Im trying to follow the instructions here : https://www.nma-fallout.com/resources/bis-mapper.55/ But its not very clear. First, i extracted the entire download into a folder. Am i supposed to run the installer inside the download? Or has it already been run, because I can see a BIS Mapper sub folder in the download complete with the high res patch applied? It has m2_res.ini at least. I setup the data paths and the m2_res.ini as described. OK. I then copied the killap patch folder into the mapper script folder and overwrote everything. Then i tried running mapper2.exe, at which point it kept complaining that it could not initialize the video. I found an old thread by someone saying that they managed to get it to work by setting compatability settings to use 640x480. I tried this and the program launched, but I just got a black map screen afterwards. Is this normal?
