Civ 2.78

So I installed Civ 2.78. After solving a few self-inflicted problems, I'm left with one I can't solve: All the colors are mixed up. My green tribe is now orange (unit shields, city size numbers and the city names) and green (city flag). And, I now have two purple tribes, though one shows up as teal in the mini-map. (see picture below). Nothing else is messed up. I've attached the cities file, in case someone wants to get a look.

I'm guessing there's something wrong with your units.gif.
All Civ2 graphics use the color palette of the units.gif. It looks like that palette has a few colors mixed up, affecting the tribe colors.
