Edit: Not how but Why?
Why do 2D games have the main character locked in the middle of the screen when the character starts to move to the middle of the game screen?
Mario NES, Kirby GBA, Megaman NES, Ghost and Goblins NES all do this.
There are exceptions where the main character to "break out of the lock". This happens when Kirby needs to go to a door or when megaman needs to climb a ladder
