Cave unit definition file
In Pikmin 2, each sublevel points to a cave unit definition file. These files can be found in /user/Mukki/mapunits/units, and contain a list of units that the game is allowed to use to create the cave with. This file just tells the generator how each cave unit attaches with one another. In other words, this file specifies all the rooms to spawn in a sublevel, depending on that sublevel's room count ({f005}).
Header
After a decorated set of comments that say units definition file comes a line containing the number of units defined in this file. This line is commented with number of units. Each unit's data is defined inside its own block, and conveniently has a comment before it that mentions its name.
Unit
| Line | Example | Description | Comment |
|---|---|---|---|

| 3 | 7 6 |
Width (7) and length (6) of the unit that's spawning (line 3); defines how many cave grid cells this unit | dX/dZ ; cell size

| 4 | 1 |
Room type: 0=dead end, 1=room, 2=hallway | room type
|
| 5 | 0 1 |
The unit's "room" flags. Judging by the name, and how most of the "room" type units have it set to 1, it's presumed to help count the room units as... well, rooms and not hallways or dead ends. Changing it to anything other than 1, or 0 for the non-room units, doesn't seem to do anything though. | room Flags
