Next I displayed the backround with BGLOAD 0,BG. Then I made BGX and BGY to track the coordinates of the background. Inside the loop, I get the direction of the circle pad and put the x position in SX and the y position in SY. If the circle pad is to the right then I move the backround right and if it's to the left I move it left. Then I move the backround on the screen by using BGOFS,
