No there is not, maybe what you have heard/seen is modded.
That is not something that can be done in any Nintendo game.
You hack it
No, you cannot do this.
There is NO such thing as action replay for nude only mods can be used to nude characters
hack it online
sorry but you can't or i can't it's up to the "MAKER'S" choice to make a new Pokemon game with a nude code.
there is no code you will have to buy it silly if we give out codes to be nude dont you think the little 14yrs old kid would be naked all the time
Dude there is no nude code for any tomb raider, Because they would have alot of legal issues atleast the minimal age would be greatly increased and because of that it wouldn't be legal in some countries.However if you have a computer with tomb raider you can find a nude patch wich will make her nude, Try using a search engine and type "nude raider".In most search engines it wil be the first link
you must do a certain code
there is no nude cheat
I don't think there is one.
Yes you can be nude for a massage.
