let's get one thing straight: there are no cheats written into the code of halo. the method you described only works for halo CE (custom edition), which, by the way, has no campain and will not allow you to play games on the internet with devemode enabled.
however, there is a way for you to get cheats on halo PC: download a trainer.
i'll try to find you one
