I've written a small utility in visual basic that will convert Arma 3 Alpha Missions to Beta. It uses a txt file using the information you have supplied here, that can be easily updated by anyone as these weapon and other name changes are discovered. It's a very easy to use - no scripting or dos, just click a couple buttons.
I wanted to make sure you would be cool with me releasing this since really it is nothing without the work you have done here! Thank you for that!
I wanted to give credit since again, the whole thing only works because of what you have done. If you'd like to take a look at it, I'd be happy to send it through email so you can test it/see how it works.
Sorry, I'd PM you but I'm too new to the board so it won't let me.
Have a great night,
