After much experimentation, I finally got a combo that seems to work:
Skin: Titanium Blue
Size: 1080i or 1080p
UI: Normal Horizontal (3:4)
Nothing else works. Buttons either don't anything, or they're simply missing. In some cases, the screen just flashes when buttons are pressed. I wish I knew why the other skins don't work.
I'm happy I have SOMETHING that is usable. Now, onto creating some more orbiters.
