What you have would work, however the sprite size is 16*16 for width and height, also the sprite never loads because @HOMESCREEN is an infinite loop. And RETURN won't ever be called, let alone it won't work because it must be paired with GOSUB. Lastly, you are scaling the sprite to be 20 times it's original size, making it take 320 pixels on the screen, but Y only goes from 0 to 240.
