Making any weapon fire-able from a vehicle.

[Davemcrlol]

Now i know that changing the class of a weapon within the weapons.xtbl to pistol or smg makes it fire-able from a vehicle, BUT doing this to a launcher or special weapon screws up the projectiles, making rocket launchers shoot a single bullet instead of a rocket and so on. Well i was wondering if there was a file somewhere in the saints row 3's cache that defines the weapon classes and states which ones can be fired from a vehicle, something along those lines. I believe that changing the class restrictions on the launcher classes and whatnot could allow you to fire these weapons from a vehicle with their original projectile. I just need a little help finding something that could possibly lead to this.
