I'm working on it.

I just managed to get a few of my scripts working, and now have my in-game Options Menu working in FO:NV. I still need FOSE (or rather NVSE) before I can get all my scripts running. So none of my weapon effects will be enabled, but you can change the timescale and you can select which Reduced XPR multiplier you want to use (and change these at any time).
I'm going to try (note the word "TRY") to release something late tomorrow, even if it is just a beta version of my NV Realism Core module.
