what is this and what is the purpose of this what extras does it have that a chip cannot do?

its jsut an extra program that allows you to see the XBOX from your pc, upload files, run files from the Harddrive, emulators etc..wicked program every chipped xbox should have it! the onyl tihng it has that the modchips at the moment dont have is the ability to replace the hard drive with a much bigger one, so u can copy all your games to it and run them form there!
hope this helps
