Why the Nintendo DS screens grew on a book-shaped foldable

Holding a foldable like a book made the Nintendo DS touch screen small in the old layout. We moved both screens to the center and the controls to the sides to make more room for touch.

In 1.1.0, unfolding a foldable put the game above and the controls below. Turn it so the hinge runs vertically, though, and fitting both Nintendo DS screens into those two halves becomes difficult. The lower touch screen gets especially small.

Version 1.1.1 adds a layout for this posture. The two Nintendo DS screens sit large and stacked in the center, with the D-pad and buttons at the sides. The touch screen is about twice as wide and twice as tall as before.

L and R, Select and Start, and the microphone and Pause buttons sit above the D-pad and face buttons. This keeps them within reach of the hands holding the device while leaving more room for the touch screen.

The layout applies to both the iPhone Duo and Android foldables. Turn the device another way and the screen follows the new orientation. We checked the layout in an iOS simulator and an Android emulator.
