Lighting Effect in PC....

Hi can someone help me how to fix my problem on turning on the lighting effect on my pc. my pc did not match some of the requirements recommend by ea so i want some answers to all of you on how to turn it on. i dont need to buy a video card coz no money you know !
thank you!

The game will not allow you to enable lighting if your video card doesn't support it. However, I believe you might be able to enable lighting if you replace your settings.dat file with a file that has lighting enabled.

well u can always google up sumtin called 3D analyze it makes ur game think u have a video card that can support lighting. it doenst work with all game tho

How do you replace the setting.dat file with a file that has lighting enabled????

Won't do anything.
Guys, you have to understand that if your video card doesn't or barely meets requirements, you're probably not gonna be able to turn on a lot of settings, particularly lighting effects.
There's just no way around it...
