I'd like to argue about Gold Age being Lighthalzen episode heh. Just kidding, Here's my take :
-First, you should use pre-renewal conf so that you get old-style damage formulae. If you want to go from latest and downgrade, refer to points below.
-You'll have a lot of "official" informations of good ol' times on iRO Wiki classic (including formulae on nearly everything) : http://irowiki.org/classic/Main_Page
-Then about the maps, you can just use the map database on ratemyserver, Obviously, be careful on picking "pre renewal" : http://ratemyserver.net/index.php?page=map_db /
