I looked at the VSDI and VDSII files and after comparing them theres a bit where this comes up:
On the VSD-I it looks like this:
firingAlignmentType "Default"
TargetCountPerBank:FRONT 1
TargetCountPerBank:BACK 0
TargetCountPerBank:LEFT 1
TargetCountPerBank:RIGHT 1
On the VSD-II it looks like this:
firingAlignmentType "Default"
TargetCountPerBank:FRONT 0
TargetCountPerBank:BACK 0
TargetCountPerBank:LEFT 1
TargetCountPerBank:RIGHT 1
I don't know if this would actually work but you can try setting the 0 to 1 in the FRONT section in the VSDII. I'll try it out myself and see if my game explodes.
