Reverse your question and we will be more than happy to give you a clear answer. It seems vague
you can reverse cheats by simply typing them once more in gta games but some like GUSNHDE cant be reversed.About other games I dont know.
typing the cheat code a second time usually removes it
You can't reverse ageing, even with cheats, but you can turn aging off in the options screen, sorry man :(
If you used any cheat with "true" in the end, just re-type the cheat with false. for example if you used "boolprop testingcheatsenabled true" then you just type "boolprop testingcheatsenabled false". Same thing with cheats that end with on, you just re-type the cheat with off. for example "moveobjects on" would be unactivated with "moveobjects off". there are some cheats that you cant reverse though, like kaching or motherlode (money cheats) Hope that helped :)
