Revenge of the Jedi: Game 2

Howdy folks,

There are 2 "Revenge of the Jedi" prototype boxes:

Game one we know about:

Game two has a pic here, and sounds like it was never finished:

Does anyone know what the back of the second box looks like?

Is there a fake mock-up, or any gameplay listed?  Or, is it blank?

Thanks!
