Yeah, I know. We got that topic already often here and there... Still. I played around a little bit right now and figured out a very easy way for setting up a Fallout 2 mod without overwriting original game data. So I thought I might share this with you guys... It's pretty easy, just follow these steps: 1. Install Fallout 2 into a folder of your choice. 2. Now create the mod folder in your Fallout 2 folder. 3. Put all mod files into this folder as if you would overwrite Fallout 2. 4. You need to have the Fallout2.exe AND fallout2.cfg file in the mod folder. 5. Now change the entries for critter.dat, master.dat, patches, music, etc. in the fallout2.cfg of the mod folder like in the following example: Code: music_path1=data\sound\music\ music_path2=..\data\sound\music\ critter_dat=..\critter.dat critter_patches=data master_dat=..\master.dat master_patches=data 6. That's it. If you now use the Fallout2.exe in the mod folder, it takes the critter.dat and master.dat from the previous folder (Fallout 2 installation) and uses all new files from the mod folder. In combination with Sfall you (the mod creator) can also set your own *.dat file and place it in the mod folder and the original Fallout 2 folder stays nice and clean. If you still need an example on how this works, you can download the german or english version of my Shattered Destiny 1 mod. I made new setup files for it with the same method. You just need to extract the mod folder into your Fallout 2 folder, then use the new created desktop icon or go into .."\Fallout2\ShatteredDestiny\" and start the game with the Fallout2.exe from the mod.
