Baseline (Widescreen) Solution & Issues
Just open videosettings.src with notepad in \Techland\Xpand Rally\Data, and change standard resolution with your favourite one. This leaves you with a Vert- result, however. Refer to Additional Images.
The FOV settings are in a file called model.scr. Each car has a model.scr so any changes would have to be repeated on each car model.scr. In total there are 10 cars, so ten files would have to be editted. The location of these model.scr files is:
..\techland\Xpand\data\cars\"car directory"\model.scr
If you look within the model.scr file you will see the 5 different views possible for each car. Each view has its own FOV setting. I have not played with these settings yet so I cannot comment on what a good setting for each one might be.
This will give you a Hor+ result. Refer to the In Game Screenshots.
