Tried searching forums for this without luck. Want to get Mapper going for FO2 GOG. When installing mapper it says fallout 2 isnt installed, which I accept might be a result of it not being a vanilla original version. But after getting mapper installed it wont run. After several screen flashes and a brief frame of the mapper screen appearing, it pops up with some kind of crash error. I already changed the mapper2.cfg to direct it to where the master.dat is and the master patches, and turned librarian=1. That allowed the program to run. But then it still crashed. Also, I upgraded the SFall mod to 3.3 using the installer (GOG version comes with 3.1 or 3.2, not sure which).
