FYI..I/we did the same thing for our server with the 4.83 mod.We made an Add-on mod that is loaded up in the flmm after loading the 4.83.So,technically,we didnt modify any part of the 4.83.All the files are exactly the same as the original 4.83....the add-on just adds new stuff to the game(1 system,new weaps and items,couple new comodities,some tweeking of existing ships so that there is a mk2 and mk3 version of the original,which is still there).And we added the thanks and kudos to everybody in the read-me in our add-on also,lest we forget who gave us the awsome basis to work from.
p.s. I love the 5.5k range for the mk2 Liberty BS turrets.Now THATS space combat:cool:
