For NDK you have to play with the background4k.png and background.png. Or you can just rename them with .bac extension. Then you will only have background_color.png.As a side note, I installed for kicks the NdkBootPicker plugin, very easy to install. However, it would not scale to 4K. The internal bootpicker does scale properly. @cdf @h9826790 @startergo any setting I missed, beside:
Code:<key>Drivers</key> <array> <string>NdkBookPicker.efi</string> <string>OpenRuntime.efi</string> </array> <key>PickerMode</key> <string>External</string>
