Battle Realms

Hor+ solution:
Replace Battle_Realms_F.exe and D3DIM700.DLL in the game folder from these archives, files available from the PC Gaming Wiki Community Files (search there).
Battle_Realms_widescreen.7z - default FOV
Battle_Realms_FOV_v1.7z - increased FOV +33%
Battle_Realms_FOV_v2.7z - increased FOV +66%
(Don't copy D3DIM700.DLL file, if you don't uses resolution higher than 2048 pixels, also don't copy it on Windows XP and Windows Vista)

To set up resolution, edit Battle_Realms.ini file in the game folder, change following strings:

[VideoState]

Width                   =1024

Height                  =768

to the desired resolution, for example, for 1920x1080:

[VideoState]

Width                   =1920

Height                  =1080

Vert- solution:
Use Battle Realms Custom Resolution Patch (current version only works with the GOG.com release). Follow the steps in the readme.

All 2D elements are stretched from 4:3. All 3D elements are Vert-.
