==== Tile Modifiers ====
The modifier "tiles" (0x76, 0x77, 0x78) affect the tile specification that they carry in their additional data. The meaning of the modifier value depends on the type of tile they affect.
The modifier "tiles" (0x76, 0x77, 0x78) affect the tile specification that they carry in their additional data. The meaning of the modifier value depends on the type of tile they affect.


The size of the modifier is irrelevant, and modifiers default to zero.  That is, if a tile is expecting a 16-bit modifier but the high byte is zero, an 8-bit modifier works as well.  If a tile is expecting an 8-bit modifier which is zero, the modifier may be omitted entirely.
==== Wire Modifier ====
 
This is an 8-bit modifier that affects floors, metal walls, on/off switches, transformers, and blue/red fans (possibly more?). It adds wires to the tile it affects. Any number of these bits can be combined:

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.

The upper nybble is the tile's initial "entered" direction.  When an actor starts the level already on top of this tile, it's treated as though it entered by moving in this direction.  (If there are no tracks corresponding to that direction, the actor will be unable to move.)
