This isnt my code but I have a code for a Nature Modifier but its for the Japan version. If someone can fix it to work for the US version then you can all spam the hell out of it if you so wish. For the person who DOES convert this would you mind placing the code changes in like... blue text or something please? I have to hand type my codes...
::PKMN Nature Modifier (Hold X, Press Left then Press Y)
:::For this code, you need to go to the Summary Screen for the Pokemon's Nature you wish to change. When you are in the BLUE Screen you will hold X (don't let go of the X Button until you're done), it will take you to the RED Screen, then press Left, it will take you back to the BLUE Screen and the nature of your Pokemon should be chanhed, if it's not the desired nature press Y so it takes you back to the RED Screen then left again and repeat this process until you get the desired nature. When you are done, while still holding X, exit the Summary Page. When you are done with this process, put the Pokemon inside one of the PC boxes. It's important that you do this, because if you don't, the nature change will not take effect.
