The files you linked use the 0x03 compression. I've tried several routines and none even come close.
Here is what is looks likes without.

Edit:
Wait... I think I got it.
So now I understand compression 0x01 and 0x03 and can actually build the image.
That leaves 0x02 and 0x04 and hopefully 0x05 doesn't exist
