I used PS Picture and ISO Buster and managed to somehow extract Track1.tao from Valkyrie.bin, but that's not saying much as they're virtually the same filesize as before (I put them in a separate folder). I used PSicture and managed to get a couple files: A couple Ground Map skins (to overlay the world map), the Valkyrie Profile Save Game Block logo (with 3 frames of her blinking), A 3D Box Platform (from one of the stages), Mountain Map Skin overlays for the world map, and a series of chunks of the big and small versions of the world map.
That's about it. Do I need to reverse engineer this game? I know people have managed to rip the PSF files from it.
