The idea of making this program came after a chat with Yuski the Dog. He, like me, was complaining about the lack of a collision viewer for Sonic games. At the first time, I really hadn't any idea how I could make such program. After finding out that a bunch of TextBoxes was a stupid idea, I worked hard on trying to get the PictureBox to do something. Fortunatelly, I learned how to use the PaintPicture method, and then the dream of the collision viewer was coming true.
