In order to keep this bug tracker manageable, you need to keep a few things in mind:

*Is the issue already opened? Try out a search before filing one.
I have tried searching, but the results are quite different from what I want to ask.

Is your feature request related to a problem? Please describe.
It's irrelevant. I hope Lemuroid can automatically change to landscape mode when the phone is locked in portrait mode after entering the game, and can fill the entire screen. I hope Lemuroid can save the data in other directories.

Describe the solution you'd like
Lemuroid can be set to automatically turn the screen horizontal when entering the game, and the stretch ratio can be set, allowing Lemuroid to choose other folders to store game data.

Describe alternatives you've considered
none

Additional context
Introduction:
Mobile phone: Redmi K30s Ultra, Snapdragon 865, 8GB+256GB
System: Android 12
Lemuroid version: 1.16.0 Google Play
Handle: xbox handle 2020

Lemuroid allows horizontal screen and the screen stretch ratio can be set.

Vertical screen operation:

Horizontal screen operation:

There is a large area of ​​black undisplayed area in both vertical and horizontal modes, which is a serious waste of the small screen of the mobile phone. At the same time, I hope that Lemuroid can also be set to horizontal mode when the system is locked in vertical mode.

Xbox controller button related.

Default RetroPad R2=R2 Which button is this? I haven't found it yet, although I can set the "Share" button to R2

The Lemuroid controller button settings for the RT and LT buttons cannot be read.
