    ive spent some time figuring out how the town map works in platinum. this is not about changing the graphics but instead the location of blocks and cities on the map. Blocks are the tiles on the map that are "active", meaning that they display the maps headers name bellow the map, determine the guidemap data, and make them selectableto fly to.

    this data is for platinum. the overlay and offsets are probably different in diamond and pearl. everything else should otherwise be the same.

    Anyways:
    Spoiler:
     
    I should note that most of the Town Map data relies heavily on file 0 of map_matrix.narc, since most of the data is dependent on it (except for indoor locations or maps that use a different map matrix file in the archive). So most of the Town Map changes can be made though modifying file 0 in map_matrix.narc
     
    for anybody wants to edit the rcsn tilemaps, the formats are the exact same as gba tilemaps. You can remove the header from the exported file (the first 24 HEX bytes) and load into any gba tilemap editor. I've tried it with Tilemap Creator and NTME.
