it's very funny to me that three zelda games share a glitch called Back In Time that's completely useless in two of them and breaks the third wide open due to just a slight change in how the main menu screen works in that game

it was discovered in the first two before the third came out, so the one game that Back In Time is useful in came out after the discovery of Back In Time

however, the first two games have two methods for performing Back In Time and the third only has one, which is the less convenient one to set up

so for a while, people thought it didn't exist in the newer game, because the method they tried for setting it up didn't work
