It turns out that "RIGHT_HANDED" has a number, just like TWO_FISTED. My theory is that if you were to cut RIGHT_HANDED in half and put 0.500000, and increase TWO_FISTED to 1.000000, that may be a good place to start tinkering to see if you can get the Two-Handed Mode to work, using the Magmar and Mantis as a reference. If you compare how the controls work for a one-handed creature with a two-handed creature, and in some way, import the working Mouse VSIM controls over to creatures like the Mantis, Trog, and Magmar, then, if they work well, you could "mirror" the VSIM for the right arm so that it also works for the left arm. This is just a theory, thus I have no clue how much it would take to implement this. With that in mind, I think I'll back up my folders and see if I can experiment with this a little myself and see what happens. *Puts on crash helmet*
