Introduction

Read BREFF and BREFT (File Format) for an introduction.

File Format

A BREFT sub file starts with a header of 32 bytes followed by the texture data. The Sub File Item explained here points to this header. The size of the sub file item only counts the size of the texture data.

Offset Size Type Description
0x00 0x04 UInt32 Unknown. Null for all 1200 BREFT files in Mario Kart Wii.
0x04 0x02 UInt16 Width of texture in pixel (values in the range 0x8-0x100).
0x06 0x02 UInt16 Height of texture in pixel (values in the range 0x10-0x100).
0x08 0x04 UInt32 N = size of texture data.
0x0C 0x01 Byte Image format of texture (see below for details).

Found in MKW: 7* 0x00, 675* 0x01, 462* 0x03, 5* 0x04, 25* 0x05, 2* 0x06, 24* 0x0E

0x0D 0x03 Byte[3] Unknown. Null for all 1200 BREFT files in MKW. Perhaps 0x0C is a mistake and a little endian 32-bit number.
0x10 0x04 UInt32 Unknown. Null for all 1200 BREFT files in MKW.
0x14 0x01 Byte Null or the total number of images (main image + mipmaps). In MKW only 2 files have the value of 2 here (factory_course.szs and _d variant, effect/Alarm/rk_alarm.breft, alarmMip). For all other files the value is 0.
0x15 0x03 Byte[3] Unknown. Null for all 1200 BREFT files in MKW. Perhaps 0x14 is a mistake and a little endian 32-bit number.
0x18 0x04 UInt32 Unknown. Null for all 1200 BREFT files in MKW.
0x1C 0x04 UInt32 Unknown. Null for all 1200 BREFT files in MKW.
0x20 N UInt32 Texture data.
0x20 + N End of sub file
