Two requests from the comments, for dual-screen devices such as the AYN Thor:
- The CRT filter now covers the second screen too. With Settings → Display → CRT filter on, the bottom screen gets the same scanlines, phosphor mask and vignette as the game, at the same line spacing. It's a little lighter than on the top screen, because there it is drawn as a see-through layer.
- New: Settings → Screen → Second screen buttons. Turn it off to hide the Menu / Save / Load / Speed / Battles / Battle+ bar. The panels then fill the screen and the controller does everything. It's on by default, so nothing changes unless you turn it off.
Tested on the AYN Thor in the field and in a battle, with both settings on, and with the defaults.
