One more thing, it's also possible to alter the sprites themselves with Microsoft Paint. Gives the characters more emotions. For example, during my Sonic Adventure 2 adaptation, Sonic had a suprised look when seeing Shadow-chan, but then he had a perverted look on his face when he relized that she was a girl. (the perverted look was an altered suprised look)
