[Guide] Ripping models from Sketchfab

I managed to get it working, with a few differences to how tho.
installed python 2.6 x64 version
added the environmental variables
i clear the chrome cache, run chromecacheview and load then refresh the SF model
save selected items 1 at a time from the viewer, file.osgjs.gz.txt model_file_wireframe.bin.gz.txt and model_file.bin.gz.txt into a directory of my choosing
i then drop blend249.blend onto blender version 2.49b
as soon as it loads, alt+p and select the file.osgjs.gz.txt, check the console window and see it is making the mesh.
using chromecacheview, the gz's save uncorrupted and at the correct size. no need to download them through a browser or copy and paste into notepad.
hope that helps someone else.
