Changing nicknames/trainer ID?

[Rekkuza]

Is there a gameshark code to make it possible to change a traded Pokemon's nickname? Or a code to change your trainer ID (and make it possible)? I know you could do this in RBY..

I don't think so.

If you use xyzman's Pokemon Cheat Calculator (I don't have the link, but just search for it on Google or something), you can change your Trainer ID, so maybe that could work.
