Well, I tried a 2008.1 map, and it worked fine. Haven't used it enough to know if it's much different from the 2007 ones or not.
It's interesting that I have another "2008.1" map, but it's a different size, and I haven't installed it to see if it's a different version.
Still trying to sort out all the different versions, etc. Still undecided whether it's worth much effort...
All the visual mods everyones doing to the user interface are really cool though and I thank everyone who's been contributing and working on those!
