On the other Hand, UE has begun to work together with IC2 and Buildcraft compatible mods. Nothing agains Marketism but the IC2 mashines are simply the true basics when it comes to ore refining.
In some way, with the ores he allready uses they are compatible to IC2 if you use GregTech too, if Titanium, Copper and Aluminium are part of the Oredictinary, they are allready compatible with advanced GregTech Systems and Ores, and you find Copper in Forestry too. At least when i tested IC2 with GregTech + the Galacticraft build from last week, i could use GregTech Titanium and Aluminium, and i could use Forestry and IC2 Copper for Galacticraft parts.
To make the Ores from this mod working with the macerator would make sense, dont know what you have to do in that case (truely i didnt test it to macorate Galacticraft Ores yet), but at the moment the mods IC2, BC and UE are a interlinked package.
Each mod should be able to play on it´s own. But it´s more fun in my opinion if you can play them together and get more out of it.
And to make it UE compatible is a good start.
