You will also need a picture of Mario, or the video game sprite you wish to create. I got the image from the good ol' internet, and "Zoomed In" in an image editing program. I selected "show grid" and took a screen shot which I cropped and printed. This was my guide.
Since I was using a black and white printer, it was hard to distinguish certain parts, so I recolored some pixels to improve contrast.
