This is an 8-bit modifier that affects an inverter gate by replacing it with another gate. Modifiers outside of the ranges specified below will produce [[voodoo tile]]s.
Most logic gates have 4 assigned values instead of just 1; unless otherwise specified below, the face direction of the logic gate is determined by its index, stored in the order: North, East, South, West.
