Looking at the xml I see all the types of guns and missiles listed but in the program have like only three types of guns, two types of rockets and two types of missiles. Can  and how do I add the others?

Yes, I saw that and downloaded several. Trying to figure out though in the xml how does it select which weapons it will use from the ones listed? I noticed in the program you have the choice of three guns, two rockets and two missiles? Where can I get a more comprehensive explanation of the csweapons.xml entries and how to use them?

Yes, I read all of that but still am confused as to the weapons selection that shows up within the program. There are over twelve listed in the default xml and only what, seven show up on the hud and it doesn't appear the are taken in order. Maybe someone could show me another example of the xml? I have been comparing the ones I downloaded still can't see the pattern. Sorry. What everyone has already done works great I just want to figure out how it reads the weapons it uses.

You should be able to access all the weapons in the CSWeapon.xml on the F/A-18 Armed (if you have Acceleration), and any aircraft/rotorcraft that you add the Weapon for FSX to using the Loader.
