Sonic the Hedgehog Games Model Ripping

[tyler]

is there a less destructive way to rip generations and unleashed models?
libgens modelfbx.exe programs dont work entirely* for unleashed and leaves out extra uv maps
and sonic glvl dae converter only seems to work for unleashed and messes up normals AND leaves out vertex colors

(* it works for unleashed models but not with rigging)
