Help with Texturing

[AllenSword]

Ok. After I rip the models, the textures are usually off for example somebody will have four eyes instead of two or something like that. I'm going to post some pics of the problem when I have free time, the game I'm trying to rip from is Pokemon Colloseum. Supposedly there is a program that can extract the models from pokemon xd, which is similar, but I never found it. I tried to take the .fsys files and convert them, and when I do they have the format of .fdat or .unpacked. I don't know how to open them which is why I rip models with 3d ripper dx.
