 ====Actor Section====
-This section is a FixedHash which holds actor data. Each entry corresponds to one actor. Every entry points to non-node data, usually blocks of 0x90 bytes, but sometimes longer. The names section is empty. The data block for each actor is formatted as follows. Some properties are related to measurements along certain axes; since this is a top-down game we will call the vertical axis Z (i.e. the axis toward the camera), and X and Y will be as normal for a 2D game.
+This section is a FixedHash which holds actor data. Each entry corresponds to one actor. Every entry points to non-node data, a block with a minimum size of 0x90 bytes, but can be longer. The names section is empty. The data block for each actor is formatted as follows. Some properties are related to measurements along the three axes; since Link's Awakening is a top-down game we will call the vertical axis Z (i.e. the axis perpendicular to the plane of the floor), and X and Y will be as normal for a 2D game.
