Ok, I've uploaded a rather hackish version that runs. I already know the icons are broken.
The good news is, it didn't crash immediately when I tried it out on some items (well, about 70 restarts and fixed later), the bad news is that calculations in the game have changed dramatically, so the results might or might not be wrong, especially when space age features are in use.
If you have a crash, please paste the calltrace, and tell me which entity caused it, if possible.
Likewise, if calculations are wrong, drop me a note as well.
I have only tried this with an old game from a year ago, I haven't even started anew space age game yet, so bear with me.
