Usually, a Poke`Mart. But it depends on the code.
there probably is no code- the effect is probably permanent untuill you use a code to revert your Pokemon back to normal.
You have to use cheat code.
No. But just use the Pokemon modifier code.
you use it to use other codes ex. the code you use disapears use a mater code it will work
use a code
you get a Pokemon that knows sweet scent and use it in a grassy patch
use a master code
if you are using an AR code to modify the Pokemon you catch just go to the safari zone and use the code. if not just use a Pokemon that puts it to sleep. HOPE THIS HELPS :-D
You can not use a cheat code you have to do it by work
Use the code on an action replay
you could trade from the other Pokemon games or you could use a cheat code or you could use an action replay code.
