Hey guys. I found widescreen fix to Freedom Fighters from site bellow. There are three files d3d8.dll, ff.ini and ffw.dll. I copied these three files to game directory and changed resolution in ini file to 1920x1080.
When I run the game I have information that freedom exe stop working. When I delete d3d8.dll from the game directory, the game run but it's stretch.
I installed directx 8.1 from CD and I also installed DirectX 9.29.1974 Redistributable, but the game still not working with d3d8.dll in game directory.
For now I have Windows Vista 32 Bit and I don't know if this fix works on different operating systems.
