Playing Guilty Gear in VS Cabs


Camel Slug
I've got a dual cyber lead setup with a naomi system in it. I have no problems playing marvel vs cap 2, cap vs snk 2 or melty blood on the setup. However, when I put in either guilty gear x or guilty gear xx accent core in the dual cab setup, I am unable to use the controls on the slave cab.

I was wondering, if I need any additional equipment to set this up or if there is a setting that needs to be changed.
