The Simpsons - Hit and Run
This game is a classic. One of the few Simpsons games to be any good. It's basically a GTA clone with no guns and everyone is yellow.
Anyway, the hack is easy this time. Just download the widescreen exe and put it in with the other game files, where the original exe is. The readme file will tell you what resolution is what.
The only issue is that instead of extending the FOV, it crops the FOV, which means you're actually seeing less than if you played it normally. For the most part, the camera is pretty far out anyway, so if you're used to the more recent sandbox games out there you'll have no issues. Don't be alarmed that the main menu is still stretched, as well as the HUD, this was probably done so no important details are missed.
