GameCube Blue Retro Adapter User Guide

Pairing

Pair Mode is indicated by the top LED flashing from red to purple, and the port that is being paired will be slowly flashing.

When the GameCube is first powered on BlueRetro is automatically in pair mode

Upon a successful pair the port LEDs will go solid.

After a few minuets the pairing state ends. To reenable pairing mode later hold the reset button for 6-9 seconds, the front LEDs will be flashing fast.

Reset Button

The reset button on the console has been converted to offer new functionality based on how long you hold the button down. While it is being pressed the front ports will light up to show which state you will be enabling.

Holding for 0-3 seconds will perform the same action as on a stock console, reset.
In this state all four front port LEDs will be solid on

Holding for 4-6 seconds will disconnect all connected Bluetooth controllers 
In this state all four front port LEDs will be slowly blinking

Holding for 7-9 seconds will enable pairing mode
In this state all four front port LEDs will be blinking faster

Holding for 10 seconds or more will factory reset to the original firmware and remove any custom configs
In this state all four front port LEDs will be blinking rapidly

When the system is placed in power down mode the reset button will wake it with a single press.

If you power the system off with the main power button, and hold reset while powering on the BlueRetro adapter will be in sleep mode and will not interfere with the console use this in the event that a peripheral is not working nicely with BlueRetro
