Sonic the Hedgehog Games Model Ripping

[Yarcaz]

Here are some models that I have ripped from "Sonic Chronicles".
                           

BTW, in "Sonic Chronicles" when I try to open up or unpack/extract/view the files for "armdiln_aa.nsbtx.small" I t doesn't unpack via command prompt with the "unnsbtx" from "xoreos-tools" and if I am using "MKDS Course Editor" which worked with the other ".nsbtx.small" files for this specific file, it just crashes that window. So I have the model of the "Armadillo" from "Sonic Chronicles" but I need help to get its texture. Here is a screenshot of the command prompt error.
