This section has a bunch of textures
| Offset | Type | Description |
|---|---|---|
| 0x0 | uint16 | Number of textures |
| 0x2 | uint16 | Number of CLUTs (color lookup tables) |
Immediately following the header (at offset 0x4 from the start of the file) is an array of texture descriptors.
| Offset | Type | Description |
|---|---|---|
| 0x0 | uint32 | Image Data Pointer (relative to header) |
| 0x4 | uint32 | Palette Data Pointer (relative to header) (might be null) |
| 0x8 | uint16 | Image height |
| 0xa | uint16 | Image width |
| 0xc | bool | Edge LOD enable (?) |
| 0xd | uint8 | Min LOD (?) |
| 0xe | uint8 | Max LOD (?) |
| 0xf | bool | Unpacked? |
| 0x10 | byte[7] | Unknown/padding |
| 0x17 | uint8 | Image format |
| 0x18 | uint16 | Palette entry count |
| 0x1a | uint8 | Palette format |
| 0x1b | byte[5] | Unknown/padding |
This is probably a version of the TEX0 format. I extract the textures by shuffling around the data to create a valid TPL file and then converting it to a png with wimgt. I don't know where the LODBias, wrapS, wrapT, minFilter, and magFilter are in the header, so I assume they're 0.
