"Cheater"
I don't think you clearly understand what you're asking for yourself. They are called Cheat Codes, not Help Codes, for a reason. We post what "cheats" are available, which is not always the case for every game. Some games don't have old school cheat codes, but instead you must complete or perform a specific task to unlock the rewards. If you are looking for a Help Guide then go to GameFaqs.com and find the walkthru you are looking for.
Perhaps you may find this interesting. Game developers are beginning to stray away from cheat codes because it shortens the game life. If you buy a game and play through it legitimately then you are more likely to spend a longer time with it. If you immediately start entering cheat codes to skip to the last level then you are more likely to return the game or stop playing it entirely.
