Certain [[major glitch]]es in ALttP, if performed incorrectly, are described as freezing your game for "up to 18 minutes".

Some events in the game depend on timers or similar counters that count down once per frame until they reach a target value. When these events occur as intended, the counter will be initialized so that it takes an appropriately small number of frames.
