I found that chara.dds.phyre and enemy.phyre are .gxt image. But you will need a tool that can extract only the necessary data by batch process, and also flip the image (I think all of the images will be like this). Maybe someone in this site with a bit knowledge of programming can help you (Sorry, I don't have any knowledge of it). This is what I got by getting the data of that .dds(the little guy) and from enemy.phyre (the yellow thing and the shadow):
Also, I figured out that .dae.phyre doesn't have any related to sprites. Maybe this are for 3D models or another thing.
