halo 2 on xp?

how do i do this and where do i get this stuff

 

first off that game is on vista and second off if your talking about pirating it thats illegal and you should be ashamed.

 

Actually Halo2 and Shadorun have been cracked letting XP users play the game without the need of DirectX 10.Dont know where to get the files but google Razor 1911 as they are the ones that made this possible
