"T" stands for "Textures"
The TPSX section holds texture data. As it is the first section of every WAD, it also contains the level's title.

|---|---|---|---|
| 0x0 | 0x4 | Section's name | Value: 58 53 50 54 ("XSPT") |
| 0x4 | 0x4 | Section's size / Offset to the next section | |
| 0x8 | DEPENDS | TPSX header | In the dummy WADs of Croc 2 Demo, there is no TPSX header |
| +0x0 | DEPENDS | Textures file |

On your hex editor, the bits are in this order:
| 07 06 05 04 03 02 01 00 | 15 14 13 12 11 10 09 08 | 23 22 21 20 19 18 17 16 | etc.
| Bit | Usage | Notes |
|---|---|---|
| 0 | UNKNOWN | |
| 1 | Title & demo mode data | If not set, there is no TPSX header, the data starts immediately after these flags. If set, there can be title(s) and 800 bytes are added after the title(s) to make room for Demo mode data |
| 2 | UNKNOWN | Set on all levels I reversed |
| 3 | Presence of legacy textures | If set, 5 textures (0xC00 long each, 0x3C00 in total) appear between the texture descriptors and the raw texture data |
| 4 | Multiple titles | If set, multiple titles are defined (usually one per language). The first unsigned long is then the number of titles, followed by 0x30-long titles. |
| 5-31 | UNKNOWN / ∅ Empty |
