    How to change retroarch.cfg resolution and ratio?

    what is the line? the screen is below the bottom of the screen by several pixels and its ratio is 1:1 and not 4:3

    thanks for your help

    I think you need to add this line to retroarch.cfg:

    video_aspect_ratio_auto = false

    According to the retroarch.cfg config file:

    If this is true and video_aspect_ratio is not set,
    aspect ratio is decided by libretro implementation.
    If this is false, 1:1 PAR will always be assumed if video_aspect_ratio is not set.

    Here is the rest of the config options for retroarch.cfg for reference:

    The person in this thread: http://blog.petrockblock.com/forums/topic/force-43-screen/ said setting video_aspect_ratio = 1.175 gave good results. Or you can change it in the emulator (if it’s a Retroarch core) by accessing the GUI, think it’s f1 if you’re using a keyboard or you can map it to your gamepad/joystick in retroarch.cfg with:

    input_enable_hotkey_btn = "**" 
    input_menu_toggle_btn = "**"

    (the stars are where you specify the buttons on your controller)

    If you have found the solution to your problem please mark the topic as resolved.
