// Interesting findings from original NES Super Mario Bros.:
// -Clouds and brushes of all sizes are drawn using the same small sprite (32x24)
// -Hills, clouds and bushes weren't placed manually. Every background object type is repeated after 768 pixels.
// -Overworld (main theme) drum sound uses only the APU noise generator
