tdy99: Are you sure it is freezing up? It takes over 6 minutes to load a game save file from scratch. The first two times I tried starting ROM-AND I thought it had frozen, as I didn't get anything on the screen for 4-5 minutes. Then I happened to start it and went off to do something else and forgot about it. When I came back it was loaded up. Whoowhoo!
Now, it is surprising I can get it to run at all. You see, I am running it in a WinXP guest on a linux host (OpenSuSE 13.0) with an athlon 64 (754) @ 2.2 Ghz and GTS7950gt, 512 M graphics memory, 2G of system memory of which my guest has only 768M available. Yet, it does run well enough to play the game. Yes, it is slow but it was about the same when I ran it in native XP. Once you get loaded reloading a saved game file takes about as much time as it did before, still maybe a couple of minutes. I have it set for low graphics, which are still pretty good, but I don't pay that much attention to graphics, anyway. And I rather doubt I could without Aforess' mods to the game engine.
I did install it as a fresh install of Civ4 in my guest install Civ4 vanilla, patch to latest patch, install BTS, patch to 3.19, installed ROM-AND 175 & 1.75b from .exe installer. Have had no problems.
For those of you having problems: on the Civ4 load screen (the small one) and on the ROM load game screen there are messages above the progress bar telling you what it is doing: Loading Python, loading xml (first screen), init, init graphics, setting up map. Write down the last thing you see and include it in your post, along with any error messages that may come up.
I understand that many people have had trouble getting this to work, but believe me it is worth it. This game really rocks. I think most of the time the problems come from a bad install, files in the wrong path, etc. and are usually easy to fix.
