I am unable to find a guide that talks about the routes for GCN, which has made it hard to learn. If anyone has a guide, that would be very helpful.

Heya, there's this guide by Chrix from 2018 https://hobbitspeedruns.com/guides/any-percent-nmg-console-chrixiam/introduction It's not completely up to date but it's in depth and shows alternate strats if you need them.

Sorry for the late reply, thank you
