The MAPW format defines the map for a world, which is basically just a list of MAPA files.


MAPW is essentially just an array of MAPA IDs. There's always one MAPA per area. The MAPW format has never been updated; every Prime game uses the same version of the format, version 1. The only difference is that Prime 1/2 have 32-bit file IDs, while Prime 3 has 64-bit ones.
