I'll upload what I've done thus far, the Gameplay.constants file has been entirely fixed (still with your market, tax, and trade rates, plus other changes), so you do not have to worry about that. GalaxyScenarioDef has been fixed as well, as I said, the only things "missing" are things that were put in for some my maps, and are thus negligible, or my personal responsibility. Edit: Here's entity.manifest, Gameplay, and GalaxyScenDef, all three work for 1.2. Here's the strings file that I forgot to include with those.
