0x8C int16 80 00 128 width of the image in pixel
0x8E int16 80 00 128 height of the image in pixel
0x90 int32 01 00 00 00 1 texture format RGB555; used texture formats:
0 - ARGB4444, 16 bits/pixel, 4 bits per channel, alpha channel present (GL_RGBA4 OpenGL texture format)
1 - RGB555, 16 bits/pixel, 5 bits per channel, no alpha channel (GL_RGB5 OpenGL texture format)
2 - ARGB5551, 16 bits/pixel, 5 bits per color channel, 1 bit alpha channel (GL_RGB5_A1 OpenGL texture format)
8 - RGB888, 32 bits/pixel, 8 bits per color channel, no alpha channel (GL_RGB OpenGL texture format)
9 - S3TC/DXT1, compressed 4 times (GL_COMPRESSED_RGB_S3TC_DXT1_EXT OpenGL texture format)
0x94 link 00 00 00 00 unused link to a TXAN file; only used if the texture is the first pic of an texture animation
0x98 link 00 00 00 00 unused link to a TXMP file; only used in connection with shade vertex effects
0x9C offset 20 00 00 00 00 00 00 20 at this position starts the texture part in the raw file (PC only)
0xA0 offset 00 00 00 00 unused at this position starts the texture part in the sep file (Mac and PC demo only)
0xA4 char[28] AD DE dead unused


Below you can see the pictures for this example. The first picture shows how it's stored in Oni, the second how you see it in the game.
