Yes you need everything listed in the ItemsConfig and BlocksConfig as it are the original files where the game is build on. For the Config.ecf its the Items Part thats broken due to the increase of the Id Numbers. The IdNumbers shifted for this. Since API Modders (cShar Mods) read this file for there mods to make a call to the ItemsExchange they got errors as they need the original IdNumber. We fixed the file for them. Result it wont work for modders anymore who want to make changes in this file. As i said its ONLY the Items part that doesnt work. The Blocks Part, Entity Part, Loot Part still works. But as it will NOT be fixed anymore, better get used to the Original Files now as the Config.ecf might break in the future compleet
