The purpose of this tutorial is to show what you can do with multicolored tiles offered by MIDRES library, and what happens when this feature is used by hardware that does not support this type of tiling. It's all about making a simple animation of a moving ghost. The ghost resembles that one of the PAC-MAN game in its various incarnations, and it will be moved horizontally from one side of the screen to the other, using the PAC-MAN effect, of course!
For those computers that have native support for multicolor tiles, the ghost will appear in all its coloring; in other cases, it will appear with a minimum of dithering. However, it should be noted that the higher resolution tiles remains available even if, obviously, with only two colors (monochrome).
