I got the keyword “overlay”. Thanks a lot!

Hi Ifan, I had used overlay to show background image. in retroarch.cfg input_overlay = “:\overlays\my_bg.cfg” input_overlay_opacity = “0.300000” input_overlay_scale = “1.000000”

in my_bg.cfg overlays = 1 overlay0_descs = 0 overlay0_full_screen = true overlay0_overlay = my_bg.png

But it is input overlay. It will draw in front of my game screen not draw in back of my game screen. How do I set the background overlay not input overlay? Thanks a lot


The overlays are in front of game screen… I think they were created for cellphone to have the joystick buttons on the screen.

I think so. Thanks for your help.
