I’m using Lakka 2.0 but unsquashed the SYSTEM file containing the LibreELEC OS. Is there detailed information about how rgui operates, or the menu drivers in general, with respect to editing their code/script/config and where the images are that they use? I’d like to have rgui use a transparent background image instead of the grid, or modify the alpha value it uses when a game is paused in the background so the menu background is completely transparent. Thanks.
I don’t think it’s something you can change at runtime. You would have to recompile with the correct changes.
You can do this at runtime with XMB menu, though.
