I am using a new 3DS with A9LH and 11.3.0-36E. When I use picodrive, I think there is some kind of vsync issue, as I see tearing, but only in the top 5% of the screen. I am using the latest nightly version and have used various others. Does anyone know how to solve this? Also, I try using Genesis plus GX, but it's sometimes stuttering and alsmost like a horizontal and vertical tearing of some sorft, unless you play around bringing the menu up and cancelling it.
