Yeah that's how the map array works, whenever you move, it will update the sides of the screen by placing new BG tiles from the array, overwriting any previous BG there, allowing you to have maps larger than 64x64, also I made it so it will only update the side(s) that need it, so for example it wouldn't update above the screen if you are only moving right, I did that to help performance and reduce any lag. Oh and btw, the reason I'm using the expert version of BGPUT is to save memory and also it's probably faster too.
