there is another HP you can use the on labeled [pulse phaser] , READ the readme easy to overlook,
I made it for my self , cause I have a low end computer, But It seems as tho the firing of disruptors from the center maybe a-lot more common than just a low end system. I was afraid that mite be the case.
but you can rename the [pulse phaser] and it will fire a phaser that looks like a pulse\disruptor.
from the readme
there are two Hardpoints, if you have disruptor fire comeing from center, try this, rename the Hardpoint [pulsePhaser HP]SFSY_TMP_BOP.py to where it read only SFSY_TMP_BOP.py..
