Map unit
This article is a stub. You can help ZeldaMods (Breath of the Wild) by expanding it. Complete the contents section, the link system, mention static vs dynamic (and possibly other things) (For a list of non-stub pages, see Project:Pages.) |

Objs
Array of object structures. Must be sorted by HashId[1] because the placement subsystem performs binary searches on the object array in various cases[2].
Rails
Array of rail structures. Can only appear in group 0 maps (Static); this section is completely ignored for non-static map units.
Link system
Map objects can be linked to other objects (up to 255 in a single generation group[3]). These links allow implementing custom logic and callbacks (for example, DeadUp signals the destination object when the source object dies).

File formats
Map unit binary
In Breath of the Wild, map units are stored in a binary format and given the mubin (Map Unit Binary) file extension. All map object IDs are replaced with CRC32 hashes as a space optimisation. BYML is used as the serialisation format.
Source map unit
Source map units have muunt[4] as their file extension and use strings for map object IDs such as F-5_challenge.muunt/obj760 instead of CRC32 hashes of the IDs in map unit binaries.
- ↑ Technically, sorting is only required for Dynamic (non-group 0) map units. However, not sorting causes the game to fall back to a slower linear search.

- ↑ The executable has remnants of functions that can load map units with the following path:
