weapons is somewhat complicated, you have to open DLL files with Hex Editor, you can get hex editor here:
https://mh-nexus.de/en/downloads.php?product=HxD20 "but you have to learn how to use a DLL, and if you want to put the name of the weapon on the fire control radar you have to unzip the folder Weaponcontrol.grp, it's simple, you just have to paste the decompress.exe in the interface and create a .txt
and write: "decompress WeaponsControl" or whatever the fire control radar is called in your interface and you convert it into .bat format and open it, it will automatically unzip the folder, if you already modified the panels to the name of the weapon, it does not mean that it go to shoot but it is to make it more realistic, to put the texture you have to use the CMPUTIL.EXE and
create another .txt and write to it
cmputil WeaponsControl filename.bmp
and you will have your panel, by the way the weapons are complicated, do not worry I am investigating about that, You can also modify at least the position of the guns in the database
