They were just the default settings when I setup Emudeck a week or two ago. I did setup RetroDeck too as I liked the more containerized nature of it, but it seems to run an older version of Yuzu (has a different, lower number in the window name) and even when I mirrored the settings of my Emudeck version it was pretty stuttery and crashed at least once.
But I can look at my settings and share later today.
How cool! I had the manga when I was a kid and absolutely adored it. Totally forgot that it existed.
