Thanks for the reply! I'm not familiar with the Carby and retrotink 5x though

Is this the Carby? CARBY- Nintendo GameCube Compatible Digital Audio/Video Adapter (Clear with Remote) https://www.amazon.com/dp/B083YPCQZ8/ref=cm_sw_r_apan_glt_fabc_6M9FPRD7141W3C0Y387A

Couldn't find the retrotink 5x on Amazon. Is there a good guide on where to get these parts or which things I need? Sorry if this is obvious but I'm new to this, been using the old AV cables all these years haha
