-====== Warp Triggers ======
-===== Overview =====
-When the player steps in a specific coordinate in the map, he is transported in a new map with new coordinates.
-===== Offsets =====
-^  Description          ^  Value    ^
-| Base offset (SNES)    |  $DFBB00  |
-| Block size            |  $02      |
-| Number of blocks      |  $01A0    |
-| Total size            |  $0340    |
-The structure is a sequence of two-byte pointers. The index of the pointer is relative to the map number.
-The actual offset of the appointed data is the pointer value plus the base offset.
-The game system checks the actual pointer and the next pointer to determinate the amount of data to read. It can include multiple data blocks.
-===== Data =====
-^  Offset   ^  Mask     ^ Description               ^
-|  $00      |  $FF      | x position, actual map    |
-|  $01      |  $FF      | y position, actual map    |
-|  $02      |  $FF      | new map, low byte         |
-|  $03      |  $01      | new map, high bit         |
-|  :::      |  $02      | ?                         |
-|  :::      |  $04      | ?                         |
-|  :::      |  $08      | display location name     |
-|  :::      |  $30      | direction facing          |
-|  :::      |  $40      | ?                         |
-|  :::      |  $80      | ?                         |
-|  $04      |  $FF      | x position, new map       |
-|  $05      |  $FF      | y position, new map       |
-===== Notes =====
-The coordinates of the new map must be valid. Otherwise, the player can be stuck in a no-walkable tile and unable to move. Also, the warp system won't work correctly if the new coordinates bypass the new map maximum coordinates.
