When I say 'cheat codes', I mean codes that are part of the game itself, not codes generated by software such as Codebreaker et al. Like God Mode codes, infinite health, ammo...I find it hard to imagine that cheats are discovered by playing around with the buttons, or going through the game code, or by any means other than the game manufacturer 'leaking' what the codes are. Or do people actually set out to and succeed in finding secret cheats for games?
Actually what happens is that the game producer/developer, supposedly leaks the cheat codes out some how to the websites, or some people actually mess with buttons until something happens, most of the time those peolpe hack through the game, have no life and do it for a living or they sign on a random screen name and give it to the site and which they work for the game makers. But thats what i think.
That's something that I always wondered. I thought that codes were originally released to reviewers so that they could access all parts of the game and get out a quick review (especially back in the days where you couldn't save). Now I think that developers just release them as a matter of course as they make the game more fun for a lot of people.
