d3m0n1q_733rz, why wouldn't you create a fork on github? would be easier then copy-pasting and less error-prone.

A) I can't actually program from scratch and most of my changes or just logic based.

B) Almost nobody gives me input on how my changes affect their hashing anyway.

C) People might end up sending me incessant requests for changes that I couldn't keep up with.

Besides, this is more of a hobby for me than an outright project and I want to be able to drop it like one without people getting caught in the wake.

I've commented out some of the optimizations I've been playing around with so you can see what I've been trying. It seemed like the prefetches actually slowed the code down for me. AMD users might have different results. Here, I've taken the liberty of even supplying the AMD users with the SSE2 code for ease of use. I ended up leaving in the loop modifications I made just because I couldn't tell much difference honestly. But I'm going to bed.
