 #### LIDAR_GET_PATH
 Generates a path as a sequence of words, each representing a direction. The generated path starts at the address specified in the C register but varies in length. It is terminated with the word `0xAAAA`, which represents the end of the path. If a path could not be generated, then the memory at address specified in the C register is set to `0xFFFF` (Note: The path terminator is not written for invalid paths).

 #### LIDAR_GET_MAP
-Generates a map of the current world as a sequence of 256 words, each word representing a tile. The starting address of the generated map must be specified with the X register. The LiDAR reads the tiles west to east, north to south: (0,0) (1,0) (2,0) ... (15,0) (0,1) (1,1) ... The first 16 words will be the north-most row from west to east, the next 16 words will be the next row down (south), etc. Ending with the south-east most tile.
+Generates a map of the current world as a sequence of words, each word representing a tile. The starting address of the generated map must be specified with the X register. The exact size depends on the world you are in. The LiDAR reads the tiles west to east, north to south: (0,0) (1,0) (2,0) ... (world-size-x -1,0) (0,1) (1,1) ... The first world-size-X words will be the north-most row from west to east, the next world-size-X words will be the next row down (south), etc. Ending with the south-east most tile.
 
 Each tile is encoded as a bit field with the following format `OOOOOOOO TTTTTTTB`. Starting from the left, the first byte specifies the object ID on this tile, the next 7 bits specifies the tile ID. The rightmost bit indicates if the tile is `blocked` or not.
