Cannon and MG's

[Steven190]

I just installed an new JS and have a question.

I have the cannon and MG assigned to two buttons. one for each. It works in most aircraft except, of course my favorite, the FW 190A-8

All the guns fire when I pull the MG button, and nothing happens when I use the canon button.
It is on the A-8 only, the A-5 works and the Me 109 work. Is there something in the Aircraft file? I looked but really could not find anything that stands out.

It happens with the 1% Av History planes, I have not tried the stock one yet, but will

IIUC you should search the gun folder to find the specific <gun>.xdp used by the <aircraft>.xdp, then search the weapons folder to find the specific <weapon>/<weapon>.xdp used as DefaultWeapon in the <gun>.xdp. This weapon should have a WeaponType, either shell or bullet. AFAIK this governs the way the gun is shot.
