Yes, that's true. However, the first sprite of the picture he posted CAN follow limitations. He just have to use layers, like you said.Shiru wrote: You can increase number of colors by using few palettes for different 8x8 parts of the sprite, however, it'll reduce number of colors for other sprite objects on the screen. The picture you posted is not follow these limitations.
True, it will decrease number of colors for other objects, BUT megaman have 6 colors(3 for body and 3 for face), so if you plan it carefully, you can have 4 colors for hero. Especially, if you plan to have a common enemy with legs color or shirt's.
