I got something but it looks weird.. I read that PS Vita textures are GXT but I don't know much about that format. Here is my result using "Image Heat"
I also used ScarletConvert and GXTConvert but those tools don't work with these textures...

Those BSTEX files are just containers for PS Vita GXT image files. Here's a file format https://rewiki.miraheze.org/wiki/GXT_Image
If you remove manually 32 bytes from BSTEX file in hex editor and change file extension from BSTEX to GXT, you will be able to open them in Scarlet. Unfortunately PVRTII4BPP is not supported by Scarlet, so you will be able to convert only BC/DXT textures this way.

While doing research on your samples, I discovered that ImageHeat had a bug while unswizzling 4bpp PS Vita textures.
I fixed this bug in v0.26.3, so you can use this version (or newer) to properly view PVRTII4BPP textures:

Thank you so much for the reply and for looking into the samples.

 

However, I’m not very familiar with the programs you mentioned. Would you mind sharing a download link for the textures you were able to extract?
