Data Structure
| Data Offset | Size | Description |
|---|---|---|
| 0x00 | Uint8 | Width of Global Map |
| 0x01 | Uint8 | Height of Global Map |
| 0x04 | Uint8 | Number of Characters of Map Prefix |
| 0x05 | Char* | Map Prefix Name |
| Next | UInt16** | Data |
* Length determined by 0x04
** Length of data is Height X Width
Data In Use
Let Height = 3, Width = 3, Data = ABCDEFGHI, Map Prefix = ExMap (so prefix length is 5)
[[A B C] [D E F] [G H I]]
This illustrates that the value at B goes with the map named ExMap00_01c because B is (0,1) in the above matrix. The map names are declared within the proper land_data[_release] files.
The value of B is the map value, that is, the value of the index of the map (where 411 is Twinleaf Town in DPPt and 60 is New Bark Town in HGSS).
