It is intended to replace Core for assembly only. It's not yet ready for a formal release; there are a few bugfixes and features I need to add. I just needed a DL link serachable and up as it's used as part of the VBA2 build process. (In a way, I'm using that as a trial run for ColorzCore).
It uses about 20-30x less ram than Core (that's a lot) and runs about 20-50% faster (that's a decent amount).
Also for some reason trying to build VBA2 with NL's Core errors without telling me the error; I was going to provide some benchmarks but shrug
