The NES, although being an awesome console (especially considering its age), is not without its limitations. For example, the NES can draw up to 64 sprites on screen. A sprite is an 8×8 pixel image that can move freely on screen. So for instance when your main character is a 16×16 pixel character, it will use 4 of the 64 available sprites. To make matters worse, whenever there are more than 8 sprites on a horizontal scanline, additional sprites on that line won’t be drawn. Here are two code modifications which can help you overcome this limitation.
