# Europa PS2 Texture File (.tex)
|
||
|
|
|
||
|
|
On PS2, the Europa engine uses a homebrew texture format, known as "YATF" or, ~~probably~~ definitely **Y**et **A**nother **T**exture **F**ormat. Glad to know this team had some humour to them.

| 1 | Introduced in Starfighter. |
|
||
|
|
| 2 | Introduced in Jedi Starfighter. Breaks the FourCC magic and adds a 4bpp mode while jumbling all the other modes. |

# Header
|
||
|
|
|
||
|
|
The .tex file header is one of the few filetypes in Europa which uses a proper FourCC magic. However this becomes rapidly annoying as you'll see later.
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
struct yatfHeader {
|
||
|
|
uint32_t magic;
|
||
|
|
uint16_t version;
|
||
|
|
Format format; // Version-specific
|
||
|
|
uint8_t unknown; // ?
|
||
|
|
uint32_t unknownZeroed; // Zeroed on all files
|
||
|
|
|
||
|
|
uint32_t width;
|
||
|
|
uint32_t height;
|
||
|
|
};
|
||
|
|
```
|
||
|
|
|
||
|
|
### Version 1
|
||
|
|
|
||
|
|
Version 1 writes its magic (in LE) as `FTAY`.
|
||
|
|
|
||
|
|
Version 1 formats are:
|
||
|
|
|
||
|
|
| Int | Format type |
|
||
|
|
| --- | ---------------------- |
|
||
|
|
| 0 | 8bpp CLUT (256 colors) |
|
||
|
|
| 2 | 24bpp direct color |
|
||
|
|
| 3 | 32bpp RGBA8888 |
|
||
|
|
|
||
|
|
### Version 2
|
||
|
|
|
||
|
|
Version 2 writes its magic (in LE) as `YATF`. I have no clue why they did this because it pretty much means they broke the format anyways.
|
||
|
|
|
||
|
|
Version 2 formats are:
|
||
|
|
|
||
|
|
| Int | Format type |
|
||
|
|
| --- | ---------------------- |
|
||
|
|
| 1 | 8bpp CLUT (256 colors) |
|
||
|
|
| 3 | 24bpp direct color |
|
||
|
|
| 4 | 32bpp RGBA8888 |
|
||
|
|
| 5 | 4bpp CLUT (16 colors) |
|
