Have you started the porting yet? I ask because I'm tired of waiting for Port Authority and a port of EV, so I've been using ConText and ResStore to pull a port of EV to EVO into a spread sheet, and have it automagically move the data around to where its supposed to be for Nova (and fill in the blank data with 0s or -1s as appropriate).
I've only made spreadsheet converters for systs, spobs, dudes and govts thus far, but you are welcome to use them if it will expedite your porting project.
If you're interested, I'll post them along with instructions. As I said, it's only four resources, but I plan on making conversion sheets for all of the resources in time.
