This looks great! I've been looking for more mods to add a bit more complexity (without hitting Pyanodon's levels). Is this compatible with K2 and SE, similar to the BZ (Brevven's) mods?

Edit: I tested them and can confirm this is compatible

Hi.
Sorry to have been somewhat less responsive to requests, I had just about finished an update that would add some experimental extra intermediates when the first thread about K2/SE came in.

It'll run with some manual tweaking to the dependencies, but recipes will be strange, you won't be able to make molten or enriched zinc, etc. Give me a few days and I should be able to make them compatible. Since my computer is not the greatest and I have the patience of something too impatient to come up with a clever metaphor, I've never played through either mod and have been sort of taking a crash course in how their progression works.

Oh ok, good to know.
So far I'm having a lot of fun with your Brass and Nickel mods, great work :)

Thank you! The latest version has K2/SE support, give it a whirl.
