TEX Texture Data Format for PC by Mirex (Edits by Aali)
FF7 PC texture consists of header, an optional palette and bitmap data. Usually data are stored like palletized picture, with bitmap pixels referencing to palette. Color 0 (in palette its usually black) is usually used as transparent color.
Pixel values of 0 may or may not be transparent, depending on the color key status, more on that later. This also applies to non-paletted formats.
When bit depth is 16 then data are stored as packed RGB in style RGB555, which means 5 bits per color in one 2 byte entry. I'm not sure if it is used in FF7 at all, its probably used in FF8.
The tex format is actually very flexible and can take almost any non-paletted format as long as you describe it properly in the header.

Number of palettes * 1 bytes. | |
Color keying: If the color key flag is zero, no color keying is performed and the color key array is ignored. Otherwise, the current palette index is used to retrieve a single byte from the color key array, this is the new color key flag, zero means don't do color keying. If there is no color key array (and the color key flag is not zero), you should always color key.
Reference alpha: Only applies to paletted images, if the alpha value sampled from the palette is 0xFE, this value should be replaced with the reference alpha.
