That guide is pre-ISBoxer and not for the faint of heart.

I of course agree with the others, you can probably just set up a Repeater Profile through ISBoxer and be done with it, but I believe in order to use Keyclone you will need to manually select the game windows, since they are renamed by Inner Space.
