Just telling us something doesn’t work doesn’t give us much to work with. Here’s an example of the CargoBot screen as a background with a circle moving down the screen in front of it.

displayMode(FULLSCREEN)
supportedOrientations(PORTRAIT_ANY)

function setup()
    x=WIDTH/2
    y=HEIGHT
end

function draw()
    sprite("Cargo Bot:Startup Screen",WIDTH/2,HEIGHT/2)
    fill(255)
    ellipse(x,y,100)
    y=y-1    
end
