if any/all of those have something like an in-game zoom of some type, sniper rifle or other wise.
You can probably use that with a generic memory tool like cheat engine,
example, fov is 90 regular and put to 40 for 'zoom effect', once you isolate where that value is, you can set whatever you want.
I wish I knew doing all that stuff but that's not the case. Thanks tho.
I think there must be an easy way of gaining just horizontal FOV because many games support the aspect ratio fix for rectangular pixels natively (disabled you get an stretched picture; enabled you get a proper picture).
Racer_S' Far Cry 2 hack does just that for me; I select 1024x768 resolution and then I configure the hack as follows and it fixes the stretched picture:
1024x768 / No AR correction
1024x768 / AR Fixed
I wish the games I posted supported this fix too...
