I have yet to do a 3DS graphic, I was waiting on the ability to have independent aspects on the dual screens. While that feature is here now, and I will be doing a graphic, the dual screen preset is in heavy development. If anything is going to break in the future it will be that preset.
I don’t have, nor will I be doing, NDS or 3DS vertical screen graphics for landscape displays. (I just don’t feel it makes any sense.)
I have a fairly large set of portrait display graphics, including an NDS. Again, I was waiting for the new release/features of Retroarch before doing any 4K Vertical presets. They will come after I finish the advanced.
I also have to do a full set of Hybrid presets.
