Unknown Image format from mobile games

[Shine]

I got these textures from 2 different game. They look like DXT1 which compression ratio are 1:8.
But I can't get the correct images. I wonder if this is a common format of mobile texture?

Phantom Soul has 68 bytes header

Absolute field has 16 bytes header

Phantom Soul uses KTX format
Absolute field uses PKM format

Try PicoPixel, it should help.

Looks like texgenpack supports them too, but it crashes on pkm files
You may need manually change file extensions to make texture acceptable to texgenpack.

Ericsson texture de/compression tool supports both texture types, but you still do need to change file extensions

Thanks NullRd and Acewell.
Mali Texture Compression Tool seems to be the best.
etcpack is handy but some ktx cannot be converted!
