The .MAPA file format defines the minimap models used in the Metroid Prime series. MAPA or MAP Area consists of several sections: The header, Point Of Interest entries, Vertices, Primitive Headers, and the primitives.


Morphball wirerender.png This file format needs more research
A few things are unknown in the header and POI Entries


Format

Header

The header is very straight forward, and has some minor differences depending on version, the unknown values don't seem to do anything, however not much research has been put into them.


Type Description MP1 MP2 MP3
u32 Magic; Always 0xDEADD00D ✔ ✔ ✔
u32 Version; See below ✔ ✔ ✔
u32 Type; unknown function in MP1/3, specifies whether the area appears on the Light (0) or Dark (1) map in MP2 ✔ ✔ ✔
u32 Visibility Mode;
  1. Always Visible
  2. Visible on Visit or Map Station (most MP1 areas)
  3. Visible on Visit only (latter areas of Ruins and Phendrana)
  4. Never Visible
 ✔ ✔ ✔
CAABox Bounding Box ✔ ✔ ✔
u32 Unknown ✖ ✔ ✔
u32 Unknown ✖ ✔ ✔
u32 Unknown ✖ ✔ ✔
u32 Unknown ✖ ✖ ✔
u32 POI Count ✔ ✔ ✔
u32 Vertex Count ✔ ✔ ✔
u32 Primitive Count ✔ ✔ ✔

Version

The version value listed above can have the following values:

Game Value
Metroid Prime 1 2
Metroid Prime 2: Echoes 3
Metroid Prime 3: Corruption 5

Point of Interest

A Point of Interest in the Metroid Prime series can include: Mission Objectives, Elevators, Doors, Map Stations, and Missile Stations. Each Point of Interest entry consists of the following struct:

Type Description MP1 & MP2 MP3
u32 Unknown ✖ ✔
u32 Type; See table below for MP1 types ✔ ✔
u32 Visibility Mode;
  1. Always Visible
  2. Visible on Map Station or Area Visit
  3. Visible on Door Visit
  4. Never Visible
  5. Visible on Map Station or Area Visit
 ✔ ✔
u32 Editor ID; Same ID format as SCLY, indicates associated world object ✔ ✖
CVector4f Unknown ✖ ✔
u32 Padding; always -1 ✔ ✔
CTransform4f Tranform Matrix The Point of Interest's position in world space. ✔ ✔
u32 * 4 Padding; four values of -1 ✔ ✔

MP1 Types

27 Down Arrow Yellow (Maintenance Tunnel)

30 Up Arrow Green (Elite Control Access)
31 Down Arrow Red (Elevator B)
32 Up Arrow Red (Fungal Hall Access)
33 Elevator
34 Save Station
37 Missile Station

Vertices

Vertices are a simple array of CVector3f. Geometry in MAPAs is, almost always, centered around the origin (0, 0, 0) and are simplified, full sized, versions of the map they replicate. Each vertex is referenced at least twice: once for the primitive, once for the line border.

Primitive Headers

The Primitive headers are extremely simple, they merely have a bounding box followed by the primitive table start and end point, relative to the end of the current primitive header. In other words: read in the header, seek to the start of the table from the current position, then read the primitives tables.

Type Description
CVector3f Normal
CVector3f Center of Mass
u32 Primitive Table Start; relative to the end of the header
u32 Border Table Start; relative to the end of the header

Primitive Table

The Primitive is also fairly simple, each one consists of two parts: The GX Primitive list, and the Border list.

Type Description
u32 Primitive Count (PC)
Primitive * PC Primitives
u32 Border Count (BC)
Border * (BC) Borders

Primitive

A primitive in a MAPA is a simple 4 byte aligned list of indices into the vertex list, starting with the GX Primitive type, a count, then an array of indices, each index taking up one byte.

Border

A border in a MAPA is a simple count followed by a 4 byte aligned list indices into the vertex list, each index taking up one byte. A border is simply drawn using GX_LINESTRIP.
