Just bought Magic Dosbox and installed it on the Shield TV. Is there any chance of implementing some visual indicator of what game / menu option you are selecting from the main screen on Android TV devices?
I noticed in an old video it looked like you could enable a blue cursor that was controlled by the joystick. Pretty much everything else can be setup so that you only need a gamepad once the options are configured, so I found the lack of gamepad support on the game selection screen to be the biggest obstacle toward using this as an Android TV app.
