i have beat the game on normal and now doing it on hard with cheat activated (of course with said given instructions) and they work great and still got cheevos. make sure you enter them and quit out, dont worry about saving just quit and continue or replay. be careful if you enter cheats then save. i had an issue where all my stats stopped once cheats were entered and got to a save point. othere then that game is pretty decent and fairly easy anyways. but a quick 1000G.
