Yeah I will stay on 6.2.0 until there is a game I want which requires 7.0.Depends on what you want. If you really "need" that update for Mario Party than update your EmuNAND to 7.0.1. But check if all homebrew application which you are using works with 7.0.1 before. I would stay on 6.2.0 if you don't "need" it but that's what you need to decide.
Then I will just update emmunand with choidujournx as you said.
