Invisible efficiency for Game Boy: when the screen isn't changing, Zero stops redrawing it and lets the CPU idle.
- Present-skip on GB, GBC, GBA: identical frames aren't re-sent to the display. Automatic; other systems unchanged.
- Up to ~45% less CPU: on a fully static screen, ~20-32% in real play. Motion is never affected, so it never costs anything.
