Help gamepad orientation

Hello I am new and recently I met this emulator .

I have trouble setting up the display and buttons .

I want to play in full screen and in horizontal, the screen as I 've managed to set it up like after a few tries, but my problem is in the controls.

The controls are vertically me or comes by default as the emulator and it is very difficult to play well and I can not find the option to view the controls as horinzontal .

I wanted to ask aid you if I can say what the indificada option to " rotate " the controls.

Thanks.

P.S : Sorry if my English is bad.

I forgot to mention that I have the stable version 1.2.2 .

The overlays usually have an onscreen button for changing between portrait and landscape, often it looks something like this: https://github.com/libretro/common-overlays/blob/master/gamepads/retropad/rotate.png
