Switch between mouse (e.g. hardware mouse, trackball, etc), pointer (touchpad, touchscreen, lightgun, etc), or disabled. Switch between mouse (e.g. hardware mouse, trackball, etc), pointer (touchpad, touchscreen, lightgun, etc), or disabled.
* **TATE Mode** (disabled/enabled)
Enable if rotating display for vertically oriented games (Pac-Man, Galaga, etc). Requires `video_allow_rotate = "false"` cfg setting in RetroArch.
