Program Modifiers[]
Program Modifiers are key items that allow you to rotate Navi Customizer programs, using the L or R buttons in the Navi Customizer map space. This lets you place programs in a manner that allows more space within the map. There is one for each color programs come in, giving you a total of 6.
