Okay - I'm down to this one config issue. I'm trying to get Galacticraft to recognize another item as equivalent to Raw Silicon. There's a handy setting for it in the config file. The item in question is the Silicon Ingot from Inductive Automation, but at this point, I'll settle for Nether Quartz (as you 'cook' Nether Quartz in the Advanced Furnace to get the silicon ingot, so it's essentially 'raw' silicon.)
Using shift, control, alt, or any combination of those in NEI does not provide me with the item names. I suspect this may be a feature of some 'developers' tools'.
I'm not even certain if I'm entering the item name into the config correctly, since 'itemquartz' and even just 'quartz' (taken from the vanilla Minecraft wiki) show no change in the recipe image for the basic wafer. I could be wrong, but I would have thought that I'd see a flip-flop between the Raw Silicon and the 'alternate silicon' images.
