Disclaimer:
This is kit is for advanced installers only. I am not held responsible to damage to your console or damage to the kit. Each kit is personally tested by me and confirmed working before being shipped out. This document assumes you know how to take apart the gamecube with a gamebit tool as these instructions will not be included.

This kit uses Zero Force Insertion for the FFC cables. If you are not farmilar with these please visit this site for a visual aid. FFC connectors are fragile and can be broken easily if care is not taken.

For scart To hookup RGBS you will need a SNES mutlitout cable with a sync attenuation resistor inside the cable. Depending how you wire the QSB will depend on which cable you need. But most users should need a CSYNC cable like these:

5.3 and later Revisions:

Both types of scart cables are supported. If you cable has an attenuation resistor inside, then make sure JP2 is closed/shorted. If your cable does NOT have an attenuation resistor then make sure JP2 is open. These cables with attenuation resistors are still recommend on 5.3 and later.

To Hookup HDMI you will need an HDMI mini cable. I recommend this one on amazon: https://www.amazon.com/AmazonBasics-High-Speed-Mini-HDMI-HDMI-Cable/dp/B014I8UEGY/

Step 1. Don't skip this step. Make sure you know how the jumpers work.

Decide how you want to wire the GCDual up the analog port. There are jumper pads on the QSB PCB that will allow you to route signals to different locations. Click here refer to this document to understand the jumper settings. This document also goes over required steps for PAL consoles and NTSC consoles wanting to use the CHROMA and LUMA pins.

You're done

If you don't get video, try another tv. If still no luck enter the trouble shooting section.

Trouble Shooting

Most issues are related to the QSB installation on the main board. However here are some basic troubleshooting steps.

First setup the gamecube so its possible to run the without the case on.

You can do this by removing the motherboard and laying it on the heatsink. Then you can remove the power board from the case and plug it directly into the motherboard. It will look similar to this. Now you are able to power the unit and test without constantly taking the machine apart and back together.
When video does appear you will get an error message at bootup, don't be alarmed, this is because the there is no dvd drive. Also don't let the unit run for a long time like this. Becareful as you are messing around with a live power supply. I'm not responsible if you fry your Gamecube.

With no video problems boot up and see if the led is off, solid or blinking.

With your specific issue in mind, check your QSB and the corespoding points. You will need to do: check for shorts between points, reflow connections to make sure there is good contact.

If you have issues with audio, as in no sound or garbled audio. Verify points LRCK, ADAT, BCLK are connected properly.
