RFL_Res.dat (File Format)
RFL_Res.dat is the only sub file from /contents/RFLRes01.arc, and present in many Wii games that use Miis. It contains all Mii head components, such as face, hair, beard and nose models, as well as the textures used for the eyes and eyebrows between others. The name suggests it was generated by the Revolution SDK's Face Library.
File Format
The file is big endian, and structured in eighteen sections, each one corresponding to a group. It starts headerless, with a tree structure directly.
| Offset | Type | Description |
|---|---|---|
| 0x00 | UInt16 | Number of sections N. Always 0x12 = 18. |
| 0x02 | UInt16 | Unknown. The value is 0x39D = 925. |
| 0x04 | Int32[N] | Section offsets, relative to the start of the file. |
| 0x04 + (4 * N) | End of main tree, start of first section | |
Section
Each section follows a similar structure than the main tree's. There is no way to identify what each section corresponds to, except by looking at their files. Since this file is the same in all games it is used, it's assumed that they follow a common order.
| Offset | Type | Description |
|---|---|---|
| 0x00 | UInt16 | Number of files N. |
| 0x02 | UInt16 | Length of the biggest file, unknown use. |
| 0x04 | Int32[N] | File offsets, relative to the end of the offset list. |
| 0x04 + (4 * N) | Int32 | Section size. |
| 0x08 + (4 * N) | End of section, start of first file | |
File
There are two main types of files: models and textures. While textures are in BTI format, models use a standard format that does not contain material, vertex color and shader data, although it follows the Wii Graphics Code for drawing polygon indices. Each model section has a different identifier, and how much data they can handle depends of the type of model.
| Index | Identifier/Description |
|---|---|
| 1 | berd. Beard models, no UV data. |
| 2 | Texture data. Eye textures. |
| 3 | Texture data. Eyebrow textures. |
| 4 | face. Face models, with UV data and position values for the beard, hair and nose. |
| 5 | Texture data. Make up textures. |
| 6 | frhd. Forehead models, no UV data. |
| 7 | glas. Glasses model, with UV data. It only contains one model, which is used for all glasses. |
| 8 | Texture data. Glasses textures. |
| 9 | hair. Hair models, no UV data. Each one corresponds to a forehead model. |
| 10 | mask. Area with UV data where eyes, eyebrows, mouth, mole, nose lines and facial hair are drawn. Each one corresponds to a face model. |
| 11 | Texture data. Mole texture. |
| 12 | Texture data. Mouth and lip textures. |
| 13 | Texture data. Facial hair textures. |
| 14 | nose. Nose models, no UV data. |
| 15 | nsln. Nose lines, with UV data. Each one corresponds to a nose model. |
| 16 | Texture data. Nose textures. Each one corresponds to a nose line model. |
| 17 | cap_. Additional hair complements, like caps and hairbands, with UV data. Each one corresponds to a hair model. |
| 18 | Texture data. Cap textures. Each one corresponds to a cap model. |
Model format
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | Magic. |
| if magic is face | ||
| 0x04 | Float[3] | Nose XYZ position. |
| 0x10 | Float[3] | Beard XYZ position. |
| 0x1C | Float[3] | Hair XYZ position. |
| M = current position (model data offset) | ||
| M | UInt16 | Number of vertices V. |
| M + 0x02 | SByte[3][2][V] | Vertex data. The first SByte is the integer, and the second one is the decimal multiplied by 255. |
| M + 0x02 + (3 * 2 * V) | UInt16 | Number of vertex normals N. |
| M + 0x04 + (3 * 2 * V) | SByte[3][2][N] | Normal data. The first SByte is the integer, and the second one is the decimal multiplied by 255. Then, the result is multiplied by 64. |
| if model has UV data | ||
| M + 0x04 + (3 * 2 * V) + (3 * 2 * N) | UInt16 | Number of texture coordinates T. |
| M + 0x06 + (3 * 2 * V) + (3 * 2 * N) | Int16[2][T] | Texture coordinate data. Horizontal coordinates are calculated by multiplying the value by 8192, while vertical coordinates are calculated by doing the same and substracting the result from 8192. |
| P = current position | ||
| P | Byte | Number of draw commands D. |
| Polygon draw data for each draw command D, starting at P + 0x01 | ||
| 0x00 | Byte | Number of indices I. |
| 0x01 | Byte | Draw command type, as defined in the Wii Graphics Code. |
| 0x02 | Byte[3][I] or Byte[2][I] | Index data, in the order vertex index, normal index, texture coordinate index (if exists). |
