1. Run the Game once to create the necessary config file.
2. Go to C:\Users\...\Documents\Cold War and copy Config.txt to ...\Steam\steamapps\common\Cold War (your Game root folder)
3. Edit your des. resolution in Config.txt
4. Rename coldwar.exe --> coldwar_setup.exe and coldwar.ex --> coldwar.exe
5. Now comes the hexedit part. Open coldwar.exe in a hexeditor and change the following Offsets:
Aspect Ratio: Go to Offset 1EF90 look for 00 00 80 3F and change it to 00 00 58 3F (16:10) or to 00 00 40 3F (16:9)
