Converting .btx for DRAE:UDG PC

[quasqade]

It looks like Danganronpa Another Episode: Ultra Despair Girls for PC uses slightly modified SHTXFS format for sprites with headers SHTXFs or SHTXFf. Sprites with SHTXFs can be converted just like like SHTXFS. Sprites with SHTXFf header are without palette and use BGRA instead of RGBA.
Another .btx format are compressed .dds textures that can be decompressed, resulting in DDS1DDS header. If leading DDS1 is removed so file starts with DDS, it can be opened as a .dds texture.

@xdanieldzd Sorry to bother you, but would you please look at this?
Your code work just fine with the Vita files, however with the PC ones not, the palette is wrong.
If you add this line to your code:

imageBinary.InputPaletteFormat = PixelDataFormat.FormatArgb8888;

it would work only with the PC version, however I have not idea about how to automatically distinguish the Vita files from the PC files.

I attached some examples from Vita and PC.

It's good that someone smarter than me figured what needs to be done, I'd really appreciate if you could fix it, @xdanieldzd
