or more precisely.. fallout 2 was made with the same engine as fallout 1.. ( albeit a somewhat updated and modified one.. )
you can extract the maps from fallout 1's dat and load them into the editor..
and the scripts should work..
however, the fallout 2 scripts are in a different order to the fallout 1 scripts, and some have been superceeded..
so you would have to add the old scripts to the end of the fallout 2 scripts in the scripts.lst, and then edit all of the maps to point to the right scripts again.. ( since for example, the script for a door in fallout 1, is now the script for a raider.. )
Alright, thanks guys, and I checkout out Ian-Out, it's looking good!
And ColJack - Yeah, I understand what you mean, seems a little difficult just for some minor changes.. I just wanted the interface and such, but yeah thanks for the help
