- Added dungeon_map.cc to the build configuration for improved organization. - Refactored namespace usage to yaze::zelda3 for better clarity. - Updated LoadDungeonMaps and SaveDungeonMaps functions to use kNumRooms constant for room handling. - Improved error handling in LoadDungeonMapGfxFromBinary function and added comments for better documentation.
