A final word on this particular, ladies and gentleman (and no, Xenovant and Pstemarie ain't ladies): Turning my override models into binaries fooked (marvelous word, Jez!) several creatures and a complete override tileset, so I would recommend turning overriding models ONLY in a one by one basis, cause this way you can check the results of the compression on each model, individually, rather than changing thousand of files and later fishing out the ones that don't work right anymore. This should go without saying, but you should also keep an original ASCII version copy of the model, so you don't commit suicide if the binary version kills it!
