8C63: The handler for a piece of food
Sprites $50 to $57 are food, and ACTOR_HANDLERS sends all eight of them here. Every frame it asks whether the player is standing on it; if not, it just draws itself and that is the whole of its behaviour.
Eating is worth $40 -- a quarter of the bar -- and the total is held at $F0 rather than being allowed to wrap, so arriving at a roast with almost full health wastes most of it. The two branches before the cap catch the carry as well as the compare, because $5E28 plus $40 can pass $FF.
