Need help ripping PS3 & Xbox 360 .tga.ckd Sprites

Hi, I've been trying to learn how to rip sprites from all versions of Rayman Legends (and Origins) by myself. So far I've been able to rip from PC, Wii U, and Vita versions but I can't figure out how to convert .tga.ckd files from the PS3 and Xbox 360 versions. I've tried converting them to DDS but when I do add the DDS header on a HEX editor and open them, they don't look very well, might I say. I've noticed through research that they are apparently compressed, and can be converted to dds, but are not dds files, no further explanation


Here's a sample if anyone wants to see them:

And yes, I know that the ones I am trying to rip have already been done by RTB, but I am trying to figure how they were ripped. That and I also need unaltered versions of those sprites anyway. If anyone has any suggestions, like tools or conversion methods please let me know.
