BRRES Files are used to make objects. They contain models, textures and animations

Known editors:

Format

BRRES Files are similar to SZS Files. They contain multiple sections, sometimes refered to as files. The format has been used in many games by Nintendo. This article describes Mario Kart Wii BRRES files.

Header

The file begins with the header. It is a 0x10 structure. It is as follows:

Offset Type Description
0x00 char[4] 'BRES' in ASCII; File identifier.
0x04 short Byte order mark. 0xFEFF is the big endian byte order, 0xFFFE is little endian.
0x06 short Padding.
0x08 int Length of the file in bytes.
0x0C short Offset to root section relative to start. (0x0010)
0x0E short Number of sections (including root).

Sections

Root

The root section of the brres file contains all pointers to files and filenames The header of the root is 0x8 in length.

Offset Type Description
0x00 char[4] 'root' in ASCII
0x04 int Length of section in bytes.

This header is then followed by a BRRES Index Group. The entries in this group are the folders of this brres file, and point to more BRRES Index Groups within the root section. These then point to the actual sections of the BRRES file.

Others

Other BRRES sections tend to be within specific folders, as set out by the root section. The identifiers of these sections, as well as the normal folder and a description are listed below. BRRES Files contain only a few file formats, they are:

Identifier Folder Description
MDL0 3DModels(NW4R) Model files.
TEX0 Textures(NW4R) Texture files.
SRT0 AnmTexSrt(NW4R) Texture movement animations.
CHR0 AnmChr(NW4R) Model movement animations.
PAT0 AnmTexPat(NW4R) Texture swapping animations.
CLR0 AnmClr(NW4R) Colour changing animations.
Not seen Palettes(NW4R) Known to exist from main.dol
Not seen AnmVis(NW4R) Known to exist from main.dol
Not seen AnmShp(NW4R) Known to exist from main.dol
Not seen AnmScn(NW4R) Known to exist from main.dol
Not seen LightSet(NW4R) Known to exist from main.dol
Not seen AmbLights(NW4R) Known to exist from main.dol
Not seen Lights(NW4R) Known to exist from main.dol
Not seen Fogs(NW4R) Known to exist from main.dol
Not seen Cameras(NW4R) Known to exist from main.dol

String Table

At the end of the BRRES file is a string table. This is a series of 4-byte length prefixed strings, padded to start at four byte offsets. Various sections point to this table, which is how all text in BRRES files is stored.
