I've been using this code:
</ label="Enable system logos", help="Select system logos", options="Yes,No", order=18 /> enable_slogos="Yes";
//System Logos
if ( my_config["enable_slogos"] == "Yes")
{
local slogos = fe.add_image("slogos/[Emulator]", flx*0.02, fly*0.913, flw*0.08, flh*0.05 );
slogos.preserve_aspect_ratio = true;
slogos.trigger = Transition.EndNavigation;
}
Just add this to your layout then extract the attached zip file to the layout folder and you can have the proper logos, just need to play with the x/y/w/h values to get it right in your theme.
