How to customize turbo? 1. Press the TURBO switch on the adapter. 2. Then press the button that you need to customize (any of button A, B, X, Y, L and R). 3. Now you finish customizing the TURBO function. Release the switch on the adapter, but keep pressing the button that you set just now. The LED on the adapter will light up, which means the button is successfully customized with TURBO. 4. Repeat the above steps to cancel the TURBO function. 5. Any of button A, B, X, Y, L and R can be set or cancelled individually or in batches. 6. All settings will be deleted automatically after un-plugging the adapter from your Wii Remote. Note: Add a new cable converter that makes the NES/SNES/FC/SFC to Wi Adapter compatible with SNES 7 pin and 9 pin controllers at the same time.
