three types of miniturbos in Mario Kart Wii:
Standard Miniturbo
This is the most common type of miniturbo. It is charged when miniturbo charge counter becomes greater than 270, and is possible on both bikes and karts. Upon reaching at least 150 charge, individual blue sparks begin appearing at the back of the vehicle the next frame.
Super Miniturbo
This miniturbo is only possible on karts. Beginning on the same frame that the standard miniturbo is fully charged, a new super miniturbo counter begins counting from 0 up to 300. It is charged when the super miniturbo counter becomes greater than 300, and individual orange sparks appear the frame after the charge counter reaches at least 180. The player may be tempted to release the miniturbo after a standard miniturbo is charged, but should they continue to hold the drift for slightly longer and orange sparks will appear, indicating the longer miniturbo.
Standstill Miniturbo
This miniturbo can be charged by holding accelerate and brake (A and B) simultaneously when IV is between -10 and 10. This increments a standstill miniturbo charge by 1 per frame until it becomes greater than 75, after which the standstill miniturbo can be released.
