Is there away to use dual bladed saber or dual sabers in sp. also how do you get them both to work in mp. You know one at a time.
There is no source for the SP code & assembly code is too much of a pain to work with, so there will more than likely never be dual bladed sabers or dual sabers in SP; Not for JK2 anyways. They will both be in there with JK3.
As for getting them to show up in MP, go in to the in-game menus, Controls -> Other; You can bind either one there. The grapple & jetpack are in the Controls -> Movement as well.
